Advanced Dental Care of Silicon Valley

I chose this office because of the positive Unilocal reviews. What a mistake!
The filling Dr. Thomas did fell out a couple of months after he did it.
When I called the office the receptionist was unable to answer the simplest questions and when I asked if I would have to pay again for the filling that fell out the receptionist quickly transferred me to the office manager. This woman was extremely rude and aggressive to the point where I asked for my X-​ray to be forwarded to me because I was going to go somewhere else. They took two weeks from my initial request to email me an X-​ray. I have the emails to prove it. I ended up having to pay for new X-​rays because Dr. Thomas’ office refused to email me the X-​rays I’d already paid for before I had to get the tooth refilled.
So poor dental work, uninformed reception and insanely rude office manager.
I’m not sure why there were so many positive reviews before but don’t get fooled like I did.

Stay away from this place (now called Advanced Dental Care of Silicon Valley). I experienced over a year of pain since starting treatment with Dr. Thomas. I found him through Unilocal (he had better reviews back then, I guess) and went for a routine cleaning and check-​up. After that, I spent hours and hours, days and days in his office while he «fixed» the problems that he diagnosed. Two root canals and two crowns later, my mouth is still not right. There were a number of issues along the way, including crowns not fitting and my bite needing to be adjusted countless times. I have since gone to another dentist who addressed most of these problems in just one visit.
You can see in my x-​rays that the crowns Dr. Thomas put on do NOT fit right! It doesn’t take a dentist to see that. Crowns are supposed to fit snug against the remaining tooth, and there should be no overhang. I will have to have these replaced sooner rather than later — but no way am I trusting Thomas to do that work, especially because this is already the second set of crowns he had to put on my teeth. In addition, my new dentist said that Thomas used a very low-​quality material on these crowns. So much so that once my bite was finally corrected, the metal on the crown is now showing through. Which, cosmetically, is an issue that can only be addressed through a replacement.
Dr. Thomas has irreversibly ruined my teeth. The whole experience was/​still is extremely upsetting, as I have spent a lot of money and am still having problems. After putting up a fight and showing him my new x-​rays that show how poorly done the crowns were, he did refund me the money I paid out-​of-​pocket for the crowns. While I appreciated that give-​back, I would have preferred to have never let him in my mouth in the first place. Stay away!

I went in to have Zoom Teeth Whitening done yesterday. The results are absolutely amazing and pain free! My teeth are whiter that I thought they would be. My confidence level has improved 100%, all I want to do is smile and show my pearly whites. Wonderful experience as always. Thank you.

I was so excited with this dentist — the office, the staff, everything seemed perfect.
Then my nightmare began.
I can only warn you to please get a second opinion for any ‘preventative’ treatments they recommend. I had all of my amalgam fillings replaced, because I was told if I didn’t I would end up needing massive dental work when they broke down. I was taken through an hour long doctor to patient explanation of how fillings (that didn’t hurt or bother me in any way) were destroying me teeth — with X-​rays to ‘prove’ it. I have since had a doctor caused abscess (excruciating pain), had to have a filling redone after three months because it cracked, a root canal, a crown, and now I can only chew on one side of my mouth because if any hot or cold touch my ‘new’ fillings the pain is excruciating. If this is preventative medicine — it is unstable and fails in every way. Please be careful when looking for a dentist — do not choose one desperate to rob you of your hard earned money only to slap unstable fillings in your mouth, leaving you with pain and fake teeth.
After the filling which caused my abscess — I was in almost immediate excruciating pain. When I called the office they told me they couldn’t see me for a few days. I was in the process of moving, but after the pain grew to unbearable heights, I was finally scheduled an emergency appointment that I would have to drive four hours to attend. I was told not to find a new local dentist in my new area, but to come back to Dr Thomas. He prescribed me Motrin. When I called a few hours later because the pain was so intense he didn’t answer or return the call from his emergency line. I was taken to the ER where I was prescribed a high dose pain reliever. I had to find childcare and a driver to take me eight hours round trip. The pain medication left me loopy and unable to stay awake. When I arrived Dr thomas confirmed the abscess and bacteria infection from his work, but was too busy to take care of fixing what he had done to my mouth. He packed me with a sedative in my tooth, prescribed an antibiotic, and told me to find a dentist in my new area to fix my teeth. I have since been constantly at the dentist having my ‘preventative’ fillings replaced and redone. I have spent thousands of dollars repairing my mouth from the treatment plan Dr Thomas recommended. This in no way takes in to account the pain and suffering I have endured.
Please do NOT use this dentist. They are nice and present a great front, but the reality is not as pretty a picture.

Dr. Thomas and his crew are really the best! They’re friendly, knowledgeable and great at what they do. They got me started on Invisalign and my teeth are really nice and straight for once! My kids and grandkids like them too. I enjoy my visits to the dentist again. They’re the best!

I have been going to Dr. Thomas for 20 years now. I have had a tremendous amount of work done. I have never had to even take a pain pill after a procedure.
I have always had an excellent experience. I agree with all of the positive reviews. Everyone in his office is extremely professional, very caring and very gentle.
I would recommend Dr. Thomas highly!!!

We are new to the area and were looking for a good family dentist. We found Dr. Thomas through our insurance and we couldn’t be happier! The entire team is friendly and professional. They take the time to get to know each patient and provide an exceptional level of care!

I really wanted straight white teeth, so I could smile big. Dr. Thomas fixed my smile right in only 2 appointments! And there was no pain at all!

My wife and I have been going to Dr. Thomas for many years. We have found his work to be excellent and the office people to be very helpful.

If I could give this place negative stars I would. My husband and I went on two separate days a couple of years ago as we had moved to Santa Clara and our dentist in Millbrae was too far. Before he even looked at either of our teeth he sat us in a small room and went over periodontal disease. This took an hour and then he put us in a chair and surprise, we both have periodontal disease. We were both mid 20s at the time. He then set us up with 3 appts each for deep root cleaning, which isn’t covered by insurance and would be several hundred dollars. I made the appts and then canceled then later. I told them that we were not interested in getting deep root cleaning. They sent each of us a letter stating that basically we are not taking care of our teeth and that the consequences would be horrible. The letters ended with something about God and finding him. Later, I went back to Millbrae to our previous dentist and they laughed and said that our teeth were completely healthy. Also, I called to request the x-​ray that they did because it was one of those full head ones that you only get once every couple of years. They charged me $ 90 just to mail it.

Went to Dr. Thomas a few years ago ’cause I broke a tooth, turns out it needed a root canal. The procedure was fairly painful and I was uncomfortable much of the time. My new dentist pointed out that the crown Dr. Thomas made juts over the molar and Dr. Thomas left too much space between the crown and the neighboring tooth, leaving a gap (that caused a cavity, luckily my new dentist closed in the space with the new filling.)
A real hatchet-​job, overall, and Dr. Thomas didn’t even address my other dental issues with me. (I had no dental coverage, nor a regular dentist, for many years.)
All that, and I had to endure bad Christian music over the office sound system. Pass!
