When you hear the word psoriasis, you automatically associate it with a skin problem. For typical psoriasis, they appear on areas where it is visible such as your scalp, knees, or elbows, but not many expect it to be inside your mouth.
Oral psoriasis is not a life-threatening medical condition.
Symptoms are often mild, and it comes and goes immediately.
The most common areas are in the inside of your cheeks.
