Wanted to give a huge shoutout to Lupe at the dental office. She went above and beyond helping me understand my insurance coverage and what costs to expect, and explained everything in really simple, easy-to-understand terms. She was attentive, followed up with me, and genuinely made the whole process feel a lot less stressful. I have a future consult scheduled and am honestly excited to continue working with this office if everyone is as caring as she is. Lupe deserves 5 stars, recognition, and a raise for the amazing job she does! read more

I meant to do this review a while ago. I was referred here by Dr. Leung in Hayward. My initial visit with Dr. Oka was pleasant. He was very informative, and you can tell he truly cares about his patients. I really appreciate his ability to explain procedures in a way that's easy to understand, almost like explaining it to a 5-year-old, so you feel clear and comfortable about what you're about to undergo. I also appreciated his suggestions and recommendations. read more

Dr. Oka is truly one of a kind. I would absolutely return to him and recommend him to all of my friends and family--and honestly, I would even bring my future kids here if he were still practicing when they needed care. I first saw Dr. Oka about a year ago for a consultation regarding my wisdom teeth. From the very beginning, he was incredibly thorough and took the time to explain everything in detail. He made me feel safe, reassured, and well-informed about my options. What really stood out to me was his honesty. While many offices might push for procedures, Dr. Oka calmly explained that I didn't necessarily need to remove my wisdom teeth unless they started bothering me. Because of that transparency, I decided to wait. About a year later, my wisdom teeth started causing significant discomfort, so I returned to have them removed. Long story short--Dr. Oka did a fantastic job. He is extremely skilled and truly goes above and beyond to ensure the safety and comfort of his patients. The entire office staff is also wonderful. Everyone is incredibly helpful, kind, and professional, which made the entire process smooth and reassuring. A special shoutout to Lupe and the rest of the team for taking such great care of me. After the surgery, Dr. Oka even personally called to check in and provided detailed care instructions since some discomfort was expected. As someone who tends to overthink (and as an RN myself!), that extra level of care meant a lot. He even kindly offered to see me sooner than my scheduled follow-up if I had any concerns. Knowing that the office also has a 24/7 emergency service line gave me even more peace of mind. Overall, I cannot recommend Dr. Oka and his team enough. They provide exceptional care, and you can truly tell that they prioritize their patients' wellbeing. read more

I had my wisdom tooth extracted by Dr. Oka a couple of days ago, and I can confidently say he's an incredibly patient and caring oral surgeon. I had all four wisdom teeth, but only one was causing issues. Dr. Oka took the time to explain everything clearly -- why removing the problematic tooth was necessary and why taking out the others right now could do more harm than good. His calm, honest approach really put me at ease. Everyone's healing experience is different, but I personally had no pain or swelling after my surgical extraction. If you're looking for a skilled and trustworthy oral surgeon, I highly recommend Dr. Oka. read more

1. Overcharging with wrong calculation on patient's responsibility. 2. They don't remind you of your appointment in advance. They called me the day before my surgery when the office is closed, around 8 pm, and my appointment is no where to be changed. 3. And they don't tell you that if you need to call 2 days in advance for rescheduling, and also, the Canceling fees is 300 dollars. Even if you are sick and cannot go for a surgery. 4. The front desk lady is not professional enough to blame me that I have not called them in advance. I am very angry about this place. Don't recommend. read more

Very well run and efficient office. Everyone is helpful and explains the procedures very well. Dr Oka is very personable and calmly explains all he is doing. I can recommend him heartily read more

We took our 8 year old son to Dr. Oka to remove an extra tooth sitting above his two front teeth. We first had a consultation to go over the procedure and any concerns. Then we scheduled another appointment for the actual procedure. Dr. Oka is calm and very good at making parents and kids feel comfortable with him and the procedure. My son isn't the best with needles and Dr. Oka pulled out all techniques to ease anxiety and pain. Our son woke up and was able to walk to the car on his own. I subtracted one star because there was a miscommunication in appointment time but they were able to accommodate us when we got there. Super appreciated because our son had to fast with no water and skipped school. read more

