Signs in the mouth you shouldn't ignore
In short: most mouth complaints are mild and passing. But there are a few signs worth not letting slide, and a very simple rule that applies to almost all of them: if something doesn’t heal in 2-3 weeks, have a professional look. It’s not to panic; it’s to not ignore what does need checking.
The 2-3 week rule
A sore, mark, lump or hardened area in the mouth or lip that doesn’t heal on its own in 2-3 weeks deserves a check. Normal ulcers go in a few days; what persists without explanation is what’s worth checking. It’s almost always nothing, but that rule stops you letting the important thing slide.
Gums: when to go from watching to acting
Bleeding a little when brushing is usually mild gingivitis. It’s worth checking if:
- They bleed all the time, not just now and then.
- The gums recede and you see more tooth than normal.
- The teeth start to move or you notice they’re “drifting apart”.
Other signs not to ignore
- Persistent pain in a tooth or area that won’t go.
- White or red patches in the mouth that don’t rub off.
- A lump or thickening that wasn’t there before.
- Persistent bad breath or bad taste with no clear cause.
- Difficulty or pain swallowing or moving the tongue that lasts.
What matters: check-ups and self-checks
Most of these things are caught at a regular check-up before you notice anything. And now and then, look at your mouth in the mirror: lips, gums, tongue, inside the cheeks. Knowing your mouth helps you notice any change in time.

Frequently asked questions
What's the 2-3 week rule?
Any sore, mark, lump or hardened area in the mouth or lip that doesn't heal on its own in 2-3 weeks is worth having a dentist or your doctor look at. The vast majority will be nothing, but that simple rule helps you not let slide what does need checking.
Are bleeding gums a warning sign?
Bleeding now and then is usually gingivitis, mild and reversible. What's worth checking is if they bleed all the time, if the gums recede or if the teeth start to move: there may be more advanced gum disease there that needs treating.
Does having one of these signs mean something serious?
Almost never. Most of these signs have mild, common causes. The idea isn't to panic, but not to ignore them: checking them in time is what lets you sort out whatever it is quickly, mild or not.
