This can often be quite painful, and even restrict the mouth from opening.
Wisdom teeth are coming through at the back of the mouth.
Wisdom teeth often come through on an angle. This can result in them becoming ‘impacted’ or stuck up against the tooth in front.
Impacted wisdom teeth often create a gap between the tooth in front where food gets caught which can create a hole on both the wisdom tooth and the tooth in front of it.
Impacted teeth also often cannot come through fully, and have a little flap of gum at the back which is another place for bacteria and debris to hide.
This often results in quite pronounced pain and swelling.
The swelling and pain can keep returning and become more and more severe each time. If the swelling becomes very severe, it can restrict the mouth from opening, and even block the throat and the airway.
Decay can develop in both the wisdom tooth and the tooth in front, which may result in the need for both teeth to be removed.
