Q. I have been suffering from sensitive tooth for more than a month. When I visited the dentist he used desensitized product to relieve the symptoms, which did not help. Now today I went again and he took little bit of my old filling and filled it with a new one and also around the sensitive teeth. My question is that I feel my tooth has gone worse do I need to give it time or shell I go back to him again. I tried to brush which was not pleasant.
