I've been a patient at Diamond Creek Dental for many years, and Dr. Joseph Lee has consistently provided excellent care. I've had dental implants done here, as well as deep cleanings in the past, and every experience has been positive. Dr. Lee is extremely knowledgeable, professional, and genuinely caring. He always takes the time to explain procedures clearly and makes sure I'm comfortable, which I really appreciate--especially with more involved treatments like implants. The office staff are also wonderful--friendly, helpful, and well organized. The whole office has a calm, welcoming atmosphere that makes dental visits much less stressful. Highly recommend Dr. Joseph Lee and Diamond Creek Dental to anyone looking for long-term, trustworthy dental care. read more

Dr. Joseph is extremely skilled. I hadn't visited since they moved into the new building because I never really had any dental issues. Recently, one of my implant teeth became swollen, and they were able to schedule me right away--even offering a same-day appointment before they closed. For urgent situations, they really do their best to accommodate you as quickly as possible. Dr. Joseph's technique is still incredibly professional and gentle, and the treatment was done with very minimal pain. His skills are truly outstanding! The front desk staff is also very friendly and welcoming. I've recommended many friends and clients to this clinic, and everyone has had excellent experiences! read more

Diamond Creek Dental - Cosmetic Dentists Near Me - Diamond Bar, California

My family and I have been coming here for years now. We love Dr. Lee and his amazing team. Today, I met Joanna at the front desk. She was very helpful and friendly. Thank you! read more

Based on the owner's response, I must emphasize that the core issue is the lack of informed consent. If I had been told that the decay was extremely deep and that a filling could likely lead to nerve damage or root canal treatment, I would have chosen a different approach. This tooth had never caused any pain prior to treatment. Without being fully informed of the risks, I was not given a fair opportunity to make an appropriate decision. As a result, I have now lost a previously healthy, asymptomatic tooth and suffered both physically and emotionally. It is very disappointing that there was no clear explanation of risks and no evident empathy for the impact this has had on me. read more

The facility is new and is very clean! Teeth cleaning was quick and easy, and the dentist put good care into my teeth. The office staff were very friendly! However, I did feel like they were trying to sell me a lot of unnecessary products for "preventative" and "cosmetic" reasons that I didn't experience with past dentists. read more

Finally changed my dentist for the whole family and what a great choice. Great communication from the staff to the doctor. From start to end everything was explained to us about our dental needs. Thank you again from Diamond Creek Dental. read more

I haven't written a Yelp review in ages--I'm not usually the type. But I had to share my amazing experience with Dr. Lee and his team. I just finished getting a dental implant and I'm still in disbelief--it took less than 15 minutes! Years ago, I had an implant done somewhere else and I remember it being painful and taking forever. Last year, I tried again but the process was so complicated (I was told to drive to another city just to get a CT scan), I didn't bother following through--I'm too busy running a medical spa. Then someone referred me to Dr. Lee--and wow. They have everything in-house: CT scanner, high-tech equipment, and all the latest tools. No running around, no delays. I've never waited more than 5 minutes here. The front office girl is so kind and efficient--she texts and calls to follow up, which I really appreciate. But back to the implant--it honestly took less than 15 minutes, and the best part? Zero pain. I don't totally understand the "Computer Guided Surgery" they used, but right after the procedure I told Dr. Lee, "I think you just did magic!" The whole team was friendly, professional, and made me feel completely at ease. I'm 100% coming back to get my other two implants done--I am gonna tell my friends and med spa clients to come here. Highly, highly recommend! read more

Receptionist answered all confused when I called and said "I'd like to be a new patient". Wouldn't one respond with "oh let's get started with your name". Idk just weird They're booked out until JULY. No cut ins or any offer to be on a cancellation list even when I specified I had teeth pain. read more

The staff is great ... my whole family goes here. So far every experience - front office or doctor - has been excellent

I got my crown three years ago at a dental office in la puente. Ever since, my crown didn't feel too good. My crown was sore most of the time. So then I had checkups at two other different dental offices. They did the x ray, they prescribed rinse, antibiotics and etc. But still, they told me that the crown was perfect, so I was kinda gave up in the end. The soreness is bearable, so I was kinda assuring myself that maybe psychologically I didn't like the crown, and that caused the soreness. Until one day, I knew Joseph through my work. It was just a random chat with Joseph, and he said, you know what, Sky! Just come and I would check the crown for you, don't worry about the money, I will help you. To be honest, I cried when he said that. So I went to his office and Joseph took x ray on my crown, and also he was holding a tiny camera in my mouth taking pictures. Surprisingly, he found a tiny hole under my crown. He told me that the crown wasn't placed correctly despite the fact that the surface of the crown was perfect. Immediately, all of my concerns come to an answer, I cried in tears. I was upset and happy at the same time because I realized all those years, I was living with this stupid crown. I immediately scheduled an appointment with Joseph. Merely two days ago, Joseph just removed my old crown and fixed the cavity that was under the crown. I have no pain now and feeling so grateful that I met Joseph in my life. He was the only dentist that really listens to me and takes good care of my teeth. I highly recommend Joseph, he is the most kind and caring dentist that I have ever met in my life. read more

