Gum disease begins when plaque and inflammation affect the tissues supporting the teeth. Early gingivitis may be reversible, while periodontitis can damage bone and requires professional care.

When to contact a dentist

Contact a licensed dentist when you notice pain, swelling, bleeding gums, sensitivity, a broken tooth, a loose restoration, or any persistent change in your mouth. Seek urgent professional care for severe swelling, facial trauma, uncontrolled bleeding, or difficulty breathing or swallowing.
