Root resection surgery

What is the Root resection surgery?

Your molars (back teeth) have three or more roots. Sometimes, the roots of a tooth have good bone support and are free of decay, except for one root. Instead of taking out the whole tooth, your dentist may decide to remove just the one unhealthy root. This is called a root resection.

Occasionally, the dentist also will remove part of the crown (top of the tooth) above that root.

What is the procedure?

Before you can undergo the resectioning procedure, you'll probably have to undergo a root canal treatment first.

This is usually performed under a local anesthetic. The root resectioning procedure usually requires your dentist to make several cuts in your gums so that the roots of your teeth are exposed. Once this is exposed a bur is used to keep the root separate from the other parts of the tooth. Then the dentist will drill to remove the root from the rest of the tooth. Sometimes, part of the crown will be cut. The attached root will be removed along with that section of the crown.

The dentist will rinse the area with a sterile saline solution. A bone graft may be placed in the place where the root was. Then the gum will be stitched closed. You may be given prescriptions for antibiotics and pain medicine.

What kind of result can you expect?

Recovery period and recommendations

You may have some discomfort, swelling and light bleeding for one or two days. Avoid chewing with the tooth until the stitches are removed (7 to 10 days).
