Your smile is an essential part of your personality. The brighter and better you smile, the more confident you appear. But, if your teeth are not white, have stains or are discolored, then you may think twice before flashing a wide smile to anyone.
Teeth get yellow due to several reasons like not taking good care of them, too much consumption of coffee, cola, tea, tobacco, and other such products (1).Due to these, a thin coating is developed over the enamel.
