Canker sores are the most common type of mouth ulcer that is generally open and painful. They can appear inside the mouth on one’s lips or cheeks. The sore itself is typically white or yellow in the center and is then encompassed by red, inflamed tissue. While it is unknown what exactly causes canker sores, there are a number of suggested causes. The following outlines the top 10 causes of canker sores:

10 CAUSES OF CANKER SORES:

5. Health Issues

Canker sores may be treated by contacting your dentist. Your dentist may be able to prescribe you to certain helpful mouth rinses, antibiotics, or ointments. If you have canker sores that recur or canker sores that won’t heal it is very important to see your dentist and have the lesions assessed immediately; more serious conditions such as oral cancer can resemble canker sores in the very early stages. At Pearl Dental we perform an examination of the soft tissues and cancer screen at every dental exam; this is a good time to discuss any concerns you may have about recurrent canker sores.
