To understand why gums bleed, it helps to understand how gum tissue works.
Your gums form a protective seal around each tooth, helping keep bacteria from reaching the structures that support your teeth.
But when plaque and bacteria build up along the gumline, the body responds with inflammation.
This inflammation causes many of the early symptoms people notice: redness, tenderness, swelling, and bleeding when brushing or flossing.
In the early stages this condition is known as gingivitis, the first stage of gum disease.
The good news is that gingivitis is often reversible when addressed early.
However, dentists say brushing harder alone isn’t enough. For gums to recover, the irritated tissue must be calmed and supported so it can gradually return to a healthier state.
That’s why newer approaches to gum care focus not only on cleaning teeth, but also on supporting the gum tissue itself.
