Wisdom teeth usually emerge from the gum between the ages of 17 and 24. They are the last of the large grinding teeth at the back of the mouth (molars). Some people never develop wisdom teeth but you could have up to four – one in each corner of your mouth.
Wisdom teeth don’t usually cause any problems and so don’t need to be removed. However, if there isn’t enough space for them to grow at the back of your mouth (impacted wisdom teeth), they can cause pain, swelling or infection.
Having your impacted wisdom teeth surgically removed (extracted) can help relieve your symptoms.
