What's the Difference Between Canker Sores and Cold Sores?

Posted on 3/11/2015 by Robert Leale
Mouth irritation can happen when you have a canker sore or cold sore. Despite how well you take care of your oral health, there are times when you may experience mouth irritation or sores. Some are harmless and will leave all on their own; others could be serious and should never be ignored. Canker sores and cold sores are two of the most common mouth irritations that you can experience.

Canker Sores

Canker sores are mouth irritations that are not contagious. They appear small and grayish with a red border. These are the sores that will appear on the inside of the mouth. There are many issues that can cause canker sores such as allergies, fatigue, and stress, though many dentists believe that they will start when a virus or bacteria starts to attach to the immune system. Most canker sores heal within two weeks on their own with no action required from you.

Cold Sores

Cold sores are a mouth irritation that might require a little more attention than canker sores. These are often called fever blisters and they are often contagious. They are blisters that are full of fluid that will erupt by the lips and under the nose, or on the chin in some cases. Cold sores are the result of a virus called herpes simplex, and once you are infected this virus is remains in the blood stream. This means that the cold sore can come back over and over again after you have been infected just once.

Proper oral hygiene is the best way to ensure that these mouth irritations do not occur and that they heal as quickly as possible. If you experience any type of mouth sores that are a cause for concern, please contact us right away so that we may help you get comfortable as well as eliminate the problem.
