Psoriasis can affect any part of the body, including the mouth and tongue.
Psoriasis is a chronic autoimmune condition. It causes a person’s skin to grow faster than average, resulting in red and often scaly patches of skin.
These patches can form anywhere on the body. According to the National Psoriasis Foundation, the most common areas are the scalp, elbows, and knees.
Less frequently, psoriasis affects the mouth. Oral psoriasis can cause red patches with yellow or white edges to form on the tongue.

Symptoms of psoriasis on the tongue
Psoriasis can cause noticeable changes in the color, texture, and feeling of the tongue.
For example, people with psoriasis are more likely to develop an inflammatory condition called geographic tongue, or erythema migrans.
The condition stems from an issue with the immune system. It causes the tongue’s skin cells to grow and shed at an irregular rate, resulting in smooth patches.
An estimated 10 percent of people with psoriasis experience geographic tongue, compared to 1–2 percent of the general population.
Symptoms of psoriasis on the tongue include:
- red patches with yellow or white borders
- swelling and redness on the tongue
- smooth patches
- fissures or cracks in the surface of the tongue
Psoriasis on the tongue can be tricky to diagnose because signs may be mild or even unnoticeable.
However, for some people, these symptoms can lead to pain or swelling so severe that it makes eating or drinking difficult.
