I recently moved to the area and am a new patient of Dr. Mohammed. From the first moment I stepped into the office, to the time I walked out it was an exceptional experience -- which is normally not something you say about going to the dentist. Dr. Mohammed and the entire staff are absolutely wonderful. What really impressed me is the time Dr. Mohammed took to explain everything I had questions about. The facilities are also top notch. The technology they have is cool since you can see what Dr. Mohammed is looking at while you are in the chair. Highly recommend Dr. Mohammed and his staff!!!!! read more

I saw Dr. Tseng for many years and still think he's a great guy and usually a good dentist, but I sadly have to update my previous 5-star review. The biggest problem is that I paid thousands of dollars for two crowns which caused gum bleeding and one of the teeth needed a root canal shortly after the crown was placed. I went to a second well-regarded dentist who told me the crowns were defective and should be replaced. He wrote a letter to Dr. Tseng describing the flaws and including x-ray evidence. Dr. Tseng didn't think the problems were all that bad and said I would need to pay all over again to replace the crowns (both were less than 2 years old). I ended up paying the new dentist $3,005 to replace both crowns. There were other problems with this dental office too, but they were minor compared to the faulty crowns which cost me so much. read more

This is your new dentist. End of story. We'll skip the part where for 26 years I have hated the dentist and this man changed my mind about the whole industry and skip how awesome he is. Despite never having any contact with me before, when I called them and explained I was in serious pain from my wisdom teeth coming in, they arranged to see me that day so I could be diagnosed and transferred to an oral surgeon promptly. Upon arriving I was promptly and courteously greeted by the staff, and then given x-rays. The technician (apologies if I did not get her title right) proudly explained how their technology exposes me to 80% less radiation than normal xrays, and when I asked if that number summed up to about 55% of the normal radiation or 20% of the normal radiation, she admitted she didn't know and said she would ask and tell me next time I visited. I love medical professionals who admit when they do not know an answer. It makes all of the other answers they give that much more trustworthy. The xrays did not take long, and Dr. Tseng arrived shortly thereafter. I was walked through everything in a logical manner and my options were clearly explained. For the first time, I felt I was being invited to enter a discussion about my dental health and treated like I was an intelligent adult who just didn't happen to know anything about the domain of teeth. I was shown pictures of concern areas and invited to hold a mirror and participate in the discussion, so that I would understand what was happening with my teeth and how to properly care for them. In order to alleviate the pain, Dr. Tseng cleaned the area around the tooth which was coming through, and then taught me how to prepare and care for the tooth until I could go to surgery. This included a syringe and making homemade cleaning solutions and things to help reduce swelling. Since we had a chance, he also checked me over for cavities and explained simple measures on how I could improve my oral health. This man is not drill-happy, and was honest with me that my previous dentist perhaps had been. I had called complaining of pain at 3:15PM and my appointment was at 4PM. I left the office before 5PM. The pain was completely gone, and they had not given me any drugs. I had been literally seeing cross-eyed previously that day from pain. It was explained that the pain would probably return within a week and that I will still need to see an oral surgeon ASAP. They explained my care options, gave me the name of the oral surgeon who works on Dr. Tseng's family, and offered to review a list of oral surgeons covered by my HMO to help me select the best one. This is all despite the fact that Dr. Tseng is not in my HMO network and so they had no expectation to ever have me as an ongoing patient: they are just nice. As Dr. Tseng is not in my HMO's network, I will be canceling my current dental insurance policy and buying a new one with him in network. That is how much I like this dentist, his staff, and his practice. I have never been so excited about a dentist, and for the first time, I will not be dreading my next appointment. They are accepting new patients, despite what the (only) 1-star review (which is also right now the only non-5-star review) says. Hopefully my review has convinced you to go to him. It is the least I can do after how much he helped me. read more

I LOVE this dentist. He is so friendly and warm, as are the other staff members in the office. I have never been so happy to see a dentist in my life, and if I have a cavity, I can't say I mind going back. His office is very close to my house and one day my tooth broke in half while I was eating a taco. I didn't know where to go because I just moved here. I just walked in the office and asked for help. He stopped everything to have a look and make sure I wasn't exposing any nerves and stayed after hours the next day to begin to fix the tooth. I have recommended his office to several friends and they all say the same thing, "I can't wait to go back to the dentist". They also do have good music, it can be a classical song and the next minute it is The Cure. Fun! read more

