Mouth ulcers are small, painful sores inside the mouth that most people get from time to time. They are usually harmless and heal on their own, but some need attention.
Most mouth ulcers are harmless and heal within one to two weeks. Common triggers include accidental bites, stress, acidic or spicy foods, and a sharp tooth or appliance. Relief comes from avoiding triggers, using a soothing gel and salt-water rinses. See a dentist if an ulcer lasts more than three weeks, keeps returning, or is unusually large, as persistent ulcers need checking.
Common causes
- Accidentally biting the cheek or tongue.
- Stress, tiredness, or hormonal changes.
- Acidic or spicy foods, or a reaction to certain toothpastes.
- A sharp tooth, filling or appliance rubbing the area.
- Sometimes vitamin or iron deficiency.
How to ease them
- Rinse with warm salt water a few times a day.
- Use an over-the-counter ulcer gel for pain.
- Avoid spicy, acidic, and very hot foods while it heals.
- Keep the mouth clean with gentle brushing.
When to see a dentist
Get any ulcer checked if it lasts longer than three weeks, recurs often, is unusually large or painful, or is linked to a sharp tooth. Persistent ulcers should always be examined to rule out other causes.
Book a check at The Tooth Studio if an ulcer will not heal.
