Cosmetic dentistry is essentially a procedure to remove stains and pigments from tooth enamel and dentine.
According to the depth of the tooth color, the cause of formation, take different ways to whiten.
Generally, there are four kinds: one is ultrasonic cleaning.
For the normal tooth surface stain, as long as the pollutants are removed, the tooth can be restored to its own color, tooth cleaning can be washed once every six months or so.
The second is the drug rinsing method, which is mainly suitable for mildly pigmented teeth and enamel hypoplasia, and the tooth color yellowing caused by enamel change due to aging.
On the color of heavy tetracycline teeth, yellow teeth and other effects are poor, because only the surface white, not durable.
At present, there are hydrogen peroxide decolorization, comprehensive decolorization, and so on. Generally, the price of such products abroad is about half of the domestic price.
The doctor first makes a denture holder according to your tooth shape, and then puts bleaching solvent into the customized denture holder every night before going to bed, and puts it on your teeth to gradually remove the bleach effect.
The drug has little risk of decolorization, is quick to take effect, and takes about three weeks to treat.
Clinical practice has proved that bleach is not harmful to gums and pulp, as long as bleaching under the guidance of the dentist is safe, convenient and effective.
The third is photosensitive veneer.
Veneer is to paste a layer of approximately normal tooth color material on the surface of the stained tooth to cover the color of the tooth.
Resin material is more widely used now, but because the resin itself is translucent, so the effect of moderate colored teeth is good, to serious tetracycline teeth and so on 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.
However, because of its low price, simple and convenient operation, it is still used in China.
In addition, porcelain veneer is being promoted at home at present, its advantage is to be able to cover pigment completely, sturdy and durable, beautiful and realistic.
Fourth, the beauty crown.
If you want a bigger smile, go for it.
Cosmetic crowns are the best and last the longest, lasting for decades.
It is mainly suitable for moderate and severe tetracycline teeth, yellow die teeth, enamel hypoplasia, teeth with cracks, incomplete, serious cases of holes.
