Although I brush my teeth every day, I find that I don't brush deeply at all, and my teeth are not as white as before. What should I do?

Just like an advertisement! Does everyone use Philips sonic vibration toothbrush? As long as you choose the right toothpaste and toothbrush, brush your teeth correctly, brush your teeth at least twice every morning and evening, rinse your mouth after meals, eat less or try not to eat snacks and sweets, smoke less and drink less coffee, and adhere to good oral hygiene habits, your teeth will gradually turn white. If yellow teeth and black teeth are caused by local water quality, brush your teeth with cold white water. If the fluorine content in water is high, choose fluoride-free toothpaste. Some people are used to brushing their teeth with water, which is wrong. Adding water weakens the friction and cleaning effect of particles in toothpaste, and the effect of dry brushing toothpaste will be better. If you really want your teeth to be bright and white, go to the hospital to have your teeth cleaned regularly. The whiter the teeth, the better. Healthy natural teeth are the best. I hope your teeth turn white, your teeth are good, your appetite is good, your food is delicious and you are in good health.
