As we all know, teeth are an important tool for us to chew food. If we don't have teeth, even eating is a problem, and the body medium needs to be supplemented with some necessary nutrients and other elements, which can only be extracted from the food we eat, so we should eat it every day, which is also a normal reaction of human function. If we don't eat, we will feel hungry.
But after eating, there will be a lot of food left on the teeth, which is harmful to the teeth after a long time. So now we see more and more people washing their teeth. In fact, if they often wash their teeth, they will destroy the protective film on the surface of their teeth, and many cleaners used are composed of different chemical elements, so if they often wash their teeth, they will destroy the original protective film and do some harm to the teeth themselves.
I believe everyone has had this experience, that is, if you don't pay attention to the cleaning of your teeth, it will lead to yellowing and blackening of your teeth, and a large number of dental calculus will be attached to your teeth. After a long time, it is likely to lead to the phenomenon of teeth falling off slowly. Therefore, it is very necessary to go to the relevant hospital regularly to do some tooth washing work, but it is best not to wash it often. That's all I've summed up about tooth washing.