Our teenager woke up with a severe tooth ache. Dr. Oka took us as a brand new patient and treated our son like he was a long time customer. He helped reduce the pain immediately and quickly schedule a surgery. Dr. Oka removed four wisdom teeth from our 17 year old. He met did a consult with the parents and patient first; he clearly communicated what to expect and how to prepare. He answered all our questions. The procedure went well and weeks later, our boy is doing fine. I would use Dr. Oka myself for any oral surgery when needed. He was professional, courteous and a great communicator. Does his office staff need some training? Yes. Did it affect the service he provided. Not at all. I would recommend him to my family and friends, without hesitation. read more

Had teeth removal. Dr Oka is great! 5 star for thoroughly explaining everything, professionalism and talent! Front desk are nice and professional...but being able to reach them is difficult. Have to keep trying! Office space is nice...but the chair to lay on during the procedure looks old and ripped! No plastic covering it.. read more

**Experience during COVID19 Pandemic** For some background, I put off having my wisdom teeth removed for 4 years. Despite having the pain of an impacted wisdom tooth grown in, I told myself that it wasn't worth the hassle and the recovery required a lot of time off from work that I didn't quite have prior to COVID19. I wrote in via email to Dr. Oka on a whim, to make an appointment in the distant future. To my surprise, I was called back by the kindest receptionist (I believe her name was Lupe) who walked me through the process extensively and got me scheduled only 2 weeks out! I was terrified and in pain from my wisdom teeth as well but she reassured me that I would be okay and that they would call me if they had an opening sooner. She is truly a gem! I came in for my surgery early on a Monday morning. An assistant took my x-ray before Dr. Oka came in and told me that they would be putting me under due to my impacted wisdom teeth for the procedure. I then was able to walk through my insurance and payment plan information with an assistant named Crystal, who made it very easy and explained everything very well! I then had my surgery which felt like literally 10 minutes due to the anesthesia. After the surgery, I did have to call in to make sure my symptoms were nothing that I had to come back for. I was reassured by Lupe that my symptoms were normal and given tips on how to take care of this. My follow up appointment was very quick! 5-10 minutes to check in, no abnormalities! I got a doctor's note from Dr. Oka for work and was on my way! Overall, I had a very seamless and positive experience! Thank you, Dr.Oka and team, for making this experience (that I was dreading) much easier than I anticipated! read more

I took my very high risk for covid, immunocompromised, elderly mother here for a tooth extraction. The receptionists staff were NOT MASKED (currently covid is high red transmission and in California medical services they are suppose to be masking), they were very rude when making the appointment (it took a month and a half to get a consult appt. and me talking to an outside answering service despite calling right after the missed calls). I should have picked someone else after this red flag but our regular dentist is so great and I trusted their referral. I was shocked and in disbelief to see the staff unmasked that I just let my mom go to the consultation without thinking. She said the doc and his assistants were masked but I called her to leave after the estimation. Dr. Oka said he would do the extraction then and there and my mom did it! She argued that she really needed it done and will not come back after. THEN they insisted to have her come back for a follow up due to her health! Wow, to ask her to come back and risk being infected by your unmasked staff? Do they even test staff for covid? Wow I refused to let her go back there. If you are high risk, I recommend you call medical providers before to see if they are still considering covid precautions like masks, not to mention monkeypox is out circulating now. This ableist culture needs to stop and I can't believe medical providers like this aren't protecting themselves or their patients. read more

The WORST staff I have ever encountered. Too bad because the dentist was highly recommended by my family. The person who handled my appointment was RUDE and OBNOXIOUS. I plan to cancel my appointment after writing this and will go somewhere else. If the office staff is this bad, I wonder how this will reflect on the dentist. The staff needs retraining or let go all together. You may lose business because of this. Think about it. read more

