What is a Canker Sore?
Canker sores are also known as aphthous ulcers. They are tiny and painful lesions that develop at the base of the gums or inside the mouth. Canker sores are commonly gray, white, or yellow in color, surrounded with a red border and it may also appear on the lips, the lining of the cheeks inside the mouth, tongue, and throat.
Although canker sores are the most common type of lesions in the mouth, women often get more of these than men. There are three types of canker sores:
- Minor canker sores that rarely appears in a year and may last only up to 10 to 14 days with no scars.
- Major canker sores that has a diameter larger than 10 mm. Unlike minor canker sores, healing may take up to weeks to months and also leave a scar.
- Herpetiform sores are big groups of other sores present at the same time as many as 100. These are small ulcers that tend to heal with no scars at all.

Canker Sore Vs Cold Sore
Many are confused by these two ailments since both cold sores and canker sores are small and share the same triggers and symptoms and sometimes, both occur on the same spot but it’s very important to know the distinction of both for the best proper treatment. A cold sore is contagious, unlike the canker sores. Canker sores appear inside the mouth while cold sores usually appear outside at the side of the lips or mouth. Cold sores are commonly related with the herpes simplex virus.
