The only products you’ll need are aluminum foil and soda. First of all, cut large enough pieces that will cover your teeth.
Add a little water to the soda to turn it into a paste.
Place the mixture on the aluminum foil and then wait 60 minutes. If you repeat this procedure 2 times a week, your teeth will gain a whiter shade. With a little patience you’ll be able to boast about your beautiful teeth in a short time and for little money.
