My husband's "fang" tooth cracked last night and fell out. All that is left is part of his tooth left in the gum,he went to the dentist today and they said they could give the little bit of tooth he has left a root canal and pull back the gum and I guess build on that and make a crown. Well it is going to be $2000.00 with dental insurance.so he is going to ask about a partial,bridge or implant. What way should he go?
