The most common reason for bleeding gums is inadequate plaque removal from the teeth at the gum line. This leads to inflamed gums, a condition known as gingivitis. If plaque is not removed through regular brushing and care by a dentist or oral hygienist, it will harden into what is known as tartar. Ultimately, this will lead to increased bleeding and more advanced gum and jawbone problems.

Some other things that can cause gums to bleed during regular brushing include hormonal changes during pregnancy, brushing too hard or with too hard a toothbrush, improper flossing or any bleeding disorder.

If you notice your gums bleeding when you brush chances are it’s just time to see your dentist.
