In our office, professional dental cleanings are usually performed by Dental Hygienists. Your cleaning appointment may include a dental exam, bite wing x-rays, topical fluoride application, removal of plaque, removal of calculus, and teeth polishing. Plaque and calculus are bacterial deposits on teeth. The difference between them is one of texture. Calculus refers to hard deposits and plaque refers to the soft deposits on teeth. Our dental hygienists are experts at oral hygiene and will instruct you in proper tooth brushing and dental flossing technique.
