Our teeth are made up of two parts. The inner part is made up of a calcified tissue called dentin. Dentin has microscopic channels which reach out to the enamel. The enamel is the outer most part of the teeth. It protects the teeth. A layer forms over the enamel when we eat something. Stains are formed when particles remain in the microscopic cracks in the enamel or dentin. Extrinsic stains are formed on the outer layer of teeth and can be easily removed by brushing. However, intrinsic stains are formed inside the teeth. Thus these stains cannot be removed by brushing.
