Glenn Belen, DDS

Dr. Belen and entire staff are very professional and caring.
The staff is knowledgeable and keeps you informed about your dental recommendations and needs. The doctor spent time explaining the health of my teeth and what were areas of concern. I appreciate that he explained the treatment options and taking in consideration my own concerns we were able to make plan for my dental care.
Top of the line office with amazing technology, the office in general its very spacious with big treatment rooms. Lovely music always playing, and during treatment I got a set of headphones which helped me calm down.
The hygienists gives you a goodie bag with brush, floss and toothpaste and they also have additional goodie bags in the bathroom, (i have to admit i did take an additional ;) bag once)
P.S
I love that they txt, to remind/​confirm of upcoming appointments

My wife and I have been longtime patients of San Mateo Dental Center (and of numerous other dental services over the years) and feel that SMDC is the very best we’ve experienced. I had several implants a couple years ago and could not have been happier. During the procedure Dr. Belen showed me the x-​rays he was using to check the alignment of the implant sockets, and the precision and skill of his work was clearly apparent. We have had numerous cleanings and other work done by SMDC and always find Dr. Belen, Emy, Erika, Christy and the rest of the staff to be respective of our time, highly skilled, and genuinely friendly.

My mom and I have been coming to Dr. Belen for over 25 years! We were with him in his San Francisco office, and since the move have made the trek down to San Mateo to spend time with our favorite man. (Keep in mind we live in Berkeley!) Dr. Belen and his team are so friendly and funnny that we just can’t stay away!

After a triple (yeah, triple) root canal/​crown session yesterday that was a 5.5 hour date with these folks, I can tell you, that they rock.
This is not my first trip to Dr. Belen and his amazingly good staff — I went years ago in a mess after a horrible dental experience at a «spa» dentist in sf — and Dr. Belen made it right. Incredibly. But years commenced with no insurance and no bucks.
I’m anticipating a couple more visits to get things up to snuff, but yesterday was a much feared trip — they called before, they reduced the patients scheduled to have enough folks for me, they coached, they made all the right calls about music, about meds, before and after.
Today I’m sore, still a little swollen, but you know, if you can say getting these kinds of things done can be … really ok, painless, reassuring… Dr. Belen and his Team — this is the place.
PS Got a call from Dr. Belen himself to make sure things were ok after the procedure/​getting home. How many folks on your care team do that? Yikes!

Don’t believe the good reviews. They are fake. This was my worst dental experience ever!
1. He told me I needed 6 crowns. After he messed up the first two, I changed dentists. The new dentist said I didn’t need any crowns. I didn’t even have cavities.
2. The two crowns he put in were a nightmare! They were obviously made the wrong size. Even after I pointed this out, he spent several hours forcing them into my mouth. One popped out on its own. The other had to be sawed out. YES! I wrote SAWED OUT! He completely destroyed my teeth.
3. The second set of crowns were not much better. He forced them into my mouth. Told me the pain in my other teeth would subside in a few days. It actually took several months. I still get intermittent pain.
4. After getting the two miserable crowns, my teeth were misaligned. His solution was to file down my natural teeth to match his botched up fake ones.
OMG! Two years later, I’m still having daily trouble with his crowns and the neighboring teeth.

Glen Belen is a great dentist. He and his team are very nice people, He has an up-​to-​date practice and really cares about his patients.

BEST DENTIST EVER… Everyone at the office is always very nice, they are a family there and treat you as one to. Dr Belen always goes above and beyond great. He takes the best care of you. He is does not miss a beat. I have had a few dentist in my days, they always come up short until Dr Belen, he is a keeper. I use to hate going to the dentist but not any more.

Stay Away ! His Bently parked in back should have been a sign. He’s nothing more than a con man. He suggested all very expensive unnessesary work.
He wanted to replace old mercury fillings with new mercury fillings. Why? He wanted to replace a fixed bridge with a partial plate. Why? He said I had «the beginnings» of four cavities. The beginnings? Him and his assistant tried selling me a mouth guard to prevent grinding my teeth at night. I don’t or never have ground my teeth and told them 3X «No. I won’t wear that.»
The worst part, he had no dental hygienist and an associate dentist didn’t do an appropriate cleaning. She flossed my teeth and did no scraping. Done in 5 minutes.
This was absolutely the worst dental experience in 30 yrs. I do not lie, cheat or steal. It would be great if everyone followed The Four Agreements rather than pure financial gain.
Again. Go elsewhere. His only care is $$$ and his Bently.

Best dentist I have ever had! Glenn Belen is so gentle and fast. He has all the cool up to date dentistry tool! I highly recommend Glenn!

I required an invasive procedure that needed three visits to complete. I am updating my review (again) as of the second visit of those three.
…STILL FIVE STARS!
Dr. Belen goes *WAY* above and beyond what I believe to be standard care in order to ensure your safety and health. I am under the complete impression that he really wants his patients to have EXCELLENT outcomes no matter what.
In my time of duress, the doctor and his team worked together to ensure I got high quality care. I needed a lot of help, and this team provided me with more than I expected. I am SO grateful I chose Dr. Belen and his staff.
— He pays attention to details, and customizes treatment for your condition (s).
— The facility is impeccably clean
— The entire staff is highly trained and talented.
— The team is very patient, kind, and respectful of needs.
— They call you, email you, work with you, per your needs.
— The bonus is that they are nice, too.
— My teeth look great.
Its rare to find businesses that care more about customer well-​being than about themselves. I think we as a community should support these kinds of businesses.
I trust Dr. Belen and have recommended him to my friends and family. I extend this recommendation to you as well. Be open and honest with him, and you too will have a great experience.
I look forward to my future visits to Dr. Belen, and to ever-​better oral health thanks to his guidance and efforts.

