He is overall a great dentist. Wish he can spend a bit more time talking to you before you are seated and prepped for your procedure. I made another appointment for a general check up. Hopefully this appointment we will chat a bit about the overall care of my teeth in the future.

I visited for a new discoloration of a previously existing pit in the surface of a tooth. The dentist reviewed the x-ray and tested the pit with a dental pick, and assured me that there is no evidence of decay. I asked about what sort of changes in this pit should prompt me to be concerned in the future, that it may have progressed to decay, and he basically said dont worry about it. Im a high information person, and would have appreciated more explanation of what is going on, why there is no cause for concern (seriously, I have a hole in the front of my tooth that turned brown--how is this not something to worry about?) at this time.
