You’ve probably heard about cold sores and canker sores, but what do you know about the two? While the two may seem very similar, there are a number of differences between the two. Similarly, do you ever wonder what you can do to avoid canker sores and cold sores—or what you can do to address either type of sore?

In reality, the main difference between the two is their location. Canker sores are always found inside the mouth, though they can be virtually anywhere inside your mouth. Also, canker sores are usually gray, yellow, or white with a red ring around it. These are open sores, but they aren’t contagious. Still, they can be very unpleasant. Unfortunately, no one knows the exact cause of canker sores, but some claim that they are affected by stress, vitamin or mineral deficiencies, food allergies, and even hormones.

Conversely, cold sores are red blisters that form outside of your mouth. Cold sores, which are also known as fever blisters, can actually cause a fever, swollen lymph nodes, and even headaches. Like canker sores, cold sores don’t last very long. However, unlike canker sores, cold sores are very contagious.

Do you have a sore that you’re worried about? Do you have more questions about the differences between canker sores and cold sores? Please remember that if you have a sore that lasts for more than three weeks, we recommend contacting our dentists as soon as possible. Dr. Blass, Dr. Richtsmeier, Dr. Richtsmeier, and our team will be happy to assess the health of your mouth and help you address any of your needs.
