Mouth ulcers can be caused by various factors, including minor injury from dental work or biting the cheek, stress, hormonal changes, certain foods, and underlying health conditions.

Over-the-counter topical treatments or mouth rinses containing numbing agents can help relieve the pain associated with mouth ulcers

Some home remedies, such as rinsing with saltwater or applying a baking soda paste to the ulcer, may help reduce pain and promote healing.

If mouth ulcers are severe, persist for more than two weeks, or are accompanied by other symptoms such as fever or difficulty swallowing, it’s important to seek professional evaluation.
