See your dentist : A badly decayed tooth is a serious infection risk. You should see your dentist or oral surgeon to determine if the tooth can be fixed with root canal treatment and a crown. If it is too badly decayed, it will need to be extracted. The tooth can then be later replaced with a dental implant or bridge.

See a dentist: You need to see a dentist. It will probably be extracted if the part above the gum is gone.

Decayed teeth: It depends on how much good tooth is left after removing all the decay. An exam and xray can tell, and see if the tooth can be saved.
