i didnt go for a couple of years and was convinced that i had neglected my teeth doe to alcohol, i even said to him before the examination that i would not be surprised to find some problems...at the end of the checkout he said there is nothing wrong with your teeth, they are very strong but how much do you smoke to get such staining on them and continued to clean them for 1 HOUR with his nurse choking i mean helping with her water spray thing, bitch (sorry no other word pays justice to her awfulness at her job) almost drowned me grrrrrr!
