Why a Tooth Can Cause an Ulcer
The tip of your tongue moves constantly. So if a tooth has a rough corner, your tongue keeps finding it, especially while you’re eating or talking, and that repeated rubbing can stop a small injury from healing properly.
Sometimes the trigger is obvious. You bite your tongue while eating and notice the sore later. Other times, the problem is that one tooth has become slightly sharp. You may not notice the tooth at all until the same spot on your tongue starts hurting.
Look for the Irritating Spot
Run your tongue gently around your teeth and pay attention to the area near the ulcer. Don’t keep poking the sore itself. If one tooth feels unusually sharp or rough, that’s worth mentioning to your dentist.
What You Can Do at Home
• Soft foods for a few days, because scraping the sore with crunchy food is just asking for trouble.
• Skip very spicy or acidic foods while the area is tender. They tend to make the sting much worse.
• A soft-bristled toothbrush. Your tongue doesn’t need another fight right now.
• Salt-water rinsing can keep the area comfortable, though it won’t magically make the ulcer disappear overnight.
When You Should See a Dentist
A normal mouth ulcer should gradually improve. If the sore keeps returning in exactly the same place, especially beside a sharp tooth or filling, get it checked rather than treating the ulcer over and over.
And don’t ignore a sore that lasts longer than three weeks. An ulcer that stays around, becomes more painful, bleeds, or looks different from your usual ulcers deserves an examination by a dentist or doctor. Persistent mouth ulcers can occasionally be linked to more serious problems, so this is one situation where waiting it out isn’t clever.
The Tooth May Be the Real Problem
If the ulcer is sitting against a sharp tooth, the best solution may be surprisingly simple. Your dentist can check the tooth and see whether a rough filling, chipped edge, or another dental issue is repeatedly irritating your tongue.
