Wisdom teeth are no different than other teeth except that they are the last to erupt, or grow, into the mouth. Wisdom teeth, also known as third molars, are just as useful as any other tooth if they grow in properly and have healthy gum tissue around them. Often, however, problems develop when the teeth grow in, and removal may be required.
Wisdom teeth may be impacted, or unable to erupt, and can cause problems such as infection or cyst formation.
Wisdom teeth may only partially erupt. When this happens, food gets caught in the gums and may cause an infection, swelling, growth of a tumor or cyst and pain.
There is a chance that poorly aligned wisdom teeth will damage adjacent teeth.
A cyst (fluid-filled sac) may form near the wisdom teeth, destroying surrounding structures such as bone or tooth roots.
If wisdom teeth have erupted, the key to preserving them is maintaining good oral health by brushing twice a day and going to see a dentist regularly.
Did you know?
Wisdom teeth usually grow in at around age 18 to 20 years. Since that is considered to be the age when people become wiser, third molars gained the nickname, "wisdom teeth."
What is an impaction?
When wisdom teeth cannot erupt properly, they are referred to as “impacted.” Teeth that have not erupted are not necessarily impacted. It may be that it is still too early in a person’s dental development, and as time passes, the teeth may grow in properly. A dentist must examine a patient’s mouth and x-rays to determine whether the teeth are impacted or will grow in properly. Impacted teeth can result in infection, decay of adjacent teeth, gum disease or formation of a cyst or tumor. Many dentists recommend removal of impacted wisdom teeth to prevent potential problems.
