Patient Reviews

The feedback we receive from our valued patients is critical to our success

  • I have visited this dental office for cleaning my teeth. The way the office staff & doctor treated me was amazing. And the cleaning process is extremely good and now I feel found my home doctor after years trying with several dentists. Specially equipment, medical process and medications are so good that as a patient my teeth cleaning process was simple, easy and relaxing as simple as watching a movie. I have not faced any sensitivity / ache issues that I generally get with other places. As the place was so good, immediately, I took my wife and two kids. Guess what, the kids like it tooooo. This dental facility rocks!!!!!!

  • Very beautiful office I have seen in a while and very friendly staff. I have always been scared about shots in my gums and never got fillings done due to the fear. I really appreciate Dr Kumar explaining every thing before the procedure. Did not feel a thing during the procedure. I am glad I found this place. Highly recommend him to my friends and family.

  • I have been going here since I moved out of Fremont. Dr Sanjay is one of the finest dentist I have ever known. My first visit was to fix the crown which came off. As soon as I walked through the door, I didn't have to wait too long to see the dentist and once I did he was very welcoming and walked me through what he would be doing that day. He fixed the issue with the crown and also did a complete checkup and give me a detailed report of all the teeth. I visited multiple times for fillings and every time I visit the staff is incredibly professional and friendly, and they always remind me of appointments. My daughter had her  regular dental checkup and cleaning and she loved the care taken by Dr Sanjay and his team. We are happy that we finally found a great dentist. We will be going to Smile Designs Dentistry for all our dental needs.

  • Look no further for your dental needs! I avoided the dentist for 6 long years, not because I was afraid of what my mouth might entail, but because I didn't know a dentist I could trust! Dr. S. And his staff are beyond trustworthy. They are friendly, caring, respectful, and they truly want to help you. Dr. S. explains EVERYTHING! Which I love considering I know nothing about dentistry. Erika at the front desk is great! I appreciate the appointment reminder phone calls because let's be honest... It's very easy to forget you have to go the dentist! And the wonderful dentist assistants (sorry I don't remember your names...) are the best! Although my dental work is complete for now I plan on making Smile Dentistry my dental home (now if only I could convince my husband to go)! 😉

  • I recently had minor issue with teeth I was able to get next day appointment ( staff called me back same day after patient cancellation). Have been  to many dentistry but I would like specially mention reason being Dr. Sanjay before he started treatment explained problems and I have never seen any doctor feeling about my problem as his own and explaining what needs to be done to fix. Staff also explained about what is covered in my insurance plan how much I'll need to pay I really liked overall experience. The office also seemed brand new very clean and loads of equipment. I'll certainly go back and recommend to anyone who prefers doctors who spend time to explain and educate patients.t

  • I visited Dr.Sanjay Kumar's dental office recently for my dental appointment and was extremely pleased with the care I have received.  Dr. Sanjay is very professional, patient, thorough and explained at each step about the procedure. My fillings were done in a sophisticated manner. Dr. Sanjay was very meticulous and thorough.  I got my fillings done on that day as well and very happy with it. I would highly recommend my friends and family to Smile Designs Dentistry.