Dr. Belen charged twice than other dentist I had before for the same treatment. He is not very kind, in my opinion. He said my teeth is ugly. I felt embarrassed and a little humiliated after I left the office.

I am very pleased with my dental implant that Dr Belen performed. I have also had a considerable amount of work done without any problems. My Invisalign is still in progress but I am so happy that my bottom front teeth are no longer overlapping as they once were.

This is my new dentist! Everyone there is super welcoming and really informative. Angela even held my hand will my cavity was filled. They also gave me headphones to listen to so I would hear the drill. They are also really accommodating and rearranged their schedule to fit in my filling because of time restraints on my part. I was 20 mins late due to traffic (ppl can’t drive in the rain in northern cali) and they didn’t give me any attitude, just understanding. I liked that everything was explained to me throughly and proof was provided as to why I needed fillings. It also needs to be said that the office is super clean and stunning. Even the bathroom has marble lol. I will totally recommend this place to anyone! (Excuse typos, this is being written on my phone)
The only suggestion I would give is to hire a pediatric dentist so my 14 month old could go there too.

Dr. Belen and his staff are wonderful! The office has state of the art equipment and is very clean. Dr. Belen does great work and takes time in explaining what he’s doing. I had a root canal done and it was painless! I recommend going to Dr. Belen for any of your dental needs.

Dr. Belen and his team truly care about each of their patients. I’ve been to many dentists over the years, and can honestly say that I’ve never had such a welcoming experience. He and his team put a tremendous amount of care into making sure that patients walk out of the office with all dental problems fixed. The office uses state of the art technology and Dr. Belen walks you through the entire procedure using that technology. One of the best dentists in the Bay Area! Would definitely recommend to see him!

The most thorough dental exam I’ve ever had, certainly one of the most personable doctors I’ve ever had and the nicest staff ever. Janice, the dental hygienist was so nice and gentle — I’m actually looking forward to going back: D I am super happy to have discovered Dr. Belen and his team. Highly recommend.

Just started Invisalign program five weeks ago. It’s not as bad as I thought it would be. The measuring of my teeth took the longest, I’m very pleased with the attention and care I’m receiving on the adjustment appointments. I’ll keep you up to date.

First off, I will preface by saying I have terrible dental phobia and that this review is a long time coming.
I first went to Dr. Belen’s office for a cleaning, and had a perfectly pleasant, pain-​free experience with the hygienist, Lisa. I liked her so much, we discussed how I could have her again as my hygienist in 6 months.
6 months later. I get a phone call from the receptionist on a Saturday asking me to move my appointment one hour earlier, because they had a cancellation. I say OK. I go in, Friday morning at 10am, and wait for 25 minutes because the staff was having a «meeting». I suppose giggling, laughing, and talking in the back room counts as a meeting.
Finally, I get called in (and I am the only patient there), and get a completely random hygienist. I ask for Lisa, and not only does nobody know where she is, but she has never worked there and they don’t know who I’m talking about. What? This is six months later, not six years, I’m sure at least ONE person there knows who this woman is!
I proceed to experience THE most rough cleaning I have ever had. The hygienist wouldn’t shut up about teeth and cleaning and hygiene, although I asked her several times over to talk about anything else but because it made me nervous. She also told me that I had gum disease, which I didn’t have (as confirmed with an actual dentist), and that I needed invisalign Wow.
At the end, she made me watch an instructional video on brushing your teeth, which I found to be completely insulting. I also left with a sore mouth and bleeding gums all around. Absolutely terrible.
When I first came here, my mouth was a disaster. Dr Cheung went over all the information with me, though honestly, it was truly bizarre to be shown x-​rays, photographs, and charts proving how screwed up your mouth is. I switched dentists right after my 2^nd cleaning appointment, and I am so glad I did.
I will say that Dr. Belen’s office is very clean and SOME of his staff members are extremely friendly. I hardly spoke with Dr. Belen or Dr. Cheung, but Dr. Vasco seemed very kind. But please guys, please stop making your patients feel terrible and ashamed for the condition of their mouths! I don’t need to be scolded like I’m a child, seriously!

Best dentist I’ve been to! I’m not usually a big fan of the dentist (I’ve had tons of bad experiences elsewhere) but everyone here is super nice and very accommodating. I hadn’t been in for a while after my first time here, and when I walked, in they greeted me by name and told me that they’d be ready to take me back shortly. Mind you I was a little early but they still took me back within a few short minutes.
I would definitely recommend this place and I surely will be going to the dentist more often.

I found Dr. Belen trhough 1−800-Dentist. I didn’t realize how much work my teeth needed. Dr. Belen has state of the art equipment, small cameras to check each tooth. He took the time to explain everything that needed to be done immediately and what could be done in 2014. I appreciated his honestly and the hard work he has put into my teeth already. His dental assistants have been kind and helpful.
My mother has also since gone to Dr. Belen. She was very impressed by him as well.
Dr. Belen has a long-​term client in me!!!