I have been Dr. Lee's patient for many years. He is a great doctor. I called his office recently and he was all booked for appointments on that day. I told his staff that I had a bump on my gum and I had severe toothache. She talked to the doctor and made an appointment for me to see Dr. Lee on the same day. Thank you so much for being so kind and understanding! read more

Love Doctor Joseph Lee has been a wonderful dentist for all of us in my family. He and his entire staff are very kind and patient, they send us reminders to schedule, and also appointment reminders of our visit. Oh ... his new office ... very nice all around. Lots of windows and good lighting. The staff is very helpful and I love that all of them are bilingual and speak different languages including Spanish, Chinese, and more. Doctor Lee is caring and a good human being all around. read more

I was referred here by my mom and siblings. They all have great experiences at this Dentist and always talk about how friendly Dr. Joseph Lee and his employees are. This is my second time visiting this Dentist and Dr. Joseph Lee has been the best Dentist I have been to, everyone is friendly! He has a nice office. Everything is nice and clean! I had a great experience. This is now my Dentist. read more

Highly recommend this dentist!! I've been going to one close to home for years and I hated it. But my experience here was much different and it was very quick, professional, and enjoyable. The dr is extremely friendly & knowledgeable. I love the x-ray technology they use too. The doctor quickly identified the condition of my teeth and explained everything with photos. AND there's a TV on the ceiling which was amazing to distract myself while they were cleaning my teeth :) Overall, a great experience here! I highly trust this dentist and I recommend coming here read more

Joseph and his team are A+ professional and friendly. Have been coming to him for years and highly recommend him to take care of your teeth. read more

I was having very bad tooth pain under one of my upper crowns. So I called Diamond Creek Dental and was thankfully able to book an appointment the very next morning. Arrived the next day, singed in, and was called in promptly. My dental assistant, Rosie, was very kind and accommodating. I got to turn the TV to The Office which was also on the ceiling during my procedure. I was already feeling much more at ease :) So Dr. Joseph Lee came in shortly after I settled in, and began his diagnosis. He said that there may be one of two outcomes. One was that my crown needed to be shaved down because my bite / constant grind and wear may be what caused the tooth ache, and two was that I may possibly have a root canal issue, for which I'd have to see root canal specialist which would of course be much more costly. So he recommended that he shave down the crown to adjust my bite and see if the discomfort subsided in the next three days. I liked that option! Well, after he was done, biting did not hurt anymore which was amazing. But of course, I still had an achy tooth / nerve. So I will now wait and see if it gets better. But overall, I am so happy that I found Dr. Joseph Lee. He is honest and friendly, and seems to offer the best possible solution that is in the best interest of his patients. I'm truly impressed and I'm so glad they are located in my neighborhood. My husband and I will most definitely be coming back in the future if needed! Thank you to Dr. Lee and his wonderful staff! ** UPDATE ** Unfortunately, my tooth pain persisted, so I called their office and Dr. Lee asked me to come in right away. He said my pain was due to a deeper root canal issue so he referred me to a root canal specialist because he felt they would be able to take care of my problem more confidently and effectively than he could. And I REALLY appreciate Dr. Lee's honesty and referral because as a patient, I want to ensure that whatever procedure I get done, gets done right! So I went to see the root canal specialist and he was able to clear out the infection, no problem! Thank you, Dr. Lee for all your help! I will be coming here from now on for all general dentistry. read more

The team here is attentive and helpful. I live in irvine and I would definitely drive back out here again.

