Cosmetic dentistry is essentially a procedure to remove stains and pigment from tooth enamel and dentin.
Depending on the color of the teeth and the cause, there are different ways to whiten them.
There are generally four types: First, ultrasonic cleaning. For that kind of normal tooth surface stains, as long as the pollutants are removed, the teeth can be restored to white, and the teeth can be washed once every six months.
In addition, you can usually choose toothpaste with teeth whitening function, and pay attention to less smoking and drinking less colored beverages.
The second is the drug rinsing method, which is mainly suitable for mildly pigmented teeth, enamel hypoplasia, and yellowing of teeth caused by age-related changes in enamel.
It is less effective for tetracycline teeth and yellow die teeth with heavier color, because only the surface layer becomes white, which is not durable. At present, there are hydrogen peroxide decolorization, comprehensive decolorization, etc. Generally, the price of such products abroad is about half more expensive than that in China.
The specific method is that the doctor first makes a dental tray according to your tooth shape, and then puts the bleaching solvent into the custom-made dental tray every night before going to bed, and wears it on the teeth to achieve the bleaching effect of gradually removing stains.
The drug has a low risk of depigmentation, has a quick effect, and takes about three weeks to treat. Clinical practice has proved that bleaching agent has no damage to gums and pulp, as long as it is safe, convenient and effective to bleach under the guidance of a dentist. The third is photosensitive veneer.
Veneers are a layer of material similar to normal tooth color pasted on the surface of stained teeth to cover the color on the teeth. Nowadays, resin materials are widely used, but because the resin itself is translucent, it has a good effect on moderately colored teeth, but it is not optimal for severe tetracycline teeth.
Photosensitive veneers can be kept for several years, but they are easy to fall off, easy to discolor, cause gingival swelling, and bleeding.
However, because of its low price and simple and convenient operation, it is still used in China. In addition, porcelain veneer is currently being promoted in China, and its advantages are that it can completely cover the pigment, is durable, beautiful and realistic. The fourth is porcelain.
If you wish you could smile brighter, try it. Porcelain is the most effective and longest-lasting method and can be used for decades. It is mainly suitable for severe cases of moderate and severe tetracycline teeth, yellow die, enamel hypoplasia, cracked, incomplete and pitted teeth.
