What will a dentist do to fix a cracked tooth? I noticed a few days ago that I cracked my tooth on a bone. I can see a light line going down the side. So I made a dental appointment. I will be able to see the dentist in three days from now. I am eating really soft foods because I am afraid to brake off my tooth. What will the dentist do to fix it? Will I need to have a crown or can they just use bonding or something like that?
