Many beverages can leave dark stains, which are not appealing. It is particularly true if you consume black coffee or black tea too frequently. This problem can be solved without spending a lot of money on expensive tooth whiteners. Instead, get some baking soda. It's simple. Apply this mixture to your teeth by mixing 1/4 teaspoon baking soda and water. This mixture can be applied with a toothbrush. After applying the mixture, rinse your mouth thoroughly.