Dr. is an attentive and caring doctor. You can tell he genuinely cares about his patients. He took the time to answer my questions and also explained in detail the reasons for my concerns. He ensured all of my questions were addressed. He also is very honest and does not try to upsell you on work not needed. I've been to dentists that aren't ethical in that sense and try to sell you unnecessary work so they can charge you for it. I trust his recommendations and care fully. His hygienist Lee also was great at teeth cleaning. It wasn't painful and she was very thorough and detailed. Highly recommend!! read more

Joseph has been my dentist for many years. He is my hero! I have had many emergencies and he is always there to help. He responds back immediately and schedules me in right away even on his day off. I am so grateful for him. Definitely the best dentist in town. read more

First of all, I would have contacted you first as an emergency case if patient/clinician relationship was built and trust was formed for a consistent period of time. As a patient, why would I contact you again while an error happened at my first visit, and it's inconvenient to the both sides? Isn't the first impression the foundation of professional trust? I remembered clearly, when I was at Loma Linda U., the professor told the student when the student was performing my filling under the professor's supervision, exactly the same tooth, saying "a small uncomfort/strange feelings will magnify in patient's mouth." Secondly, I was thinking about re-rating your practice to a higher rate because you already messaged me privately, and your staff contacted me with being willing to refund the cost, including not to bill the insurance. I was impressed for doing an honest practice and you showed that you are humble to listen to a patient. Yet, you got defensive and changed your mind, then say it's a full blast on social media? Let's re-rate and give the two stars back to your staff. Sorry if it's hard to be humble and deliver good customer service at your end, doesn't matter how clever you are or what degrees you got. read more

I've been here twice and both times have been really pleasant. I had just switched dental plans and found that this office was in network, so I gave it a shot. Booking was easy, just a phone call and you're set. They also text you to confirm your appointment a few days before, so that's a plus. This office has high reviews for a reason! The office staff and the doctor are all very knowledgeable and patient. They are also super efficient - I was done getting X-rays in less than 5 minutes. And as someone who has always had a hard time with that, I'm surprised how quick it was. (Props to the amazing tech!) After getting my X-rays, the doctor joined in and reviewed the scans for any cavities, issues, etc. It's a fairly short time with the doctor, but I didn't feel like I was missing any information. He is thorough with his review and makes sure to listen to questions/concerns. Since I went for a cleaning, I was helped by the dental hygienist. She's amazing! She's super bubbly and easy to talk to. The cleaning went smooth, no pain or discomfort. There's also a tv on the ceiling, so I was able to distract myself with some dramas! Overall great experience and I would highly recommend giving this office a try! read more

I think Dr. Lee is amazing. I had a crown replaced a few days ago and I have no soreness, no pain and can chew normally on that side. I clearly remember being in discomfort and not being able to really chew properly the first time I had this crown put in by another dentist. Recently, my dad went to see Dr. Lee to have some work done and he had nothing but great things to say about him. Dr. Lee is really honest and practical in his approach to treatment, which my dad and I really appreciate. Staff is helpful and their hygienists are also really good. read more

I haven't gone out of my way to put a Yelp review for years now but Dr. Lee left me with no choice. My mother is in town from out of the country with no insurance in the USA so that's a real scare in and of itself. We recently went to a dentist in Irvine for an evaluation and was told her roots were cracked and required an implant. The quote was generous with discounts for Laguna Beach/Irvine rate (only $1,000 more than a typical implant around $2,500). After days of headaches for myself and a week of mouth-ache for my mom, I thought to search locally for a dentist for better rates or do the extraction to buy time. I reached out to Diamond Creek Dental after having tried several others not finding availability and the fees were quite high. To my surprise, the communication was very straightforward and quoted price were each job was very fair! I went ahead and booked for next morning appointment. Fast forward, we met Dr. Lee and his team. They were courteous and caring. After reviewing the x-rays and poking around, Dr. Lee explained to me there were no cracked roots! Went further to explain what the reason for her pain and also made adjustment to her crown to alleviate the problem. He was skeptical of the first diagnosis and referred me to another specialist that is honest and fair. This experience shown me that Dr. Lee: 1. is knowledgeable and full of integrity. 2. is sincere and wants the best for his new and old patients. 3. did not look to benefit financially from a made up diagnosis and recommended the best route. I want to thank and show appreciation for Dr. Joseph Lee's professionalism and ethical practices. I am a fan and will recommend Dr. Lee and his team to anyone that needs a caring and trustworthy dentist. read more

What can I say! The picture speaks for itself! My son was horsing around on Saturday night, needless to say he chipped is tooth in a bad way. Im thinking oh no he needs a crown at 11 years old... oh my goodness. My son was scared... mom what happens now? I have to go to school like this? He has all these questions that of course i can not answer. I call Dr Lee. Dr Lee says don't worry we'll get through it. Then asks if we wanna come in Sunday? We were SO HAPPY not just because he would see us on a Sunday but because he gave us hope, hope that he cared and everything would be okay!!! I posted pics so you could see his awesome work and the review so you could get an idea of the man that he is! Thank you Dr. Lee we love you!! read more

