Trench mouth is a severe, painful form of gingivitis characterized by bad breath, bleeding gums and open sores. Also called acute necrotizing ulcerative gingivitis or Vincent's stomatitis, trench mouth is a rare sight in this day and age.
Thorough tooth brushing and flossing must be done as often as possible, preferably 3 to 4 times a day. Saltwater rinses may be soothing to sore gums. Diluted hydrogen peroxide (equal parts 3% hydrogen peroxide and water) or chlorhexidine can be used to rinse the gums and remove decayed gum tissue. The disorder can be quite painful until it is treated. Since trench mouth involves bacteria, antibiotics are normally prescribed into to destroy the bacteria as well as prevent any infection from spreading. If there is any extensive damage, the individual may need surgery to help heal this damage.
