What Is Canker Sore?

Canker sores are painful red, inflamed lesions that form on the inside of the lips, cheeks, or tongue. They are caused by a variety of factors, including oral bacteria, chemicals, and viruses.

If you experience pain when eating or drinking, talk to your doctor. He or she may be able to diagnose your canker sore and recommend a treatment plan.

Causes of Canker Sore

A canker sore is an infection of the mouth that often occurs after a cold or flu. It is caused by the presence of certain strains of the herpes simplex virus. The virus attacks the cells that line the inside of your mouth and throat. This can make it difficult to eat, drink, and breathe. A canker sore can also lead to permanent damage to your teeth. If you think you may have a canker sore, see your doctor for treatment.

The most common cause of canker sore is Streptococcus mutans, a type of bacterium. Other causes include dental plaque, air pollution, stress, and poor oral hygiene. Treatment depends on the cause of the canker sore, but typically involves antibiotics and pain relief.

How to Cure Canker Sores

If you're like most people, you know something about canker sores, but you're not sure what causes them or how to get rid of them. The first step is to drink plenty of fluids to keep your body hydrated. You should also eat a high-fiber diet to help reduce the inflammation in your mouth. If the sores are severe, you may need antibiotics to clear up the infection. Finally, you should use a topical cream or ointment to soothe and heal the area.

Prevention of Canker Sores

Canker sores are a type of ulcer that can develop on the lips, gums, tongue, or inside of the cheeks. They are caused by bacteria and can be painful and contagious. There are several things you can do to prevent canker sores from developing, including:

  1. Wash your hands often. 

It is important to wash your hands often to prevent canker sores. Hands are one of the most common sources of bacteria. Hand sanitizers are available at most pharmacies and many grocery stores. Washing your hands often will help keep your skin healthy and free from bacteria.

  1. Avoid touching your lips, gum, or tongue.

This includes eating, drinking, and smoking.  If you do accidentally touch your mouth, dampen a tissue and apply it to the area. Repeat this as needed. 

  1. Avoid high-sugar foods and drinks.

These can increase your risk of developing canker sores. These can increase your risk of developing the condition by providing your mouth with excessive amounts of sugar. This can cause your body to produce more acid, which can lead to canker sores. 

  1. Avoid using harsh soaps and toothpaste on your skin.

It is important to avoid using harsh soaps and toothpaste on your skin. These products are very abrasive and can cause damage to the layer of skin that defends against infection. Instead, use a mild soap or mouthwash that does not contain any chemicals. If you do get a canker sore, try to clean it as soon as possible with warm water and mild soap.

  1. Floss using a water flosser.

Canker sores are a common problem that can be prevented with proper dental hygiene. The best way to prevent them is by flossing using a B. Weiss water flosser. It is more effective than using regular floss because it reaches all the tiny gaps between teeth. This method is gentle on your gums and helps remove plaque and food particles that may cause canker sores.

What to do if you get a Canker sore

If you are unfortunate enough to get a canker sore, here is what you need to know:

First and foremost, avoid picking at the sore. This will only make it worse.

Try to drink plenty of fluids to help flush out the infection. If you are able, try sucking on ice chips or popsicles.

Avoid foods that may contain acids or sugars that could irritate the skin.

Apply a pain reliever such as ibuprofen or acetaminophen if the sore is really bothering you.

For minor cases that do not require antibiotics, over-the-counter remedies such as ibuprofen or calamine lotion may work just fine.
