Gingivostomatitis is an infection of the mouth and gums that leads to swelling and sores. It may be due to a virus or bacteria.
Gingivostomatitis is common among children. It may occur after infection with the herpes simplex virus type 1 (HSV-1), which also causes cold sores.
The condition may also occur after infection with a coxsackie virus.
It may occur in people with poor oral hygiene.
The symptoms can be mild or severe and may include:
Your health care provider will check your mouth for small ulcers. These sores are similar to mouth ulcers caused by other conditions. Cough, fever, or muscle aches may indicate other conditions.
Most of the time, no special tests are needed to diagnose gingivostomatitis. However, the provider may take a small piece of tissue from the sore to check for a viral or bacterial infection. This is called a culture. A biopsy may be done to rule out other types of mouth ulcers.
The goal of treatment is to reduce symptoms.
Things you can do at home include:
You may need to take antibiotics.
You may need to have the infected tissue removed by the dentist (called debridement).
Gingivostomatitis infections range from mild to severe and painful. The sores often get better in 2 or 3 weeks with or without treatment. Treatment may reduce discomfort and speed healing.
Gingivostomatitis may disguise other, more serious mouth ulcers.
