Tooth Ulcer on Roof of Mouth

Tooth Ulcer on Roof of Mouth

Most of the time, a tooth ulcer on the roof of the mouth is actually a mouth ulcer or another irritated spot, rather than an ulcer caused by the tooth itself. These sores often settle down within a week or two, especially when the irritation stops.

Why Did It Show Up There?

The roof of your mouth takes a surprising amount of abuse. A sharp piece of food can scrape it. A dental procedure can leave the tissue irritated. And biting into food that’s too hot can cause a painful burn that looks a lot like a sore while it heals.

Canker sores can also appear on the soft palate. They often have a pale center with a red edge and can hurt quite a bit, particularly when food rubs against them. The annoying part is that there isn’t always one obvious reason they appeared. Stress, minor injury and certain food triggers are all linked with them.

Could a Tooth Be Causing It?

Sometimes, yes. A rough or broken tooth can repeatedly rub against nearby tissue. A dental appliance can do something similar. If the sore keeps appearing in exactly the same place, it’s worth having a dentist look at the area rather than simply waiting for it to disappear.

What You Can Do at Home

• Skip very spicy or acidic foods for now. They tend to sting the sore and make eating feel much harder than it needs to.

• Warm salt water is a simple option, and honestly, it feels better than repeatedly poking the sore to see if it’s still there.

• If the pain is getting in the way of eating, an oral pain-relief product may make things more comfortable, but follow the label and ask a pharmacist or dentist if you’re unsure what suits you.

When Should You See a Dentist?

See a dentist or doctor if the ulcer lasts two weeks or more, keeps returning, becomes unusually large or makes eating and drinking very difficult. Persistent mouth sores sometimes need a closer examination because they can be linked with an underlying condition.

Also pay attention if the area doesn’t really look like an ulcer. A lump, a hard bump or a patch that doesn’t heal is a different situation and shouldn’t be diagnosed from a quick glance in the bathroom mirror.

One More Thing About the Roof of Your Mouth

If the sore appeared right after eating something extremely hot, a burn may be the simpler explanation. The palate has sensitive tissue, so even a small burn can hurt a lot before it settles.
