Oral ulcers, also known as mouth sores, are small, painful lesions that can develop on the soft tissues inside the mouth, including the tongue, inner cheeks, gums, or the roof of the mouth. These ulcers can cause significant discomfort and interfere with daily activities such as eating, drinking, and speaking. While most oral ulcers heal on their own, understanding their causes, treatment options, and preventive measures can help manage and accelerate healing effectively.
