Scaling and polishing is a procedure that involves the removal of plaque and tartar from the teeth, through professional teeth cleaning. Your mouth is constantly bathing in saliva, which contains calcium that help to strengthen and protect your teeth. While this is good for teeth, if you fail to maintain good oral hygiene regimes, the calcium can build up around teeth, leaving a chalky substance on your teeth.
If this chalky substance is allowed to accumulate on the teeth, it will provide a breeding ground for bacteria on the gums. The purpose of cleaning and scaling and polishing is to smoothen the tooth enamel, making it resistant to sticky plaque and bacteria, allowing you to keep your teeth cleaning with regular home care.
