Painful infection and ulceration of the gums due to abnormal growth of bacteria that usually exist harmlessly in small numbers in gum crevices. Predisposing factors include poor oral hygiene, smoking, throat infections, and emotional stress. In many cases the disorder is preceded by gingivitis or periodontitis. The condition is uncommon, primarily affecting people aged 15–35. The gums become sore and bleed at the slightest pressure. Crater-like ulcers develop on the gum tips between teeth, and there may be a foul taste in the mouth, bad breath, and swollen lymph nodes. Sometimes, the infection spreads to the lips and cheek lining (see noma). A hydrogen peroxide mouthwash can relieve the inflammation. Scaling is then performed to remove plaque. In severe cases, the antibacterial drug metronidazole may be given to control infection.
