Trench mouth is a painful form of gingivitis (gum inflammation). The term "trench mouth" comes from World War I, when the disorder was common among soldiers. The mouth normally contains a balance of different microorganisms. Trench mouth occurs when there is an overabundance of normal mouth bacteria resulting in infection of the gums, which develop painful ulcers. Viruses may be involved in allowing the bacteria to overgrow. Risks include the following: - Poor oral hygiene
- Poor nutrition
- Throat, tooth or mouth infections
- Smoking
- Emotional stress
This disorder is rare. When it does occur, trench mouth most often affects adults younger than 35.
