Psoriasis is a chronic inflammatory skin disease and people with psoriasis may have other diseases as well.

It is unknown why people fall ill but probably involves family history and environmental factors, such as stress, nutrition, infection, excessive alcohol intake and obesity. The suggested connection with gum disease is thought to be explained by the increased inflammation in the blood.

Professional treatment of gum disease and good oral hygiene will result in a healthier mouth with less inflammation, which is a benefit to everyone.
