A few weeks ago i noticed a small hole in one of my back teeth now it is huge . I am sh*t scared of the dentist (i would rather go through the pain of giving birth than sit in a dentist chair). It doesn't hurt at all, what will happen if i don't go to the dentist? I know if i do go i will have to have it out , i hate having injections in my mouth, god i'm a wimp.