Dr. Lee is very professional! I had my wisdom teeth pulled here. It was impacted wisdom tooth, so it's very hard to get it out, but he did it quick and no pain. I didn't suffer much pain after the surgery either. HIGHLY RECOMMENDED!!! read more

Dr. Lee cares. His staff cares. I hadn't seen them for several months due to a hip replacement and hardships I am going through; they all remembered every detail making me feel so supported and at ease. Entire staff very personable, professional and work together efficiently. Yes, they are busy because it's clear they want to help as many patients as possible and take urgent cases, but I never have to wait long. I feel so comfortable, welcomed and taken care of here and I highly recommend. If you are in pain, Dr. Lee will go out if his way to help stop the pain, even if that means he come in after hours. Thank you Dr. Lee for making me feel like your top priority; I can tell you enjoy your profession which is also reflected through your staff. I hope you know you have a significant purpose in this life to help others with your expertise and skills. 4 stars for Diamond Creek Dental. read more

Alright.... two and a half years later, 5 cleanings and a scheduled filling in a month, this place has run the gauntlet and gets the 5 stars in my book. What I missed in my first experience, the attention to detail and quantitative analysis of how bad my teeth are, has been compensated by the troves of pictures he accumulates from each visit. It has been neat to see the progression in decline in some areas of my oral health, but also areas where improvements have been made. The quality of the pictures he takes, coupled with his breakdown of pictures from one visit to another, are enough to paint a picture of how things are going in the teeth and gum department. The man and his team work hard, and they are good at what they do. I have not had a negative zero experience at his office which, considering it's a dentist's office, is actually a positive thing when viewed over an almost three year time span. That is my new story, and what I am sticking with read more

Dr Lee is AWESOME and the staff is great. Always focused on patient care and always goes the extra mile. Thanks Dr Lee and team

I don't know anyone that enjoys going to see the dentist, but my experience here came close to that. I hadn't gone to the dentist in nearly 10 years. I've been having pain in my mouth for the past few days where I couldn't sleep. My wife still had to push me to go see a dentist. I chose this place because of the good Yelp reviews, and they were spot on. Excellent staff, and Dr Lee is super professional, courteous, and patient. He explained each step, and made sure I felt comfortable through out my visit. I ended up getting a root canal, and it went super smooth. While you're leaned back in the chair, you can watch one of your favorite shows on Netflix (There's a tv mounted on the ceiling). Definitely coming back for regular visits. Thank you Dr Lee and staff. read more

First time here being new to the area. Accepted new patients and insurance so scheduling was a breeze. I was not used to see that there were no rooms (closed doors), but it still felt very private and didn't bother me. Loved how they used a hand held Gun for X-rays, much easier in collecting images. Dr Lee and his staff were all very patient, precise and got the job done very well! My husband (new patient too) needed to see a dentist the week after, so they were able to squeeze him in the same day we called because of an emergency. Although Dr Lee had to refer him to another dentist to review his case, he acted quickly and prescribed some antibiotics for him in the meantime. Great customer service and looking forward to my next visit! read more

I've been visiting Dr.Lee's office for more than two years so I'm confident to make this review to say Dr. Lee and his staff are great, trustworthy and caring! Very efficient on every appointment and almost no waiting time even they are very busy. Nearly painless process during the treatment, no matter fillings or extraction. My overall dental health is getting better. Also a big thumb up to the front desk girl(sorry I couldn't remember her name), she is awesome and so sweet! read more

Thank you so much Dr. Joseph Lee and Li, the hygienist, for taking excellent care of me today during my visit!! The entire staff was very friendly and the overall environment was welcoming. read more

Courteous, kind and exceptionally knowledgeable in his craft. Thank you for fixing me and fast. I couldn't recommend any dentist more!

I have been afraid of dentists until my tooth ache got really serve...happy that I found a great dentist! Quick Response and Appointment After emailing the office, I received response within couple hours when the office was closed due to COVID-19 and was able to get a next day appointment set up. Clean Environment The office was clean from waiting area to the individual rooms. The staffs there would sanitize everything after used (such as x-ray shield) Friendly staff and professional dentist Dr. Lee Staffs were friendly throughout the visit and my root canal was treated right away. Dr. Lee was very careful and made the treatment pain-free. Less Contact I really like how they take appointments one hour apart during COVID-19 which means patient won't get in contact with other people, only the staffs there and Dr. Lee. read more

Absolutely Amazing! In my desperate call for help for an emergency at 11pm last night, Dr. Lee was the only person to hear me out. He set me up for an appointment the very next morning, and I walked out feeling even better than my previous dental work. Needless to say, his altruism goes hand-in-hand with his professionalism. I 120% recommend this business! read more
