Impacted wisdom teeth can be categorised whether they are completely encased in the jawbone. If it is completely encased it is a bony impaction.
If the wisdom tooth has erupted out of the jaw bone but not through the gumline, it’s called a soft tissue.
Sometimes the wisdom tooth fails to erupt completely through the gum bed & the gum at the back of the wisdom tooth extends over the biting surface, forming a soft tissue flap or lid around the tooth called an operculum. |
