Dental cleaning/scaling is one part of oral hygiene, in which the hygienist or dentist remove plaques, cleans the gums of build-up. Scaling is done to prevent cavities, gingivitis and other periodontal disease. The procedure isn't painful though it may feel sensitive to patients who have not had a cleaning in a long time or just have a lot of build-up. Scaling time will be determined by the hygienist or dentist after determining amount of build-up/plaque. After the cleanings each and every patient will receive an oral hygiene bag with toothbrush, toothpaste, floss in order to keep up your daily dental hygiene.
Cleanings/Scalings are measured in units with each unit being 15 minutes. For example if a hygienist or dentist says that you need 4 units then that would be 1 hour of cleaning/scaling. The same measurement applies for insurance company policies.
