If gingivitis is left untreated, the infection will eventually get into the roots of the teeth. The plaque on the root of the tooth and along the gums infects all of these areas. This is a type of gingivitis. The symptom of trench mouth is heavy bleeding of the gums. It is caused by a bacterial infection, but is not contagious.
Treatment entails antibiotic mouthwashes and cleaning off of tartar from the teeth.
Gum surgery may be necessary in rare cases in order to save the teeth. This will keep plaque to a minimum. Having a biannual cleaning from your dentist is a great way for most people to help prevent gingivitis, because they have special tools to scrape away plaque and tartar. Use an antibacterial mouthwash. Repair misaligned teeth to keep food from getting trapped between teeth.
