Canker sores are not a pleasant thing to experience. Unlike cold sores (which we will talk about in a subsequent blog post) canker sores have no known root cause associated with them. They are known only as ulcers in the mouth that are assumed to be caused by stress or certain acidic foods.

That being said, there are 2 types of canker sores. “Simple canker sores” that pop up a few times a year and can last up to a week, which often occurring in people ages 10-20. And also “complex canker sores”, which are less common but occur more often in those who frequently have canker sores.

The Cause of Canker Sores

Again, canker sores are largely unspecific as to the reasoning behind them. Stress and even tissue injury such as accidently biting your cheek or even brushing too hard on your gums, has been attributed to canker sores, as well as acidic fruit and veggies such as pineapple and tomatoes have been known to trigger canker sores.

An impaired immune system can be a factor too, along with deficiencies in your B12, zinc, folic acid, lack of iron, as well as more severe concerns such as Crohn’s disease.

The Symptoms of Canker Sores

A canker sore feels like an odd and uncomfortable sore inside your mouth, on your tongue, or on the back of your upper mouth. It tingles and has a slight burning sensation before the sore actually appears.

A simple canker store will appear round and white or grey with a red edge, whereas a complex canker sore can involve a fever, the feeling of exhaustion, and even swollen lymph nodes.

How Can You Treat a Canker Sore

Healing will come naturally to a canker sore, but it can take up to a week or more. So in addition to sitting it out naturally, you can flush your mouth with a swish of salt water to help keep it clean, with the hope to also resolve the issue more quickly.

Larger sores can be looked at by a dentist who can prescribe you an antimicrobial mouth rinse, corticosteroid ointment, or they can prescribe a prescription to help with pain and discomfort.
