∙ 8y agoAn operculum is a small piece of gum that is covering part of a tooth, usually a wisdom tooth, which has still not erupted fully. If that tooth doesn't erupt further more, the operculum can remain there and be easily infected because food can gather under it and it is very hard to clean.
Sometimes a dentist can do an operculectomy, where he removes that small piece of gum to uncover the tooth, only if that tooth is not impacted.
Another instance of an operculum is a body part on a fish that is the outside structure of the gills.