I was in Palo Alto for a course at Stanford. Dr. Tseng was wonderful in assisting with the adjustment of my implant. He worked with my dentist from NYC and helped secure it as I was staying on the west coast another week. Thank you! read more

Dr. Tseng and his staff are professional and extremely friendly. I was always a white-knuckled patient with dentists, but no longer. There is no pain with procedures and in fact, when there is drilling or other stuff going on, you have the option of watching movies. read more

I had a dental emergency yesterday morning and could not get in with my regular dentist, Northern Dental in Santa Clara (who is a nightmare to deal with by the way!). I quickly searched for someplace close to my work in Palo Alto and luckily found Dr. Tseng's office. They not only took me in immediately, they were so nice and about it. The difference between this place and Northern Dental is like night and day! They were friendly, polite, intelligent, accommodating, and caring. Even though I'm not a regular patient I will be now, and I highly recommend this office. read more

I have been going to Dr. Tseng since elementary school. While I don't get toys for going to the dentist now, I still find it a vastly superior experience to other dentists that I've gone to before moving back to the area. His daughter also recently joined the practice and is also fantastic. read more

Dr Tseng and his team are fantastic on every level. No other dentist compares. Never any pain, very gentle hands and supported by all the latest technology and entertainment. Delightful, helpful, accommodating - that's not just Dr. T but everyone at the office. I honestly look forward to my visits. read more

Such a nice dentist! Everyone here is so friendly and efficient. Today I watched a movie while I got a filling. And it was all painless and simple. I also love that he shows you with a camera what your teeth look like, how your tooth compares to fillings, etc. I like being informed. They also give out great toothbrushes. read more

I've been coming here for over 4 years and the service is so consistently good. The hygienists are great. She told me the correct way to brush my teeth after my previous dentist had instructed me wrongly. I fully recommend Dr. Tseng. read more

Dr. Tseng is just what I was looking for in a dentist. Being new to the area, I looked around, and took the advice of Yelp on this one, and am very satisfied. Everyone in the office is friendly, the dental work was easy and comfortable, and I'm happy to have found my new Dentist. read more

Dr. Ray Mohammed is a truly gifted dentist. His state-of-the-art practice will have you wowed. He is extremely thorough and always makes time for his patients, even working weekends when necessary. If you're looking for the best that Palo Alto has to offer, look no further. read more

Been a customer at Dr. Tseng's for years. Great service, great dentists; they give proper advice and are as friendly as it gets. Would certainly recommend! read more

I just met With Dr. Tseng. I had been to a different dentist who had recommended I replace my bridge, put in 3 or 4 crowns, replace many old fillings and do root planing. Over $10, I'm sure. Dr. Tseng looked very carefully, politely and thoroughly through my mouth and concluded I only needed a fluoride treatment on my teeth and some flouride brushing gel. Both were included in the very reasonable exam fee. He said he would keep an eye on a couple spots in my teeth, but nothing needed immediate attention. Every one I met in his office was a complete joy to deal with. I think his reputation of being an excellent dentist who is conservative in his approach is very true. I'm sticking with him! read more

Wow-- great experience. I recently moved here and didn't have a dentist in the area when I chipped a tooth. After reading Yelp reviews, I called Dr. Tseng's office, who found me an appointment time the next day. The entire staff was friendly and knowledgeable, and they use the latest technology. E.g., I got to see live video of the inside of my mouth! Although Dr. Tseng was extremely busy, he took the time to calmly and kindly explain options for dealing with my chipped tooth and the associated pain. I left the office feeling much better. I'll definitely be using him as my regular dentist. read more

This dentist and his employees are superb, and economical. From the moment you open the door you get great, friendly service. Background: I live in Utah and had serious teeth problems that I was informed would cost over $30,000 to fix. Now dental costs in Utah are generally a lot lower in Utah than in Palo Alto, California. But not this time! I checked with Dr Gregory Tseng, a dentist in Palo Alto trusted by my family. Dr. Tseng did the job(6 crowns) for less than $10,000! He and his assistant, Gail, did a beautiful job. My teeth look much nicer, and quite realistic. Dr. Tseng and Gail are incredibly experienced and skillful, as well as goodnatured and kindly. Dr. Tseng should be famous! read more

