Canker Sores Cause Prevention And TreatmentCommonly occurring during bouts of viral infections, canker sores are among the most common forms of mouth ulcer.

Typically characterised by ovoid inflammatory halos that persist on the surfaces the mouth, canker sores make simple activities like talking and eating uncomfortable.

Basic canker sores are categorised into two different types: simple canker sores and complex canker sores.

Simple canker sores usually appear three to four times every year. Simple canker sores often persist in people between ten and twenty years old. Complex canker sore, on the other hand, is the less common type of canker sore. Complex canker sores are recurring and usually affect people who have previously developed them.

Among possible causes for canker sores include oral trauma that results from ill-fitting dentures, fractured teeth, and cracked fillings, among others. Certain foods are also suspect to the development of canker sores. These mostly consist of acidic fruits and vegetables, including oranges, lemons, pineapples, tomatoes, and strawberries.

People who have been affected with canker sores for more than three weeks are advised to consult with medical or dental professionals.

Prevention And Treatment

To reduce the risk of developing canker sores, you should try to avoid consuming citrus fruits, acidic vegetables, and spicy foods altogether. It also helps to keep your mouth clean and free of canker-sore causing agents using a soft-bristled toothbrush.
