To help it heal quickly, try rinsing your mouth with warm salt water a few times a day. Applying ice wrapped in a clean cloth can also reduce any swelling. Try to avoid spicy, salty, or acidic foods for a few days so you don't irritate it further. This should heal on its own in a week or two, but please reach out to a doctor if it doesn't improve.

Rinse with warm salt water, keep your mouth clean, drink plenty of fluids, and avoid spicy or hot food to reduce irritation. Eat soft foods, maintain hygiene, and try to rest well to support healing. If ulcers are increasing in number, very painful, or a fever persists, consult a doctor to determine the cause and guide proper treatment.

If it does not improve, becomes painful, or keeps coming back, consult a doctor to check the cause and guide proper treatment.