I has recently surgery to remove an infected tooth. He was very knowledgeable comforting, great demeanor man. I'm definitely recommending Dr Oka to all I know!! Great staff, kind and knowledgeable. read more

Amazing doctor. Spends a lot of time explaining the procedure in detail and in simple terms. Very courteous and caring doctor. Front office is efficient and explains the cost of procedure in advance. read more

I do not recommend. Overbilling. It is a trap. stay away. my honest opinion.I called and they claimed yes we accept Aetna Then they changed their mind and wanted to get paid cash.I walked away and reported to my Insurance read more

I had a great surgery. Dr.Oka was fantastic and explained the whole surgery and outcomes with me during a long consultation-worth it! The day of the surgery he also made sure I understood what he was doing step by step. The last thing I remember before going under anesthesia was having a numbing spray on my arm and then I woke up with mild pain. The pain obviously got worse after the anesthesia wore off but that's it. My surgery included a extracted baby tooth with an expose and bond for my impacted canine. The surgery price was within my means so no complaint there! The front desk really helped me out with understanding how my 2 insurances fit in so no surprises and I will know what my out of pocket expenses will be if I got more help then expected or less. Thank you so much! read more

Dr. Oka is no doubt very professional. I had a smooth recovery after removing 2 impact tooth. 5 stars for the surgery quality. Totally understand why other people would be pissed, though. Their phone system is a mess and it's hard to reach their actual office staff because the office does not open often and they rely on an answering service that would bring the words to the office the next day or two. Hard to schedule time, change plans, and deal with insurance problems when you can't discuss over the phone most of the time. read more

Dr. Oka is without a doubt one of the best oral surgeons in the Bay Area. He removed all 4 wisdom teeth from my twin daughters. I took one of them first because she was complaining of pain. It was getting impacted and we moved forward with the removal of all. It was a smooth process from begining to end and she experienced just some minimal pain and discomfort afterwards. She was well within a few days. No infections, no pain, nothing. I took my other twin just recently for the same situation as I fully trusted Dr. Oka and the process. Also his staff is very friendly and helpful. They followed up with phone calls and are very professional. If I have a need for these type of services again, I will be returning to Dr. Oka. read more

Dr. Oka is kind, patient, friendly and most importantly a fantastic oral surgeon. He explained everything in detail and gave me all the pros and cons before he did the surgery. He is highly knowledgeable and I trust him 100 percent. I'm only sorry I have to see him again because it means I have to have another tooth pulled. He puts me to "sleep" so I don't feel a thing. And he doesn't rush you out the door when you're still half out of it like a periodontist in Hayward did. There's a little area to lie down until you are able to walk on your own. Of course you still have to have someone drive you home but at least this way you can get in and out of the car by yourself. I did pay extra to be sedated of course. But for me it's worth it because I have fibromyalgia. read more

In need of an oral surgeon for wisdom teeth removal? A physician who is skilled/experienced, professional and with a calm bedside manner? Then go to Dr.Oka! He is amazing! He explains in a matter that is understandable, he is kind and his experience is visible in his great quality outcomes. His staff is friendly, they are responsive to calls and questions and even the answering service is polite and professional! read more

Dr. Oka is a great oral surgeon. He treated my 10 year old daughter recently. He very patiently explained the procedure to my daughter in a way a 10 year old would understand but not feel afraided. My daughter was apprehensive about the procedure being seen by Dr. Oka, but Dr. Oka calmed her down. The procedure went smoothly and she was done within an hour. I trust Dr. Oka and highly recommend him. read more

Dr. Oka is simply amazing! I need to have my three wisdom teeth removed. He walked me through why it's necessary and potential risks after reviewing x-rays. He helps me visualizing what to expect during the operation. I was instructed to take the anti-biotics and pain-killers before I can feel anything. It turns out to be the best decision since first six hours is very challenging. But I am so blessed that I barely feel the swelling on my jaw areas and I have been recovering fairly fast for my first week. I would highly recommend this place and it was a very positive experience for me given the professional service I have received from this place! read more

