An impacted wisdom tooth may keep pushing against the molar next to it. This can cause a resorption cavity where the wisdom tooth hits the other molar.This often leads to serious damage to both teeth.
The molars may become infected or abscessed. Removal of both molars is often needed. Resorption cavities are uncommon.
Increased Risk of Cavities
Wisdom teeth are located right at the back of the mouth and are therefore often neglected in the cleaning process. This means that they are much more likely to get cavities. The location of the tooth means that these cavities are often difficult to treat which can have a flow on effect. The decay from the wisdom tooth can move to the molar next to it.
