Your hygienist or dentist will clean your teeth during your check-up appointment. A dental cleaning is a preventative treatment that involves manual removal of plaque using special hand tools and/or use of a tool called an ultrasonic scaler that helps remove excessive calculus/plaque and any staining. Your hygienist or dentist will polish the enamel surface of your teeth for a beautiful smile. Fluoride is a mineral that helps prevent cavities and repair teeth in early stages of gum disease. Children under 16-18 years should have fluoride for developing and strengthening teeth and adults should be elevated if they have a risk for developing cavities and decay.
