What are aphthae?
Aphthae are round or oval small wounds that appear in your mouth. They are also called sores or ulcers.
Usually they are 2 to 8 mm in diameter. It is amazing that they are so small, because when you rub them with your tongue or your teeth, it feels as if you had a golf-ball in your mouth.
Aphthae appear on your inner cheeks, your tongue, your palate, or on your lower gums. They are yellow or white, surrounded by a redder area.
Usually, only one appears, but, occasionally, you could have more than 20 at a time!
Although they are annoying, we do not need to worry when we have them. Most of them heal by themselves, without leaving any scars.
