Psoriasis is a chronic inflammatory disease that affects 2-3% of the population. It can appear as scaly, red skin plaques on various parts of the body, including the mouth. Oral psoriasis can occur on the tongue and gums, but not on the teeth. Symptoms of oral psoriasis include discomfort and inflammation in the mouth. People with psoriasis often have worse dental health due to gum inflammation, bone loss, and missing teeth. If you have psoriasis and notice mouth pain, see your doctor or dentist. They can help manage your symptoms and identify triggers that worsen your condition. Avoiding certain foods and environments can help reduce flare-ups.
