How Long Do Mouth Ulcers Last?

2 min read

Mouth ulcers always seem to show up at the worst time. Right before a holiday. Just before an important meeting. Or the day you suddenly decide spicy food sounds like a great idea. Then every bite reminds you they’re there.

Most Mouth Ulcers Heal Faster Than You Think

The good news is that most mouth ulcers last around 7 to 14 days. They usually begin with a sore spot that turns into a small round ulcer. For a few days it feels surprisingly painful, then the discomfort slowly fades. The sore gets smaller and eventually disappears without leaving a scar.

Smaller ulcers often feel worse than they look. That’s the frustrating part. By the end of the first week you’ll probably notice eating feels easier, even if the spot hasn’t completely gone yet.

Why Some Ulcers Hang Around Longer

Not every ulcer follows the same schedule. A larger one can stick around for several weeks. If the sore keeps growing, becomes unusually painful, or refuses to heal after about two weeks, don’t ignore it. That deserves a proper dental or medical check.

And if ulcers keep coming back every month, there’s usually a reason hiding underneath. Sometimes it’s a vitamin deficiency. Sometimes your mouth keeps getting irritated by a sharp tooth or braces. Stress has a habit of making things worse too. I’m convinced stress gets blamed for a lot because it deserves the blame more often than people think.

A Few Things That Help Them Heal

You can’t force an ulcer to disappear overnight. Anyone promising that is overselling it. What you can do is stop making it angrier so your mouth gets a chance to heal.

• Warm salt water. It sounds almost too simple, though plenty of people swear by it because it keeps the area feeling cleaner.

• Skip food that burns the sore. Even your favorite curry can wait a couple of days.

• A soft toothbrush helps if brushing has started to feel like punishment.

• Pain relief gels from the pharmacy often make eating much easier, especially during the first few days.

When It’s Time to Get It Checked

Here’s the thing. A mouth ulcer that lasts longer than two weeks isn’t something I’d shrug off. The same goes for ulcers that bleed a lot or make it difficult to swallow.
