I'm not really content with my own teeth. I never did take care of to when I was younger I'm 25 now and nobody can tell but I feel like my teeth are too sensitive just had some fillings put in the 3 weeks ago and it hurts like a mother! I hope I don't need a root canal in every one of them? Also, I had a tooth chipped from the inside close to the gumline. (Not one of the fillings) It bothers now & im always playing with the crack. I'm not sure if it was because I had so much tartar there or what. But I always brush and floss everyday and I'm starting to go the dentist often. Is there anything I could do or does diet have anything to do with teeth? How do I keep my teeth healthier and stronger? Help please . .
