How to Whiten Teeth With Baking Soda (17 Methods)

Yellow or stained teeth can often be embarrassing. They can be caused by many things such as unhealthy oral hygiene, indulging in excessive tea, coffee or tobacco chewing, acidic drinks, smoking, certain medication and illness.
Our teeth are coated with a shiny protective shield known as enamel. Below this is a yellow layer known as dentin. Excessive intake of certain foods strips the enamel layer revealing the dentin below.
