Small sores called mouth ulcers can develop on your lips, inner cheeks, gums, or palate (roof of mouth). Numerous things, such as minor wounds, hormone fluctuations, and emotional stress, can cause them. Although mouth ulcers aren’t contagious and usually go away on their own, there are treatments available to lessen their painful effects. Aphthous ulcers and canker sores are other names for mouth ulcers.
