i just had a baby 5 weeks ago and i know that has alot of effect on your teeth. ive always had sensitive teeth but since i had her my teeth have become so sensitive it hurts for even toothpaste to touch them! is there anyway to fix this problem without going to my dentist and what could cause this sudden sensitviity? i've never had a cavity but i am also wondering if i could have some now and if that would cause this?
