Our teeth are susceptible to change colour due to the food we eat, the water we drink and many other factors. When we are babies our teeth are white and bright but as we get older our teeth change colour and become brown. The phenomena have led to the development of teeth whitening.
Some factors result in teeth changing colour. The biggest contributor to this process is the food and drink we take in. They have intense colour pigments which discolour the teeth as they attach to the outer enamel of your tooth. These pigments are called chromogens.
