What exactly in trench mouth. Can it be treated with an antibiotic? Can a child get it who they regularly brush their teeth?

"Trench mouth” is a noncontagious infection and ulceration of the gums. The term comes from World War I when the condition was common among soldiers in the trenches. Symptoms include painful, red, bleeding gums, bad breath, difficulty swallowing, a bad taste in the mouth, and excessive saliva. Occasionally, fever may be present or lymph nodes of the head and neck may be swollen. It appears as crater-like ulcers in between the teeth covered with a gray membrane on the gums. Trench mouth is caused by the abnormal growth of bacteria normally living in the mouth. Poor nutrition, an illness that lowers resistance, tooth or mouth infections, stress, smoking, and poor oral hygiene contributes to the bacteria’s growth. Treatment consists of good oral hygiene. Thorough tooth brushing and flossing must be started as often as possible. Salt water rinses will help soothe the sore gums. Hydrogen peroxide, used to rinse or irrigate the gums, is often recommended to remove decayed gum tissue. Over-the-counter pain relievers will help reduce discomfort. Antibiotics may be given if there is a fever. Left untreated, complications include spread of the infection to the cheeks, lips, or jawbone, loss of teeth, and chronic gum disease. Trench mouth can be prevented by maintaining good oral hygiene and regular flossing as well as regular professional dental cleaning and examination. The condition is usually curable within a month of starting treatment.
