Aphthous ulcer

Aphthous ulcers, also known as a canker sore, are the most common type of mouth ulcers. A report said that one in five individuals might develop aphthous ulcers in any stage of their life. These ulcers in mouth are painful and recur from time to time.

Aphthous ulcers are the painful sores that affect the lining tissues of the oral cavity. These painful sores occur anywhere in the mouth except the hard palate (roof of the mouth) or on the gums present right beside the teeth. The ulcers appear as small, shallow lesions. These lesions cause difficulty to eat. This type of ulcer is most commonly seen in the age group of 10 to 20 years.

The symptoms of aphthous ulcer include:

  • Formation of a small, oval-shaped, white or yellow colored ulcer
  • Painful red area surrounding the ulcer
  • Tingling sensation in the mouth

Swollen lymph nodes, fever, and weakness found in some cases. Also, the canker sores or aphthous ulcer heals without scarring in one or two weeks.Then your doctor may suggest you certain laboratory tests to rule out other health conditions such as cancer.