I had 2 weeks until I flew back to NYC and needed my wisdom teeth extracted. I called Dr. Oka's office and they were able to find a same-day consultation + surgery appointment that same week. This was the easiest and smoothest wisdom teeth extraction I've ever had, but also the only one I've ever had. The staff will go out of their way to make things happen. They were nothing but friendly and helpful. read more

Excellent experience! If I had to get my wisdom teeth pulled again (I pray I don't) I would go directly back to this office. The entire staff is not only very kind and welcoming, but they also go out of their way to make sure you understand what is happening from the procedure to the follow up care to the billing. The doctor even called me the evening of my procedure to check and see how I was doing. A-1 patient care. read more

My dentist (Dr. Barr, Chang & Poindexter ) said that I needed my wisdom teeth removed and they recommended us here to Dr. Oka which is conveniently located in the same plaza as they are. Now let me tell you, this review is basically wayy long overdue. I got my wisdom tooth pulled and removed wayy before I even began Yelping. We scheduled an appointment and the assistant at the front desk was friendly. I believe I meet Dr. Orka that they as well to get ourselves familiarized with who would be pulling out my teeth. On the day of my appointment, I followed Dr. Orka's instructions and had not drank any fluids or eaten anything because I would be sitting and passed out for quite a while, as he would be working on me. Dr. Orka's a pretty friendly guy, he's Japanese I believe. He's friendly and explained things very thoroughly to make sure I understood everything. The treatment went okay, although my parents were a bit worried because it took a while for me to wake up from the sleep medication. I woke up eventually though... There weren't really any problems other than me returning for a few check ups to make sure everything was okay. So, why the 4 and not the 5 like most everyone else? Well, I mean, come on people, I got my teeth pulled! read more

I needed to get my wisdom teeth pulled and I was recommended by a friend to come here. BEST DECISION EVER! Dr. Oka was extremely knowledgeable, detailed and def made me feel comfortable. He explained everything very well. Working in a dental office myself I see that some people have insurance issues, but aside from that, patient care and treatment was superb. I came in for a consultation, everything went super smooth. Scheduled for my extraction including IV sedation and the whole procedure itself probably took 45 mins. Diego, Lupe, Reina and Brie were awesome. Diego was the assistant who accompanied me and he was great! Recommending dr. Oka to anyone who needs their teeth pulled. You won't be disappointed! read more

So utterly impressed by my whole experience visiting Dr. Oka and his lovely staff. Dr. Oka explained everything to me so clearly and was very through. I've never had a doctor make me feel such at ease, like I was in the BEST hands. My difficult extraction was nothing for Dr, he pulled that tooth out and I never even realized it was gone. I was out of that chair in 5 mins flat. I will be recommending everyone and anyone with pleasure. Thank you so much Dr. Oka and Staff! read more

Unreliable. 09/27/2018, I went to Dr. Hidemi Oka for wisdom tooth extraction. He's good but his team did a bad job. They told me give them CASH before surgery operation, and then Insurrance would give money back. But after 02 months... Nothing. I called them and asked checking again. they forgot and answered me that I would have money after 04 weeks. Now is nothing again. Insurrance answered me: " Please have your dental office submit the claim and the x-rays to the below address". I called dental office one more, and then they kept answering that "you must wait, we did do everything for you". I hope dental office can do clearly. thanks read more

