How is dental root amputation performed?

Roots of teeth are complex things, and when the tooth has enough trouble around one root but other roots are strong and solid, the dentist can isolate that root and reshape the whole tooth from the bone up, taking the diseased root away.  The most important thing about it is to leave you able to keep the remainder of the tooth very clean and healthy. Almost always you will need a new crown for that reshaped tooth; when this very complicated work is done well and you take excellent care of it, an tooth with one less root can often last for many years.
Dental root amputation, also known as dental root resection, is usually done in three stages. A root canal is first, to clean out the root's vessels and nerves. The dental root amputation is performed by cutting into the gums near the affected root, and removing the diseased or damaged root. A bone graft is sometimes placed at this time to support the tooth. The last stage is placing a restoration (crown) on the tooth, to help stabilize it. These procedures require several visits.

Dental root amputation is done on a tooth with more than one root, where the main part of the tooth and at least one of the other roots is in good condition. The procedure removes the problematic root and preserves the rest of the tooth.
