The usual causes of angular cheilitis are typically excessive stress, poor oral hygiene, certain illnesses and types of medications. Any or a combination of all of these can make this problem blow out of proportion to become an infection that may require medical care. It is important that you first get your infection checked out by a medical professional who will accurately be able to gauge the severity of the problem and prescribe any necessary treatment as required. Aside from medical assistance, you can follow some simple measures that will provide relief from the itching and burning sensations that accompany angular cheilitis.
Drinking chilled liquids will numb your mouth and take away the discomfort momentarily. Soft, cold foods that do not irritate any open sores are highly recommended for such lesions. If you wear dentures or braces, you may want to get them refitted, as ill-fitting dentures or braces are a primary cause of these ulcers. You should also take a break from wearing them if they are the cause of the problem. You should rinse your mouth with dilute hydrogen peroxide (one part peroxide, four parts water) for sanitizing. Alternately, you can also use a solution of one tablespoon baking soda in a glass of water for the same purpose. You must avoid sugar, which generally aggravates discomfort.
