Aphthous ulcer is a condition characterized by superficial or deep ulcers of different sizes and colors inside the mouth, on the lips, or under the tongue. There are different causes of aphthous ulcer. This is a non-contagious condition that should not be confused with ulcers around the lips caused by cold or herpes. Here I explain different types of aphthous ulcer as well as its most important causes.

Types of aphthous ulcer

Aphthous ulcers can be classified into three different types: minor, major, and herpetiform.

  • Minor aphthae: Minor aphthae are a common form of aphthous ulcer generally located on the labial or buccal mucosa, the soft palate, and the floor of the mouth. They can be singular or multiple and tend to be small (less than 1 cm in diameter) and shallow. That is why they are called “minor”. Minor aphthae usually take about 10-214 days to improve. Unfortunately, aphthous ulcer may cause several minor aphthae inside the mouth and pose many problems for the patient. Minor aphthae mainly affect the lips, tongue, and gums.
  • Major aphthae: Major aphthae are larger and involve deeper ulceration and usually take longer to heal. If you have major aphthae, you need to visit an oral medicine doctor to improve them. Major aphthae usually affect tonsils and cause severe pain, especially when eating.
  • Herpetiform: Herpetiform aphthae are more numerous and vesicular in morphology. This type of aphthous ulcers usually occurs in adults and is less likely to scar with healing.

Oral diseases may sometimes have similar symptoms. For example, some people may confuse leukoplakia with aphthous ulcer. Be sure to visit a specialist for the differential diagnosis of oral diseases.

The latter is more common among children but its cause is still unknown. It is noteworthy that the above-mentioned symptoms may vary from person to person. The immune system of humans usually fails to resist one of these conditions, providing conditions for the appearance of aphthous ulcers. The prevalence of aphthous stomatitis is higher in women than men, and it usually occurs during infancy and old age when the immune system is weaker. It usually takes about two weeks for aphthous ulcer to heal. However, you can shorten this period by taking special measures such as regular mouth rinsing.
