Necrotising ulcerative gingivitis

Description

Necrotising ulcerative gingivitis (NUG) is a condition affecting the gums that is caused by a bacterial infection. It is a form of periodontal (gum) disease. But unlike other forms, it typically develops quickly and causes moderate to severe pain. "Necrotising" means that the condition destroys tissue. "Ulcerative" refers to sores that can appear on the gums.
