Though canker sores are often confused with cold sores or fever blisters that are contagious, canker sores are not able to be spread to someone else. Canker sores are a problem that nearly everyone will deal with at some point in life.
Here’s the difference between these commonly confused medical conditions:
Cold sores and fever blisters are caused by the herpes virus (HSV1) and usually occur on or around the lips, but can also occur inside the mouth on the gums, tongue, and palate especially in acute cases.
Canker sores are small painful red-bordered ulcers with a white or yellowish base. They generally occur inside the mouth on more moveable tissue (under the tongue, cheeks, and inside the lips).
From genetics to serious diseases, canker sores may develop for many reasons. When you know the cause of your canker sore outbreaks, treating these painful mouth sores may become easier. Unexplained canker sore outbreaks may indicate an underlying problem and warrant a trip to see your dentist.
There are treatments and remedies that may help ease the pain from canker sores and possibly help speed up the healing process. It is important to keep in mind that the outcome from any course of treatment, whether it be prescription medication, over-the-counter products, or home-made remedies will be partially influenced by the individual and certainly dependent on the type and severity of the canker sores.
