In brief: Canker sore
Canker sores are white ulcerations, or crater,with a red border usually on the floor of your mouth, or the area where your cheek meets the gum tissues.
They last about a week and will heal naturally.

They can also occur along the side of the tongue and be very painful for a day or 2.

In brief: Canker Sores
Generally, canker sores are painful and have a white crater in the center surrounded by a rim of bright red inflammation.
They usually go away after a few days, but there are ways to treat them with topical cortisone or an injection or cortisone that will make them resolve much faster. See you dermatologist for help.
