The hole left behind by a tooth doesn’t stay empty for long. A gauze will be used to stop any bleeding and allow a clot to form. In some cases, stitches may be needed to close the socket. The gums will swell temporarily. Over time, the area will be filled in by gums or teeth which will naturally shift. The space may eventually be filled with replacement teeth such as dentures or crowns. Braces can move other teeth to fill the sockets. Wisdom teeth, being in the very back of the mouth, won’t require replacements.
