You should go to a dentist and get it checked out. Depending on how bad the break is, it can be result in different types of treatment. If its small, a filling/bonding can be done to it (white filling) to replace whats missing. If its more severe, a root canal may be needed and then a crown placed possibly. If its very severe, the tooth may need to come out.
Well, if its broken down to the gumline, there's not alot of tooth structure left. I would guess that it would probably need to be removed then and replaced with a bridge or dental implant.
Well it seems really severe to me. There is an extremely small amount of enamel left and I cant see how they would manage to pull it out. I am going to take your advice and just visit a dentist. Thanks for your help.
