Is It Possible to Remove a Cavity on a Wisdom Tooth?

Wisdom teeth, much like other teeth, can develop cavities that need treatment. Whether you can have a cavity filled or if the tooth needs to be extracted is often determined by the accessibility of the cavity and the specific circumstances surrounding the tooth's position.

Accessing the Cavity

A wisdom tooth can be filled or undergo a root canal treatment just like any other tooth. However, if there is an operculum—a flap of gums covering the wisdom tooth—it can complicate the process. Before a filling can be placed, the operculum might need to be removed to allow better access to the affected area.

The Importance of Regular Dental Check-ups

Regular dental visits are crucial to maintaining oral health. You should visit your general dentist every three months for professional cleanings, minor repairs, and to discuss proper brushing and flossing techniques. These regular visits can help prevent the development of cavities and catch issues early on, making treatment more straightforward and less invasive.

During these visits, your dentist will use dental drills to remove decay and then apply a filling to restore the affected tooth. However, access to the wisdom tooth can be difficult or nonexistent, which significantly impacts the treatment decisions about these teeth. In cases where the tooth is impacted, extraction is often recommended.

Why fill a wisdom tooth when it's so challenging to access? Despite the difficulties, certain conditions allow for filling a wisdom tooth. These include:

The tooth has enough room to erupt successfully. The patient maintains good oral hygiene. The patient has a naturally low decay rate.

It's important to note, however, that wisdom teeth are not always filled. The decision is based on the overall health of the tooth and the patient, as well as the tooth's position and its ability to erupt properly.
