If your gums are bleeding, please call our team or book an appointment. Whilst bleeding gums are common, it's important to check the cause to rule out any serious conditions. In general, bleeding indicates that your gums are inflamed, and this inflammation is generally responding to bacteria on the surface of your teeth. The surface inflammation is known as gingivitis, but may also arise from an incorrect brushing technique, improper flossing, oral cancers and more.