Dr. Tseng and his team are the best! I had avoided going back to the dentist for a while, and had a previous experience with another dentist office in town that aggressively recommended major work that it turns out I didn't really need. I am so glad that I found Dr. Tseng! They are focused on health, not on cosmetics, an approach that I greatly appreciate. He has a great sense of humor, and really puts you at ease. Cindy, my hygienist, is fantastic. Skilled, empathetic, and just a really nice person. I can't say enough good things about this practice. read more

This is the most well-organized, friendly and efficient physician's practice I have seen. Dr Tseng is very competent; unlike many dentist who you see for the first time, he does not try to re-do everything which was done before. He takes a good look, makes sure to look at the dental records, and works with you to find the best approach. All of his office staff has been exceptionally friendly, professional and courteous. read more

I was a patient of Dr. Tseng's all throughout my high school and college years. When I finally moved away from the area, I lamented my loss and my dental care was never quite the same. I missed Dr. Tseng so much, that I'm now seeing him when I fly back to visit my family. I haven't been able to find a dentist in all of NYC that is as professional, caring and friendly as Dr. Tseng (that goes for his entire office too)! read more

I've been going to this office for 5+ years. It's always been a very positive experience. Dr Tseng is great. He is thorough and gives you the feedback that you need without being an alarmist or trying to sell you all kinds of additional services. Heather is the hygienist that I go to and she is absolutely great. Very gentle, considerate, and does a thorough job. read more

Simply the best! Great staff, great oral hygienists, and if anything ever happens, Dr. Tseng will take care of your teeth unlike any other dentist in town. Highly recommended to anyone who is looking for only the best. read more

What I really like about Dr. Tseng is that his approach is not to touch your teeth (in terms of fillings, drilling, etc.) unless it's absolutely necessary. In addition, I appreciate that he takes the time to explain everything, and is happy to talk about the pros and cons of every option. All of this gives me the utmost confidence in his recommendations, so that's why I'm happy putting my dental health in his hands. read more

I've seen Dr. Tseng ever since I was a young girl. His friendly demeanor hasn't changed over the years and I'm going to miss him and everyone else who works there as I no longer live in the Bay Area. Even when dealing with cavities and cleanings, everyone is always so kind and friendly and I've had some of the best conversations while at their office. (Yes, even with dental appliances in my mouth.) They also have the funniest/cutest holiday cards each year which was a big highlight for me when I was younger. Love them!! read more

We are complete groupies of this office. I have been going for eighteen years and my two teenage sons now go, and they look forward to it. It's like getting together with family. Thank you, Dr. Tseng and staff. read more

I went to Dr. Gregory W. Tseng at the end of 2010 following all the good Yelp reviews and boy do I regret it! I needed to have the following done: 2 root canals, for which I was referred to an ondodontist, and 3 crowns (2 crowns for the RC and a gold crown for another tooth). I paid all this a small fortune as it was to be expected. What I was also expecting was that the crowns and the dental work would have lasted a little longer. From then until now I had to replace one of the RC crown because it fit poorly. There was a bad smell coming out of it, no matter how much I flossed, brushed and cleaned. Once it was removed (by another dentist) I was told there was a cavity that needed to be addressed and that the crown was too big to begin with and not fixed properly. Bacteria seeped through and created a big mess. I had to recently replace the gold crown as well. Back then I chose gold because I was sure it would have served me well for a long time. Imagine my disappointment when they had to cut it into 2 pieces to remove it! The new dentist told me it did not cover the tooth completely leaving it exposed to food and bacteria. There was a big cavity under it that, after removal, left my tooth extremely sensitive and on the verge of an irreversible pulpitis. Now I am waiting to see if I need a root canal. I understand that crowns are not forever, but I have a couple in my mouth that go back to when I was a teenager and they never gave me any troubles. I do take care of my teeth (flossing, brushing, Waterpik, night guard, the whole nine yards) and this should have not happened. So far almost all the work that he did is not holding up to the test of time. He is a nice doctor to deal with, very positive and with good manners and so are his assistants and the rest of the staff. The videos you get to see when dealing with long procedures are also cool, but for me it simply did not work out as I expected. read more
