Regular dental cleans are important in maintaining exceptional oral health by removing any plaque and calculus deposits that may have built up over time. Calculus (also known as tartar), is plaque that is hardened and bonded to the teeth which is impossible for you to remove with your toothbrush. Ensuring this build up is removed at least every 6 to 12 months will help keep your gums healthy and reduce your risk of gum disease.
