One middle-sized lemon
A pouch of baking soda
A cotton ball
Preparation and application:
First, cut the lemon in half and squeeze the juice from the both halves into the bowl. Then, add the baking soda and mix the two ingredients well with the spoon. Next, soak the cotton ball into the mixture and start applying it onto your teeth. Rinse the teeth gently with the cotton ball for 3 minutes and then leave the mixture on for 1 more minute. Then, rinse the mouth with water, wait for 10 to 20 minutes, and then wash the teeth with regular toothpaste.
Repeat the procedure twice per week for optimal results.
