When removing a tooth it is important to consider what will be done with the empty space after that tooth is removed. Wisdom teeth are in the back of the mouth, so that site will heal and not usually require a restoration. If it is necessary to remove another tooth, replacement options should be discussed. If a tooth is removed and nothing is done with the extraction site, the jaw bone will gradually shrink. Bite forces will cause your teeth to shift. This will eventually reduce the space available for a replacement tooth and change the root angle .

If you want to fill the space with a dental implant, sufficient bone is necessary to place the implant. If you opt for a dental bridge, the bridge must be supported by strong adjacent teeth.

Bone particles can be placed into the hole left by a tooth extraction. As these heal and knit in with the body's existing bone they provide strength and shape to help preserve bone volume.
