In order to whiten and strengthen the teeth at home, you need to take a pinch of sea salt, thoroughly rub it in fine powder and add 2-3 drops of high-quality vegetable oil (preferably olive). Mix thoroughly, dip the index finger of the hand and thus brown your teeth and gums for 5 minutes. Thanks to sea salt and oil, not only teeth will be whitened, but periodontal disease and bleeding gums will also leave.
