    Great view from the dental chair
    Lisa K.

    Highly recommend this place! I was referred here by another dentist because I had to get my wisdom teeth pulled out and had procrastinated on it so the roots were so deep my regular dentist couldn't do it. I'm glad I got it done here. Dr. Lem and his staff were so incredibly nice and thoughtful. I've always been slightly scared to go to the dentist and the whole experience great. Dr. Lem takes the time to walk you through the procedure (even during) so you're never surprised on what's going on. His assistants during the operation were so kind, considerate, and took great care of me. The healing process was not bad at all. I had pain the first day after surgery but the second day onward there was virtually minimal pain and discomfort. Bonus - rather than boring white walls, the view while you're waiting and getting your teeth done is awesome!

    Dr. Lem removed a cracked tooth for me & installed a titanium implant last year. I felt very little pain, he uses the latest technology, his work is impeccable, and his staff is kind. Everybody is very competent. The front office is pretty persistent with reminding you about your appointments, but if you're a procrastinator like me, it was a benefit Since installing the crown over the implant, I've had zero problems & don't even notice it's not my own tooth. This was my first implant & Dr. Lem & his office did a great job explaining everything and putting me at ease. I recommend his office to my friends & coworkers without hesitation

    I'm surprised at all the negative reviews on here for Dr. Lem. I was referred to Dr. Lem by my dentist since I had to remove a wisdom tooth out. I remember the nurse telling me that this would be the best nap I've ever had. The next thing I remember was waking up and seeing the nurse next to me. I asked her when were we going to get started and she informed me the procedure had already been done. It was indeed the best nap I've ever had. I think Dr. Lem did a great job because I didn't swell up nor was I in any pain what so ever. I returned back a week later for a check up and everything was great. I was back to eating solid food and using mouth wash again. Yay! I'll admit the procedure was a bit costly. I paid cash and spent a little under $800 for 1 wisdom tooth. They told me mine costed more because of how impacted it was and not to mention I was put to sleep. Best decision ever! since I don't endure pain well. They do accept credit cards but will give you a discount if you agree to pay in cash. They have a parking lot that they share with other offices so at times it maybe difficult to find a parking spot.

He is usually very scared of doctor visits and even the word "surgery," but Dr. Lee and the whole team were amazing with him. They explained everything in a simple way he could understand and made him feel comfortable. For the first time, he walked into the surgery room with them without being scared or looking back at me. Dr. Lee, Kristy, Robert, and the whole team are very professional and experienced with kids. As parents, we felt very relieved and confident in their care. Highly recommend to any family looking for a skilled and compassionate oral surgery practice.

At the consultation, Dr. Lee treated our daughter with so much caring and respect. She explained the procedure thoroughly and made my daughter feel at ease. During the day of the procedure, we found out that an additional extraction (in addition to the wisdom teeth) was needed. The doctor was able to handle that and kept us apprised of everything. After care instructions were in depth (in a good way). Dr. Lee even followed up when we got home after the surgery to make sure everything was ok. Also a huge kudos to Dr. Lee's staff. I wish all visits to a doctor's office went this well.

    As someone who dreaded the dentist and suddenly woke up one morning with wiggling teeth, I was…read morecompletely dreading the dentist. I had originally been seeing another dentist in Glendora for my wiggling teeth and a bunch of cavities I needed done but the more I went to the other dentist, the more I felt like I needed a better dentist because my concerns weren't being addressed. I was referred here by a friend of mine and although I was anxious making the first call to get my firs appointment, I was immediately greeted by a nice and empathetic receptionist who listened to me about my previous dental experiences and why I needed a new dentist. She set me up right away and I was in the door that same week. I had my third visit today and I genuinely cannot say how much I love this place, the staff, the procedures, and the way they educate their patients. They've done an exam, two of my fillings (which were WAY better and faster than my previous dentist), and even helped me get a night guard due to my terrible grinding. Today, Liz and Jessica were able to help address my wiggling teeth more and educated me on how to prevent and treat what was going on. They truly cared about me, went out of their way to educate me, and honestly just went above and beyond for me during my cleaning. I was even super confident in the intern dental assistant, Samantha, that was helping the dentist today because I knew I was in good hands. I cannot recommend this place enough. I've sent my brother here and will continue to send everyone I know here. Cannot say enough good stuff about the staff and office. Worth every penny!

    Beware! Extremely disappointed with the work done here for a crown…read more Initially when I had the temporarily crown put on, the bite was off and Dr. Desai shaved a significant portion off which caused my tooth to become extremely sensitive to a point where I cannot eat from one side of my mouth. Once the actual crown came, I should've known something was off when he spent a good amount of time shaving and adjusting the crown and opposing teeth. After the crown was put on, now both my crown and opposing teeth is extremely sensitive to temperature and I am experiencing pain from chewing. When I brought my concerns to Dr. Desai he stated everything looks fine and the pain should go away over time. I decided to go to another Dentist for a second opinion and his diagnosis was that the crown was oversized and it needs a replacement. He performed a series of bite test and he showed me which spots were higher than the others. Also you can visibly see that the crown was entirely flat on top due to all the shaving he performed on an oversized crown. Dr. Desai should have known that the measurements were wrong when the temporary cap did not fit. But instead of remeasuring the tooth and reordering the right sized crown, he decided that flatting the entire top side of the crown will do the trick. Initially his front desk staff was extremely responsive but after asking for a copy of the receipt and pictures of the x-rays, their response was are "extremely busy" and will try to email me the next morning. Next morning came, still no email.

He also helped save her money while still providing outstanding care. Even though he is young, his skills, professionalism, and attention to detail are truly impressive. You can tell he genuinely cares about his patients and takes pride in his work. He must have inherited every perfection from his father, Dr. Antoine -- the dedication, precision, and passion for excellent dental work truly show. The entire implant process was almost pain free with very minimal discomfort. The specially designed crowns gave her the best bite and her recovery was fast because of the excellent care and detailed follow-up from Dr. Sayegh. The staff are always kind, patient, and welcoming, and the office is beautiful, clean, and professional. We are extremely grateful for the care she received.
