An unerupted tooth or impacted tooth is a tooth that has developed but not emerged into the mouth like the other teeth. This occasionally happens with wisdom teeth. This procedure is performed to uncover the tooth. During the procedure, the gum on top of the unerupted tooth will be lifted to expose the hidden tooth underneath. Often braces will be placed on the unerupted teeth to create a space for the un-erupted tooth to move. Brackets can then be used to guide the newly exposed tooth into place.