I have to say I'm so lucky to have found a good trustful oral surgeon to do my teeth extraction (all 4 wisdom teeth). Because of the intense pain I had during quarantine I was able to get an appointment pretty quick. By the time of my consultation Dr.Oka had showed me my xrays and explained how bad I needed this surgery. Then he followed by explaining what he was going to do on the day of my surgery. Afterwards I had an estimation of how much my insurance was going to cover and what was expected by me and I was so pleased. Following up my surgery I came in with my dd who waited for an hour and half but because of how quick and easy I was put to sleep it felt like 20 mins haha. Next thing thing you know I'm already home following his orders with medications and diet. By the time I had my follow up appointment everything had gone exactly how he said it would. Btw I have to give props to Lupe as well because she was the one who helped me with my insurance, the dates, and phone call reminders. She was really friendly, helpful, and honest throughout everything. Would I recommend this place? Yes. read more

This is my worst experience and worst customer service attitude！When I came to the office I saw that the front desk staff was sleepy and talked to me.In the special period of coronavirus still without masks and gloves ！Disinfection was ignored in such an important place! When patient came to here didn't tell them how much consulting fees have to charged，After gave me a bunch of price lists, Just said that they need to charge 236 dollars for that！They didn't provide X-ray to me. Its around 15 minutes communicated with Doctor only，They didn't tell patient the price before the inspection. How they charge depends on their mood! no price list show for me.remind everyone to be careful! This is the first time I have been to such an unprofessional place! read more

Hidemi Oka, DMD MD - Oral Surgeons Near Me - Union City, California

I am a 77 years old patient with such a deep rooted fear of dentists due to trauma during childhood with experiences in dentists offices, that I preferred to treat tooth pain by whatever other means than going to see a professional. However, on 1975 I had to have root canals (or else), because of an infection and my fears and trauma were reaffirmed, so I never set foot in a dentist office not even for a cleaning again till I was forced, once more, in 2016 and that was when by mere luck I came to Dr. Oka for a consultation and extraction of wisdom tooth and bone grafting. It was a life changing experience! His demeanor, was very relaxing, the explanations extra clear and the applied knowledgeable technics help me not feel, even the sting of the needle, when injecting the anesthesia to do the surgery. I was so happy with that, that I had not noticed if his staff was polite or not. Year 2023 came and I needed to take out another wisdom tooth, and of course, in my mind Dr. Oka was my only choice. By now, he only does surgery by other dentists referrals, and as soon as I got it, I visited him and he was able to reassure me once again and I was able to visit two other regular dentist, for cleaning and fillings, with out climbing up a wall. His staff very efficiently, clear my charges with out any doubtful or confusing charges, which unfortunately, I cannot say the same for the other two dentists. That is gold. Thank you Dr. Oka and staff. read more

Extremely unprofessional I basically wasted my time coming here. Not only did they keep asking me for my insurance but they couldnt even call me before driving all the way from Hayward to let me know that their x-ray machine isnt working. Tried to compensate by sending me elsewhere which was ridiculous. read more

Reina is just rude. Talk to Crystal (sp?) But I agree with the other reviewers, they seem to only care about taking your money and not really helping you. read more

First off let me say that I detest going to the dentist. I have had awful experiences in the past which have made me stay away from any dentist for several years. Needless to say my neglecting my teeth caught up with me. I was referred to Dr. Oka to have a tooth extracted and bone grafting done in preparation for an implant. At my initial consultation appointment Dr. Oka spent about an hour with me thoroughly explaining the entire process. He knew that I was anxious and concerned regarding any possible pain that I might experience during and after the procedure. After Dr. Oka explained everything to me I felt a lot better about the pending procedure but I was still very cautious. On the day of the procedure, one minute I'm on the table laughing (from the gas) and the next minute I'm getting ready to go home. I was alert and couldn't believe that I was not in pain. Dr. Oka did an AWESOME job. Dr. Oka's warmth, professionalism and thoroughness has helped me to overcome my apprehension to dentistry. read more

