Fluoride vs plaque Plaque: the dirty story Plaque is the sticky, soft layer that forms on teeth every day. If left to build up, plaque causes tooth decay and gum disease. Bacteria in plaque reacts with sugar to produce an acid that dissolves the minerals in teeth; over time this causes cavities (holes). Cavities can cause pain and discomfort and will eventually need dental work. Brushing with a fluoride toothpaste, a healthy diet, regular check-ups and preventive treatments provided by dental therapists and dentists help stop plaque build-up and cavities. Protecting our teeth Fluoride is an important weapon in the war against plaque. It is a natural element found in air, soil, fresh water, sea water, plants and lots of foods. Most of the fluoride we eat or drink comes from water, food and toothpaste. Fluoride in food, drink and our saliva continually washes over the teeth to help protect them.

Fluoride helps protect our teeth from tooth decay in two main ways: it strengthens growing teeth it can help fix the very early stages of decay in all teeth.
