Over Eruption Due to Missing Teeth

Dr. Richard Nejat, DDS

When all of the teeth are present in both jaws, there is stability. Teeth are not actually rigid in the mouth, but stay in place due to a complex series of pressure contacts and eruption forces. This series is broken when a tooth or teeth are lost or missing, and one of the possible effects is overeruption of the opposing teeth. Let’s take a look at how this occurs.

All Teeth are present

The presence of all teeth creates stability in the jaw.

Over Eruption

Without the counter forces of the bottom teeth, the top teeth may overerupt.
