Do the new whitening toothpastes and chewing gums actually work?
No. Being over the counter products, the concentration of the whitening element is much lesser than what is actually used by dentists. If you really want white teeth, visit the dentist. Does brushing your teeth too much erode the enamel? Yes. If you brush in the wrong direction, then you are harming the enamel of your teeth. It is advisable to brush vertically and not horizontally. Using an electric toothbrush is more effective than using a hand brush. Also, the bristles of the brush should be soft so that it does not erode the enamel. Is brushing with a neem datum (twig) better than using a toothbrush and toothpaste? No. Neem datum is not advisable as it has bristles with irregularities, which can your gums. Does brushing with salt whiten the teeth? No. Salt is abrasive and can cut the gums, and since it is rough it can rub away the outer most layer of the tooth. The inner layers of the teeth are yellow. So the more you remove the enamel, the more yellow your teeth will become. Is ble
