Plaque is a gluey film of bacteria, food debris, protein cells and dead skin cells which coats the teeth and gums and which provides the medium for bacterial growth. It plays a pivotal role in the development of tooth decay, dental calculus, and periodontal and gingival (gum) diseases.

It can be hard to remove all of the sticky white deposits known as plaque, particularly from difficult to reach areas of the mouth; around the back molars and in between the teeth. As a result this plaque bacteria builds up on the teeth and gums, which can lead to localised gum disease – the first sign of which is bleeding.

Frequent and thorough brushing and flossing using a good technique is important, because the composition of the plaque changes as it ages, so it is important to remove as much of it as possible, as soon as possible. Mouth rinses can get rid of the bacteria that causes plaque, gingivitis, and bad breath so it is a good idea to have a good swish after brushing and flossing.
