i have brushed my teeth twice a day for years and at 22 i have had 3 root canals. one of the teeth leading to extraction. a few fillings when i was a kid and now 2 wisdoms and another root canal need to come out. people tell me maybe its because i didnt get enough vitamin c or vitamin d as a kid. if i start taking multivitamins will these give me any glimmer of hope in the future to save what teeth i have. its very debilitating and embarresing to me. i cant get myself to be happy anymore because of all these problems.
