Understanding Mouth Sores: A Guided Look at Aphthous Stomatitis vs. Oral Herpes

Mouth sores can be a common and uncomfortable issue for many individuals. While some assume a herpes infection, it's often a different condition entirely. This article delves into the distinction between aphthous stomatitis (canker sores) and oral herpes, offering insights and practical advice to help you identify and treat these sores effectively.

Identifying the Causes: Aphthous Stomatitis and Oral Herpes

Oral herpes, the most well-known among mouth sores, is caused by the Herpes simplex virus (HSV). However, if you have tested negative for this virus but still experience recurring sores, it is likely that you are dealing with aphthous stomatitis, also known as canker sores.

Aphthous Stomatitis vs. Oral Herpes

Aphthous stomatitis, commonly referred to as canker sores, and oral herpes are two distinct conditions with different symptoms and treatments. Aphthous stomatitis is characterized by painful ulcers that appear on the inside of the mouth, cheeks, and tongue. It is not contagious, which means you can kiss or share food with others without fear of transmitting the sores.

Oral herpes, on the other hand, is caused by the Herpes simplex virus (HSV-1 or HSV-2) and causes cold sores around the mouth and lips. This virus can be contagious, especially when sores are present.

Symptoms and Characteristics

Aphthous Stomatitis

The hallmark of aphthous stomatitis is the appearance of small, shallow ulcers or sores in the mouth. These sores are usually round or oval with a red border and a grayish white center. Unlike oral herpes, aphthous stomatitis does not form blisters around the lips or an ulcerated area on the tongue. These sores can be very painful and can last for a few days to several weeks.

Oral Herpes

Oral herpes, when present, often manifests as painful, fluid-filled blisters around the lips and mouth. When these blisters rupture, they form lesions similar to cottage cheese. These lesions can be contagious and can spread the virus to others. Unlike aphthous stomatitis, it may also involve pain and sensitivity in the affected area, as well as flu-like symptoms.

Diagnosis and Testing

Since aphthous stomatitis and oral herpes can cause similar symptoms, the only way to confirm a diagnosis is through a medical examination. If you suspect you may have both conditions, it is essential to consult a healthcare provider. They can conduct a visual examination and may perform a viral culture or blood test to rule out HSV and identify other possible causes.

Testing Procedures

Testing for both conditions typically involves:

A routine mouth examination by a healthcare provider to check for any characteristic sores. An HSV blood test if there is a suspicion of herpes. A biopsy of the sore if needed to further evaluate its nature.

Effective Treatment: Managing Aphthous Stomatitis

For individuals dealing with aphthous stomatitis, effective management and treatment can significantly alleviate discomfort and speed up the healing process. Here’s a recommended treatment method that has worked for the author:

Salt Water Treatment for Canker Sores

Follow these steps to treat your canker sores:

Fill a glass with approximately half a cup of warm (not hot) water. Pour in a sufficient amount of salt and swirl the water until it fully dissolves. Keep swirling until the salt no longer dissolves, indicating a saturated solution. Use a swig of the saturated salt water and hold it over the sore for at least 30 seconds. Spit the water out and repeat the process 2-3 times. Do not rinse your mouth afterward. Use a small amount of fresh water on your tongue to swallow and remove the salt taste.

Apply this treatment daily in the morning and evening. The sores typically resolve within 2-3 days, depending on the severity of the infection.
