4. Whiter teeth
A broad smile can be very attractive but at the same time if you have yellow dirty teeth then people may run the opposite way after seeing you. You can use baking soda to make your smile more attractive and the teeth whiter. Mix 6 teaspoons of baking soda, a third teaspoon of salt and 4 teaspoons of glycerin. Mix this solution with 15 drops of breath freshening oil such as peppermint then brush your teeth with it. You will have whiter teeth and can smile more freely!
