Root amputation is a specialized dental procedure, whereby one root is removed from a multi-root tooth. The tooth is then stabilized and rendered fully functional with a crown or filling. The multi-root teeth best suited to the root amputation procedure are the molars at the back of the mouth. These large flat teeth have either two or three roots depending on whether they are situated on the upper or lower jaw.
The general purpose of root amputation is to save an injured or diseased tooth from extraction. Most dentists agree that there is no better alternative than retaining a healthy natural tooth, and the root amputation procedure makes this possible. Dental implants, extensive bridgework and custom-made tooth replacements can be expensive and time-consuming. Generally, root amputation and the necessary crown work are less expensive and can be completed in 1-3 short visits.
