Be sure of diagnosis: Get examined especially if that bothersome. Canker sores are common aphthous ulcers of mouth that occur situationally often in response to stressors, are bacterial or viral, & can be treated topically with many OTC products that reduce local discomfort &potentially speed healing. However, oral/dental problems & a number of systemic diseases cause canker sore-like lesions--Crohn's, Behcet's, STD's.
