Root Amputation

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.

When is root amputation necessary?

It is important to note that root amputation can only be performed on an otherwise healthy tooth. Even in the case of a “key” tooth, extraction will be performed if the tooth is diseased, badly fractured or otherwise injured. Suitable teeth for root amputation have a healthy tooth surface, strong bone support and healthy underlying gums.

There are several problems that may lead to root amputation including:

  • Broken, fractured or injured teeth and roots.
  • Embedded bacteria within the structure of the root.
  • Severe bone loss in a concentrated area due to periodontitis.
  • Tooth decay in a concentrated area of the tooth.

What does root amputation involve?

Prior to root amputation, it is necessary to perform root canal treatment. The amputation itself involves cutting deep into the tooth where blood vessels and nerves are located. For this reason, the pulp of the tooth including these vessels and nerves needs to be removed before resectioning the roots. The root canal and amputation treatments will be performed under local anesthetic.

During the root amputation procedure, a small incision will be created in the gum to fully expose the roots of the affected tooth. The root will be sectioned off from the rest of the tooth and then removed. To kill any remaining bacteria, the whole area will be cleansed with saline solution, and then sutures (stitches) will be applied to seal the incision.

Finally, a temporary crown or filling will be placed to secure the tooth. Depending on the specific situation, painkillers, antibiotics and a medicated anti-microbial mouthwash may be prescribed. In 7-10 days, the stitches will be removed and the gum will have healed. Arrangements can now be made to place the permanent crown or filling.

If you have any questions or concerns about root amputation, please ask your dentist.

Testimonials

Dr. Hekmat's chairside manner is something that should be cloned, and all young dentists and doctors should be able to see the tender insight that this man gives his patients. Dr. Hekmat is one of the nicest, most skillful, most dedicated men I have ever met. I can't believe I was so lucky to have found him in such a huge, busy metropolis as Los Angeles.

John Burbank, CA

Dr. Hekmat has been my trusted family dentist for many years, not only taking care of me--but my wife, sister, mother, brother-in-law and mother-in-law, too! From the warm smiles that greet me when I walk in the door to the compassionate, skillful and concerned care that Dr. Hekmat and his staff provide, my visits to his office are always like visiting a member of the family. ...And I don’t want to forget to mention that I appreciate the fact that in busy Westwood, Dr. Hekmat still provides completely free, validated parking. That’s no small feat in my part of town!

Louis Santa Monica, CA

Dr. Hekmat and his team are true professionals. He is kind and always has time to answer ALL of my questions and concerns. I began visiting him after a a friend referred to me several years ago and I have not visited any other dentists since getting work done with him because he continuously provides me and my family with excellent work. I have had a root canal, crowns, bonding, whitening and removal of amalgam fillings with him and I could not be happier with his work.

He is also totally available for emergencies, something other doctors shirk at. I was on my way to LAX when my front tooth (it was being prepped for a root canal) totally came off, I panicked, called him and drove myself to his office within a hour he had me all patched up.

He never tries to sell you anything, he and his staff know my name and always make me feel welcome and calm the anxiety that comes with getting dental work done.
