5. Brighten your smile
For those who have had their teeth professionally whitened, you know how expensive this service can be. Even when purchasing whitening strips, they are a bit of an investment — and who knows what’s in them. At an average cost of $40 for 14 treatments, there has to be a better way, right?
Once again, baking soda can come to the rescue. When you combine 1 to 2 large strawberries and 1/2 teaspoon of baking soda, you can create a solution that will remove surface stains for less than $0.30. The baking soda will help remove surface stains while balancing your mouth’s pH, whereas the strawberries offer an enzyme known as malic acid, which also break down surface stains.
