Why Stress Can Bring on a Mouth Ulcer
You know those weeks when your brain never seems to switch off? That kind of pressure can show up in your mouth too. Stress and tiredness are recognized triggers for mouth ulcers, although the exact reason some people develop them isn’t completely understood.
The sore itself is usually small and shallow, with a pale center and a red edge. It can sting badly when you eat or brush your teeth. Annoying, especially because something that tiny can suddenly become the only thing you notice.
Stress Isn’t Always the Whole Story
Here’s the thing. Stress might be part of the picture, but don’t automatically blame every mouth ulcer on a rough week. A sharp tooth can rub against the inside of your cheek. Braces or a rough filling can do the same. Some people also get ulcers when their diet is low in certain nutrients.
What You Can Do at Home
• A soft toothbrush is worth using while the area is sore, because scrubbing over an ulcer just makes brushing feel worse.
• Cool drinks can feel much kinder than very hot ones, especially when the ulcer sits somewhere your tongue keeps bumping into.
• Skip foods that sting, particularly anything very spicy or acidic. You don’t get bonus points for eating through the pain.
• A simple salt-water rinse can soothe the area. Mix half a teaspoon of salt into a glass of warm water, rinse, then spit it out.
When a Tooth or Dentist Might Be Involved
Sometimes the stress connection is obvious. Sometimes there’s a rough edge sitting right beside the sore, quietly rubbing it every time you talk. If an ulcer keeps appearing in the same place, have a dentist look for a sharp tooth or dental work that could be irritating the tissue.
When It Needs Checking
• More than three weeks is too long for a typical mouth ulcer, so get it checked by a dentist or doctor.
• If it’s unusually large, keeps coming back, or makes eating and drinking extremely difficult, don’t just keep waiting for it to disappear.
