What does a mouth ulcer look like?

Answer 1

Normally they are found between your cheeks and gums, under the tongue or on the sides of the tongue. They are either white round patches if on the tongue and small white blisters with pink areas if under the gums.

Canker sores, also known as aphthous ulcers, are small sores that occur inside the mouth. You can get them on the tongue and on the inside of the cheeks and lips - the parts of the mouth that can move. They usually pop up alone, but sometimes they show up in small clusters.

Your mouth might tingle or burn before the actual sore appears. Soon, a small red bump rises. Then after a day or so it bursts, leaving an open, shallow white or yellowish wound with a red border. The sores are often painful and can be up to an inch across, although most of them are much smaller. Occasionally, someone who gets canker sores may also develop a fever and feel sluggish and uncomfortable.
