There are few things more irritating than having a painful, swollen sore in your mouth. It bothers you while eating, talking, and even just sitting around. There are a number of types of mouth sores with different causes. Some are infections from bacteria, viruses, or fungus. Or they can be a result of an ill-fitting denture, broken tooth or filling, or loose orthodontic wire. Mouth sores can also be a symptom of a medical condition. Here are some details about common mouth sores.

Canker sore
These small sores occur inside your mouth, and are white or gray with a red outline. They aren’t contagious, but are recurring and can happen one-at-a-time or several at once. Experts believe that lowered immune systems, bacteria, or viruses are risk factors. Canker sores often heal by themselves in about a week, and topical anesthetics or antibacterial mouthwashes may provide relief.

Cold sore
Also called fever blisters, these sores occur outside of your mouth around your lips, nose, or chin. These blisters filled with fluid are caused by the herpes simplex virus type 1, and are extremely contagious. Once you have been infected with the herpes virus, it remains in your body and occasionally flares up. Cold sores usually heal in about a week on their own. Topical anesthetics may help, and your dentist might prescribe antiviral medications to reduce outbreaks.

Candidiasis
Also called oral thrush, candidiasis is a result of the yeast Candida albicans reproducing in large quantities. It usually happens to those with weakened immune systems, and is common with people wearing dentures or with dry mouth syndrome. Candidiasis is also linked to taking antibiotics. Controlling candidiasis is done by preventing or controlling the cause of the outbreak. Ask your dentist for advice.

Leukoplakia
Common with tobacco users, leukoplakia are thick white patches on the inside of your cheeks, gums, or tongue. In addition to tobacco use, they can also be caused by ill-fitting dentures or continual chewing on the inside of your cheek. Leukoplakia is linked with oral cancer, so your dentist may advise a biopsy if the patch looks suspicious.
