Sores In The Mouth

Posted on Nov 03, 2016 by William J. Claiborne, DDS MS

Tis the season! Not only is it cold season, it’s a stressful time of year. This means your likelihood of getting a cold or canker sore increases.

They are often confused, however. The difference is…

Canker Sores
Small ulcers with a white or gray base and a red border. Unlike cold sores, canker sores appear inside the mouth. They are not contagious but their exact cause is uncertain. Some experts believe that immune system problems, bacteria or viruses may be involved.
Fatigue, stress or allergies can increase the likelihood of a canker sore. A cut caused by biting the cheek or tongue, or reactions from hot foods or beverages may contribute to canker sore development. Intestinal problems, such as ulcerative colitis and Crohn’s disease, also seem to make some people more susceptible.
Canker sores usually heal on their own after a week or so. Over-the-counter topical anesthetics, steroid preparations,  and antimicrobial mouth rinses can provide temporary relief.

Cold Sores
Also called fever blisters or Herpes simplex, these are groups of fluid-filled blisters that often erupt around the lips, under the nose, or around the chin. Cold sores caused by herpes virus type 1 are very contagious.
Herpes lesions look like multiple tiny fluid-filled blisters that are most common around the edge of the lips. An outbreak may follow a fever, sunburn, skin abrasions or emotional upset.
Cold sore blisters usually heal in a week by themselves. Over-the-counter topical anesthetics can provide some relief. Prescription antiviral drugs may reduce the duration of these kinds of viral infections.

However, any change to oral tissue that does not heal within 14 days should be examined without delay! This is a symptom of oral cancer. Nearly 40,000 Americans are diagnosed with oral or oropharyngeal (throat) cancer each year. These cancers kill about 1 person every hour, every day.

The survival rate is one of the worst of all cancers. Of those who acquire oral cancer, only 57% are estimated to be living 5 years from now. The death rate is higher than cervical cancer, Hodgkin’s lymphoma, laryngeal cancer, cancer of the testes, thyroid cancer, or skin cancer (malignant melanoma).

The death rate for these cancers has seen a slight decrease since 1980. Unfortunately, some symptoms do not emerge until the cancer has reached an advanced stage because symptoms can mimic a bite on the inside of your cheek.

Because tissue changes in your mouth are normal, ignoring symptoms can prove deadly. The most common are:

• white or red patch of tissue
• lesion in the mouth
• difficulty or discomfort when swallowing
• persistent sore throat
• a lump or mass inside the mouth or neck
• wart-like mass
• numbness in the oral/facial region

Although new cases have been dropping over the past few decades, a recent rise has been seen in throat cancers related to HPV (human papilloma virus) in white males under age 50. The average age of most people diagnosed with these cancers is 62, but about a third occur in patients younger than 55.

Lesions or discolorations that are early warning signs are not always visible, particularly in the back portion of the mouth (the oropharynx, the tonsils, and base of tongue), which can be an obstacle to early diagnosis and treatment. This is yet another reason that keeping your regular oral hygiene exam and cleanings is so important. During these times, your dentist and hygienist look for unusual changes in the mouth that can indicate a problem. However, you should never wait until your scheduled appointment to have anything unusual examined.

Although a stubborn canker or cold sore may not be welcome, they tend to go away in a week or ten days. Again, if an unusual spot or sore is still present after two weeks, call 828-274-9440 immediately for an appointment.
