Mouth Ulcers and Patches — When to Get Them Checked — With Lily, Our LS ToothBuddy

Most mouth ulcers heal on their own — but not all. Lily, our LS ToothBuddy, explains the simple 3-week rule for ulcers and patches, and known risk factors like betel quid, tobacco, and alcohol, in under a minute.

Here's What's Going On

Most small mouth ulcers are harmless and heal by themselves within one to two weeks.

But a simple rule matters: if an ulcer, or a red or white patch, doesn't heal within three weeks, get it checked.

Betel quid, tobacco, and alcohol are known risk factors for more serious mouth changes.

A lump, or a patch that won't go away, is worth a proper look, not guessing at home.

Regular dental checkups include a simple mouth screening, quick and painless.
