Every day, some microorganisms are attached to the surface of teeth, mainly because of some bacteria and food residues. Although brushing your teeth every day can remove some dental plaque, with the accumulation of time, dental calculus will gradually form under the action of bacteria, and brushing your teeth can not be removed, so you can only wash your teeth.
At present, most dental clinics and hospitals use ultrasonic tooth cleaning, because the ultrasonic tooth head has no destructive effect and can remove dental calculus from the teeth. Doctors will move slowly and gently during the operation, so don't worry, there will be other side effects after tooth cleaning.
In fact, many people have misunderstandings about the color of teeth. Many people think that healthy teeth are pure white, just like the teeth of models in toothpaste advertisements. Actually, this is not right. The structure of normal teeth is a layer of transparent enamel containing light yellow dentin, so some dentin color can be revealed, so the color of normal teeth should be slightly yellow. Especially white and opaque teeth usually give people an unreal feeling.
In daily use, there must be some pigments accumulated on the surface of teeth, which makes the color of teeth look more unsightly. An important goal of tooth washing is to remove these pigments to the greatest extent, so after perfect tooth washing, because these dyed pigments are well removed, the teeth will show their own color, that is, light yellow.
Generally speaking, teeth will turn white to some extent after washing. However, as a means to prevent and treat periodontal disease, the effect of tooth washing on tooth whitening is extremely limited. Patients can improve the appearance of teeth more significantly through other methods, such as cold light whitening and aesthetic restoration.
