It is caused by bacteria build-up in our mouths that attack the hard tissues of the tooth. It’s not a disease one is born with. It is mainly caused by improper oral hygiene. Bacteria that you don’t remove from the surface of your teeth by brushing them regularly form a textured substance also called plaque. It sticks firmly to the tooth and its subsequent removal is not easy. mproper tooth brushing and neglect of plaque removal causes demineralization and therefore decalcification. It is through demineralization that a chalky white stain forms and the tooth enamel becomes brittle. But nothing is yet lost at this stage. If you manage to keep the tooth clean, without letting more bacteria form, the decay can be stopped and the enamel can remineralize.

However, if the bacteria start to spread more rapidly, the decay will continue deeper into the dentine and will subsequently change its colour to have brown or even slightly black spots. It’s important to remember that even a tiny cavity in your tooth can cause big problems!
