Why is scaling and cleaning necessary?
Every day bacteria begin to build up in your mouth, sticking to your teeth and gums and forming what is called a plaque biofilm. Teeth are not always perfectly shaped. So sometimes, when you are cleaning them, you do not always manage to reach into every nook and cranny,especially at the back, where food always seems to get stuck in a gap between your teeth.
This weak spot is exactly the sort of spot where the bacteria that attack your teeth can gather.Throughout the day, plaque builds up all over your teeth. Plaque is the sticky film, full of bacteria, that turns into acid when it reacts with the sugary foods you eat. If it is allowed to build up, the bacteria in it can cause gum disease, making your gum bleed, become sore and infected. The purpose of the cleaning
and polishing is to leave the surfaces of the teeth clean and smooth so that bacteria are unable to stick to them and you have a better chance of keeping the teeth clean during your regular home care.
