Wisdom teeth are unnecessary third molars located at the very back of your mouth, and usually come in much later than the rest of your teeth.
For many people, when this happens there is not enough space for them to develop properly causing pain and discomfort. If these extra teeth are left in for too long, they can become impacted, or your current teeth can shift attempting to make space causing further complications.
To prevent the pain and discomfort of impacted teeth, a highly skilled dentist will extract them. However, because this is a surgical procedure we recommend having them removed as early as possible so your body has an easier time healing.
