6 Things I Learned About Canker Sores


According to Business Insider, canker sores are “the most common type of mouth ulcer.” They are open and painful mouth ulcers or sores that occur in the lining of the mouth. In some cases, a sore can form in the lip, on the jawbone or underneath your bottom lip. Some doctors might use a numbing agent or local anesthetic to relieve the pain while they treat this type of sore.

What are Canker Sores?

Canker sores are small, painful blisters on the inside of the mouth. They usually develop in people over 50 years old and are caused by infection of the salivary glands.

Canker sores can be very difficult to treat and can often require antibiotics or other medications to help them heal. Sometimes they may also require oral surgery to remove the blister.

Causes of Canker Sores

There are many causes of canker sores, but the most common is bacteria entering the mouth through the nose or mouth. Other causes include flu viruses, sun exposure, acidic foods, and eating certain types of onions.

Canker sores usually cause pain and swelling around the mouth. They may also form blisters. If left untreated, canker sores can become infected and even dangerous. You should see a doctor as soon as possible if you have a canker sore. He or she will likely prescribe an antibiotic to treat it and possibly provide other relief.


People can get canker sores in several different ways.

One of the most common ways people get canker sores is by eating food that has been contaminated with the bacteria helicobacter pylori. Helicobacter pylori is a type of bacteria that inhabits the human stomach, and can cause canker sores if it gets into the mouth.

People also get canker sores by touching their face or eyes without washing their hands first. Canker sores are most commonly caused by the human herpes virus. The virus causes the cells that line the inside of the mouth to break down, and the infection often spreads from the mouth to other parts of the body.

Finally, people can get canker sores by exposure to certain chemicals or ultraviolet light. Chemicals that have this effect include chlorine bleach and pickling acids. UV light from the sun or tanning beds also can cause canker sores.

How to Care for a Canker Sore

Canker sores are a type of minor burn that can occur on the lower lip or cheek. They can be caused by the healing process after an injury, such as a sprained ankle.

To prevent and treat canker sores, it is important to follow these steps:

-Apply cool compresses to the sore area several times a day.
-Eat foods that moderate the inflammation, such as lean protein, moist fruits and vegetables, and milk products. These will help to reduce pain and swelling.
-Avoid fatty foods, caffeine, alcohol, NSAIDs (non-steroidal anti-inflammatory drugs), and spicy food. These can increase inflammation and make the sore worse.
-Reduce stress levels by doing things that you enjoy, such as reading, taking walks, or watching TV.
