Wisdom teeth are also called third molars. They are the last permanent teeth that you will get. They usually erupt during your late teens or early 20s.
When wisdom teeth come in right, they will not cause problems. Sometimes there isn’t room in your mouth for these teeth. That’s when they keep growing in your gum tissue.
When this happens these teeth can harm your other teeth or cause infection. If wisdom teeth are partly erupted, they can be hard to clean and become an easy target for bacteria and cavities.
It’s important to see your dentist twice a year to let him/her check your wisdom teeth. They may need to be removed so you can keep a healthy mouth.
