Your Gums

Bleeding gums during flossing is a common concern, but it’s often misunderstood. Many people assume that flossing itself is causing the problem, when in reality the bleeding is usually a sign of inflammation already present in the gums. When plaque— a sticky film of bacteria—accumulates between the teeth and along the gumline, the body responds with irritation and swelling. This early stage of gum disease, known as gingivitis, makes the gums more sensitive and prone to bleeding with even gentle cleaning.

If you haven’t flossed regularly, the gum tissue becomes fragile, similar to how an unused muscle becomes weak. When you begin flossing again, the tissue may bleed for a few days as it adapts. With consistent daily flossing, the inflammation typically decreases, the tissue strengthens, and the bleeding stops. This improvement is often one of the first signs that your gums are healing.

However, persistent bleeding can signal a deeper problem such as advanced periodontal disease, systemic inflammation, vitamin deficiencies, or medication effects. In these cases, professional evaluation is essential. Understanding why gums bleed empowers patients to respond appropriately—by improving home care, keeping regular dental visits, and seeking timely treatment to protect both oral and overall health.