My dentist referred me to Dr. Oka for an infected wisdom tooth. I had been in severe pain for about a month. I called Dr. Oka's office and stressed to his staff that its difficult to come in multiple times because I just started at my new job. They were able to get me in promptly and they scheduled me for both my consult and extraction at the same time. I came in and did my formal introduction/x-rays. Then Dr. Oka came in and thoroughly explained my situation and what's to be expected. He gave me his opinion along with other options to choose from, I went with his opinion because he's the professional and he had gained my trust. His nurse then prepped me for anesthesia and the extraction. He was very understanding and very gentle and the procedure was very fast before I knew it I was awake the tooth was gone and I was happy. Dr. Oka showed empathy and sympathy. He's confident but not cocky nor arrogant. Dr. Oka has a surgery assistant who's name I can't remember, she was nice and helpful. For billing purposes I dealt with Crystal, Crystal was knowledgeable and helpful in giving me billing options. Her caring words made me feel extra comfortable in my experience. They make a great team. Last but not least, Dr. Oka himself called me a couple of hours later to inquire how I was feeling. That was very thoughtful. If you need any oral surgery, I recommend this office. It's a wonderful experience read more

I went to Dr. Hidemi Oka for wisdom tooth extraction. He and his team did a great job. Dr. Oka explained the ailment and the procedure very clearly. He took the time to explain without rushing and made sure it is understandable to the patient. His staff Lupe and Crystal were very helpful and made the process super smooth. Highly recommend this place! read more

Dr. Oka is a pretty caring and very knowledgeable doctor. I had my consultation in February and a few weeks later I had my wisdom teeth extractions. The nurses were helpful with questions I had and helped me understand the payment plan. On the day of my surgery, I was a nervous reck! Dr. Oka and the nurse comforted me and made it easier for me. Hey, look forward to laughing gas! I was laughing and crying so much. And I totally knocked out without any idea what happened during the surgery. The doctor called me after my surgery when I was home, so that helped me out if I had questions or concerns. I did get a little sick with the anesthesia and did throw up. But luckily it was only once that happened. And I was able to eat soft foods and rest. Only one star off because I did develop some tooth sensitivity which hasn't gotten better. Been getting it checked with my regular dentist. I do recommend this location and of course do your research. :) read more

The dentist is great but the staff is Terrible. The staff is full of lies and very unprofessional and rude. They basically ignore my call for my reimbursement money and make you wait for months. read more

Dr. Oka is one of the best Oral Surgeons ever! My dentist referred me to him. I have really bad TMJ and I had to get my wisdom teeth extracted. I was very worried about TMJ aggravation after the surgery. Dr. Oka very clearly explained the procedure and in great detail, and gave me the different options I have with the surgery. The whole procedure went off without a glitch, and I had zero pain (just soreness) after, either from the extractions or from my TMJ. It's nothing short of a miracle. I strongly, strongly recommend Dr. Oka. He is everything that you expect from a great doctor. The bonus is the whole support team - reception, schedulers, nurses, every one of them are awesome. Special props to Lupe at the reception. She is extremely personable, helps with the schedule, billing etc. I honestly don't understand the bad reviews below. It seems more like an insurance/financial issue, than Dr. Oka or his office staff. I guess when patients insurance company don't pay as much for procedures, patients seem to be pissed off with Dr. Oka /his staff (who just are conveying the message from the insurance company). Anyway, my family and I have an Oral Surgeon for life, if ever we need one. Don't hesitate to ping me in case you want more info about his office. read more

Id have to admit, I was kinda nervous off the reviews here but in my opinion this place was exceptional. Not once did I feel rushed. Not once did I feel like they were only looking to take my money. Like Jay T. said, he is a good surgeon. I had my last set of wisdom teeth removed by him. The consultation was great - much better than my first go around. He explained to me what the process was going to be - it was comfortable and educational all at the same time. The ladies at the front desk were great; very polite, not rude or sneaky. They made sure I understood exactly was I was paying for before they did the extraction. If I had other teeth to be pulled, I would comeback here. I feel bad for those people that had the bad review. It was the complete opposite of what I had. read more
