What is an impacted third molar?
2 A third molar is considered to be impacted when it fails to erupt or only partially erupts through the gum tissue. Impacted third molars are very common and often cause no pain or problems. It’s important to remember that whether they are erupted or impacted, it is possible for wisdom teeth to cause problems if they are not properly cared for by brushing, flossing, and having regular visits to your dentist.
