Why is it Necessary to get a Dental Cleaning by a Dentist?

Dental cleanings involve removing plaque (soft, sticky, bacteria infested film) and tartar (calculus) deposits that have built up on the teeth over time. Your teeth are continually bathed in saliva which contains calcium and other substances which help strengthen and protect the teeth. While this is a good thing, it also means that we tend to get a build-up of calcium deposits on the teeth. This chalky substance will eventually build up over time, like limescale in a pipe or kettle. Usually it is tooth coloured and can easily be mistaken as part of the teeth, but it also can vary from brown to black in colour.

If the scale, or calculus (tartar, as dentists like to call it) is allowed to accumulate on the teeth it will unfortunately provide the right conditions for bacteria to thrive next to the gums. The purpose of the cleaning and polishing is basically 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.

Also it leaves your teeth feeling lovely and smooth and clean, which is nice when you run your tongue around them. The professional cleaning of teeth is sometimes referred to as prophylaxis (orprophy for short). It’s a Greek word which means “to prevent beforehand” – in this case, it helps prevent gum disease.

What do they use to clean the teeth? 

Commonly used first is an ultrasonic instrument which uses tickling vibrations to knock larger pieces of tartar loose. It also sprays a cooling mist of water while it works to wash away debris and keep the area at a proper temperature. The device typically emits a humming or high pitched whistling sound.

The ultrasonic instrument tips are curved and rounded and are always kept in motion around the teeth. They are by no means sharp since their purpose is to knock tartar loose and not to cut into the teeth.

They also have a suction tube, that will not interfere but just suck out the liquid in your mouth. This means you need not wash your mouth every now and then.
