I hate the dentist. The sensitivity of my mouth and gums due to an auto accident kept me from the dentist for years. I don't know how I did it. But when a friend of mine told me about her experience with Dr. Thodas and his staff, I was willing to give it a try, with the gas. Now, no gas is required and I have no trepedations whatsoever about going in. I still need quite a bit of numbing, but the care and sensitivity they provide is exceptional. I highly recommend Dr. Thodas and his great staff .
