What a Sore on Your Mouth Might Mean
It can be alarming to find a sore in or around your mouth. Is it a canker sore or a cold sore? Knowing the difference is the first step to getting relief. It’s a common point of confusion, but they have clear differences. We’ll help you understand what to look for.
Common Causes of Canker Sores and Cold Sores
Canker sores show up inside your mouth. They are not contagious. Their exact cause is unknown, but some things can trigger them. These include minor injuries from dental work, accidental cheek bites, or even stress. Certain foods can also be a factor for some people.
Cold sores, also known as fever blisters, are different. They are caused by the herpes simplex virus (HSV-1). This virus is very common and contagious. Once you have the virus, it stays in your body. It can be triggered by things like stress, a cold or fever, or sun exposure. Cold sores usually appear on or around the lips.
What to Do Now
Figuring out which sore you have can help you find the right treatment. Here’s a simple plan to follow:
- Check the location. If the sore is inside your mouth, it’s likely a canker sore. If it’s on your lips or the outside of your mouth, it’s probably a cold sore.
- Think about how it started. Did you bite your cheek or feel stressed? That might point to a canker sore. Do you feel a tingling or itching before the blister appears? That’s a classic sign of a cold sore.
- Get a clear picture of your oral health. For canker sores, over-the-counter remedies can help with pain. For cold sores, antiviral creams can speed up healing. If you're not sure, or if sores are a regular problem, the DentaSmart app can help you track your symptoms and get expert advice.
