Scaling involves the removal of plaque and tartar deposits that build up on your teeth over time, while polishing is the removal of stains left by substances like coffee, tea or tobacco.

Plaque is a pale yellow substance that develops naturally on teeth. As more and more bacteria colonises the plaque layer, it becomes thicker, and gives the furry feeling when your tongue touches your tooth surface.

If left alone for more than 48 hours, plaque will mineralise to form calculus, which is hard and sticks onto the tooth surface. Tooth brushing alone would be insufficient to remove calculus and it can only be removed by professional scaling and polishing. Calculus left on the tooth structure will eventually lead to gum disease and tooth decay.

It is recommended to have a 6 monthly scale and polish, done by a dental professional, to help you maintain healthy teeth and gums.
