You’re probably thinking what tooth decay is?
Tooth decay happens when acids wear away the tooth’s enamel. These acids are made by a sticky film called plaque.
Plaque build up on teeth has germs that feed on sugary foods. The process of digesting these sugars makes acids that attack tooth surfaces.
Over time, tooth decay can cause holes in the tooth surface. These are called tooth cavities. If left untreated, cavities can get bigger. They can even destroy the tooth.
Acids constantly attack your tooth surfaces, but tooth decay doesn’t happen all at once. That’s because other elements in your mouth work to strengthen your teeth and stop the tooth decay process. One of these elements is saliva. Saliva has minerals that help strengthen tooth surfaces. Fluoride, a natural mineral that is often added to water and found in toothpaste, also helps to make teeth stronger.
