Mouth Ulcers : Causes & Diagnosis
Mouth ulcers are caused by many disorders which include:
- Canker sores
- Gingivostomatitis
- Herpes simplex
- Leukoplakia

- Oral thrush
The skin lesion of histoplasmosis may also appear as a mouth ulcer.
Canker sores are more common in young adults than in children or older adults.
Tests & Diagnostics
A health care provider or dentist usually diagnoses the type of mouth ulcer, based on its appearance and location. Blood tests or a biopsy of the ulcer may be needed to confirm the cause.
