How to diagnose angular cheilitis
It would help if you visited your dermatologist or doctor to diagnose the condition. Your dermatologist will observe your mouth and other areas for skin orientation. Sometimes, your doctor will have to ask you about your lifestyle and the drugs you’ve used in the past. You may also have to share certain information on your family and personal health history.
Knowing that angular cheilitis can be caused by bacteria and fungi infection is essential. So, your dermatologist may have to collect culture swabs from your mouth to send to a lab. Your dermatologist will only take culture swabs if typical treatments have been ineffective.
