Canker Sores: Causes, Types, Treatment, and Prevention Tips

Canker sores are one of the most prevalent forms of mouth ulcers. Medically known as "aphthous ulcer," canker sores are tiny, superficial wounds that grow on the soft tissues in your mouth or at the bottom of your gums. They are common in younger adults and women but can happen at any age. Most canker sores get cured on their own within a week or two. However, you should consult your doctor or dentist if your canker sores are abnormally large or painful or they don't seem to heal.

2.Complex Canker Sores

They are less common, bigger, and more painful. They may persist up to a month and leave a scar. Complex canker sores are generally due to an underlying ailment.
