Tooth yellowing with these four methods to whiten a white tooth is very beautiful, but we can not blindly pursue the whitening effect, according to their own tooth condition to choose tooth whitening method.
Let’s take a look at how to whiten teeth.
The ingredient of COLA is syrup and carbon dioxide gas, drink too much, can make sugar calm in the tooth surface, make its color black.
A study found that if you drink one litre of cola a day, half of the enamel on your teeth will be eaten away by acid after two years.
Among carbonated drinks, dark colas are the most damaging to teeth, followed by orange soda. Generally speaking, the lighter the drink, the safer it is. It is recommended that you choose clear Sprite!
Dental experts from the World Health Organization (WHO) believe that once a year is enough for the average person, as long as they pay attention to the cleaning of their teeth. If you are a regular smoker, you need to clean your teeth 2-3 times a year.
Experts point out that too much cleaning can make the gap between the teeth enlarged, the teeth are allergic, food residue and color easily attached to the tooth surface.
Turmeric, the main ingredient in curry, has overtaken nicotine as the No. 1 influence on tooth color, according to the American Dental Association’s latest “tooth staining” list.
Turmeric has an almost irreversible staining effect on teeth, making it a veritable ‘white tooth killer’, according to the study.
If you really like the spiciness, I suggest you choose green curries with the weakest staining force and avoid red and yellow curries with the strongest staining force!
4 Common tooth whitening Methods 1. Cold light whitening technology is a new type of tooth whitening and restoration method.
Cold light whitening is to use low temperature cold light irradiation, so that the teeth surface whitening agent solidification, and then peel off whitening agent, so that pigments, dental stones and other substances will fall off, so as to achieve the effect of whitening teeth;
This METHOD IS NOW THE most popular, its operation is simple, there is no damage to the tooth, and the whitening effect is natural, beautiful, it is the price is higher.
2. Drug bleaching tooth bleaching is the best for formal orange and brown discoloration teeth. It has the best effect on yellowing teeth aggravated with age, moderate effect on mild tetracycline teeth and dental fluorosis, and poor effect on severe tetracycline teeth and dental fluorosis, because it can only be the surface whitening, not durable;
But THIS KIND OF METHOD IS SAFE, CONVENIENT, AND WON’T HAVE DAMAGE TO GINGIVA AND DENTAL PULP, BEAUTIFUL WHITE EFFECT LOOKS PRETTY NATURAL ALSO.
3, tooth veneer tooth veneer is to paste a layer of approximately normal tooth color material on the surface of the stained teeth, to cover the color of the teeth, but because the resin itself is translucent, so the effect of moderately colored teeth is good, for serious tetracycline teeth can not reach the best ideal;
Photosensitive veneer can be maintained for several years, but easy to fall off, easy to discolor, cause gum swelling, bleeding and other shortcomings;
But IT BECAUSE THE PRICE IS CHEAP OPERATION IS CONVENIENT AGAIN, SO STILL HAVE a LOT OF PEOPLE TO USE, HOWEVER ITS WHITENING EFFECT LOOKS TO DO NOT HAVE ABOVE TWO KINDS OF NATURE.
4. The outer layer of porcelain teeth is made of high temperature resistant and low solubility porcelain powder similar to the natural teeth, and the inner layer is a gold sleeve synchronized with the hot and cold expansion of the teeth. It is made by burning and melting in a vacuum high temperature porcelain oven, and the finished teeth have smooth surface, stable color and wear resistance.
It has to be worn down to make the teeth smaller, so it’s more damaging to the teeth, and it’s relatively expensive. The whitening effect is good, but it’s not natural to look at, because it’s a denture after all.
