Before the actual cleaning process begins, dentist/dental hygienist start with a physical exam of your entire mouth and check around your teeth and gums for any signs of gingivitis (inflamed gums) or other potential concerns.
During an oral clean a dentist or a hygienist uses dental instruments to clean dental calculus from in between your teeth and around the gum line.
Dental calculus is plaque in the mouth that has hardened around the teeth. For most people it is recommended that a dental clean is performed 6-12 monthly.
This is because although calculus occurs less in people with good oral hygiene (flossing and brushing) calculus cannot be fully prevented and once calculus has built up it can only be removed with a professional clean using dental instruments. This process is crucial in assuring that your teeth and gums remain healthy and free from gingivitis and periodontitis.
