This branch of dentistry specializes in saving teeth. If you have a tooth where the pulp has become infected, you have two basic options – either have a root canal or have the tooth pulled. An endodontist will prefer to try and save as much of the tooth as possible by performing a root canal.
Why is saving your natural teeth better than having them yanked out? If you have a tooth pulled, a gap is left in the jawline. An implant can be made to close this gap, but it can also be left as it is. If no implant is added, there is nothing there to keep the surrounding teeth in their correct position.
