Whenever i brush my teeth my gums bleed, what is going on?

Gingivitis: Gingivitis is the beginning of periodontitis or gum disease. It is caused by bacteria that accumulates under the gum tissues and between the teeth. If left un treated, the bacteria can cause bone loss and eventually tooth loss. Seek a professional dental cleaning and begin flossing daily along with your brushing to help stop the bleeding.

Gingivitis or worse: Bleeding gums is a sign of inflammation. You need to get a professional exam and treatment. Call your dentist.

Periodontist: Sounds like you have gum disease. See a gum specialist, a periodontist, for the best quality conservative treatment.
