Canker Sores (Aphthous Ulcers) 🦷
Canker sores are small, painful ulcers that usually develop inside the lips, cheeks, or on the tongue.
They are not contagious and often heal on their own within 1–2 weeks.
Common triggers can include stress, minor trauma, acidic foods, nutritional deficiencies, or irritation.
To help with discomfort:
* Avoid spicy and acidic foods
* Use a gentle salt-water rinse
* Keep the area clean
* Ask your dentist about topical treatments if needed
If a sore lasts more than 2 weeks, keeps coming back, or is unusually large or painful, it should be checked by a dentist or physician.
