Aphthous ulcers or canker sores, those painful little things in the mouth – what helps best?

Anyone who has ever had a small lesion of this kind in the mouth knows how unpleasant aphthea can be. Eating and drinking is severely limited and dental hygiene tends to be neglected.

Chronic recurring apthe (CRA) is the medical term used,  women generally tend to be affected more often. There are three different types commonly mentioned: minoraphthe, majoraphthe and herpetiform ulcers. This distinction is made based on appearance and location!

minorMinoraphthe are the most common: round or oval, flat ulcers of less than 5mm diameter. These usually appear on the flexible part of the gums or mucuous membrane and heal after one or two weeks, without leaving a scar.


majorMajoraphthe are less common, and appear on the gums, lips and palatal arches. They usually take several weeks to heal (up to 6 weeks) and can leave scars.

herpetiformeHerpetiform aphthe are characterized by many hundreds of small lesions, which can appear anywhere in the mouth.


What causes aphthe?
Aphthe is associated with many different kinds of illnesses, e.g.

  • Morbus Behcet
  • Sweet Syndrome
  • familial neutropeny
  • HIV infection

But even healthy persons can develop aphthe, the exact causes are unknown. Various factors such as iron deficiency, vitamin deficiency, glutamate intolerance, food allergies,infections or genetic predisposition have been suggested. Healthy persons often get aphthe after eating nuts, pistachios and/or citrus fruits.

What can I do against aphthe?
As the exact causes are unknown, only the symptoms of aphthe can be treated:

  • Washing out the mouth with astringent solutions such as sage tea
  • local cortico-steroids (Volon A ointment)
  • Softlaser
  • Chlorhexidine mouthwash
  • topical analgesics as lozenges

If aphthe seem to appear after eating certain foods, simply refrain from eating those foods!
