What is a common cause of epulis?

The correct answer is that wearing ill-fitting complete or partial dentures is a common cause of epulis. Epulis refers to a benign tumor or growth that occurs on the gums, often presenting as an enlargement or swelling in that area.

Ill-fitting dentures can irritate the underlying gum tissue due to constant friction and pressure. This irritation can lead to localized inflammation and, eventually, the formation of epulis as the tissue reacts to the ongoing trauma. It is essential for individuals with dentures to have them properly fitted and adjusted by a dental professional to prevent such complications.

While staining from tobacco use, gum disease, and allergic reactions can affect oral health, they are not direct causes of epulis. Tobacco staining primarily affects the appearance of teeth and soft tissues without necessarily leading to growths like epulis. Gum disease, while it can cause changes in the gums, typically does not manifest as epulis itself. Allergic reactions may lead to swelling or irritation but are less commonly associated with the formation of these localized tumors on the gums compared to the mechanical irritation caused by dentures.
