Much like impacted teeth, which become lodged in gum or bone, retained roots can give rise to infection. This is especially true if the roots are only partially covered. Because the roots are essentially dead material, they can become food for bacteria.

Is it OK to leave roots of teeth?

If the tooth is decayed or has a nerve present which has died, the roots will not be healthy and cannot be left behind.

Is it OK to leave a root tip?

When can root tips be left in place? Root tips can be left in place if the risks of surgery to remove the root tip outweigh the benefits of removing the root tip. To leave a fractured root tip in place, the root tip must be small, deep within the alveolus and must not be infected or have periapical lysis.

Can you pull a tooth and leave the root?

The typical surgical option is a full extraction of the tooth (or teeth), but may also be a coronectomy in which the crown of the tooth is removed but the roots are left in place. A coronectomy is often recommended when the tooth’s roots are close to important nerves, to avoid nerve damage.
