External discolouration are caused by the consumption of staining substances like tea, coffee, colas, pan, pan masala, supari, tobacco, smoking etc. these discolourations are easy to remove and teeth becomes lighter quickly.
Internal discolorations occur due to disturbance in the structure of the tooth.
