How to choose cold light whitening, porcelain whitening and veneer whitening Have you ever been disliked for yellow teeth?
Dare not open your mouth for fear of affecting your image?
Not to mention ugly, girls can’t put on lipstick properly, red mouth and yellow teeth, it’s like scrambled eggs with tomatoes!
I believe that we still have a certain understanding of the method of tooth whitening.
At present, there are three ways of whitening on the market: cold light whitening, porcelain teeth whitening, veneer whitening.
But how exactly, and what are their advantages?
What are the shortcomings?
Is it really for me?
After reading today’s article, I believe you will choose a suitable way for your teeth.
1, cold light whitening known as fast and safe tooth whitening technology.
Principle: Low temperature cold light to avoid the treatment of dental nerve irritation.
The main component of whitening agent is hydrogen peroxide.
Apply a layer of protectant to the gum edge, then apply whitening agent to the tooth surface. Shine a cold light (8 to 10 minutes depending on the degree of tooth staining), remove the whitening agent, and apply a new layer of whitening agent.
The process was repeated three times and lasted only 30 to 40 minutes.
Suitable disease: mild exogenous pigment teeth (coffee, tea stains, smoke stains deposition), mild tetracycline teeth, etc.
Duration: About two years.
Advantages: Cold light tooth whitening technology, its effect can be increased by 5 color levels to 14 color levels;
The use of low temperature cold light, avoid the process of operation to the dental nerve damage;
The operation process does not touch the gums at all and will not cause damage to the tooth structure.
Shortcomings: The cold light whitening is still through the bleaching drugs to whiten teeth, laser is only to improve the speed of decolorization.
In the process of operation, the teeth feel sore. It is because the bleach has damage to the enamel on the tooth surface, and there is a greater chance of dentin allergy (cold and hot reaction) and even tooth embrittlement.
Improper manipulation, but also easy to cause teeth cold and hot allergy, gum swelling.
2, porcelain teeth whitening if you have a tooth defect and want to whiten, choose porcelain teeth is very appropriate.
It is also the dental prosthesis with the best density and the closest color effect to the natural color.
Because the bacteria on the surface of porcelain teeth can not live, so in addition to the whitening effect, there will be no cavities.
Suitable disease: Suitable for moderate and severe tetracycline teeth, dental fluorosis, enamel hypoplasia, tooth cracks, incomplete and other serious cases, whitening effect is obvious.
The theory is that if your gums are healthy, with good daily care (which is hard to do), they can last a decade or even a lifetime.
Advantages: Whitening teeth obvious effect, more white can be, more lasting and even once and for all oh.
If you have serious tooth defects or small teeth, porcelain teeth are more appropriate.
Disadvantages: However, if you simply want to change the color, the original teeth must be ground down first, which will cause irreversible damage to the teeth.
Teeth that are shaped like rods are very fragile.
After a period of time, gingivitis, periodontitis, and gingival atrophy are more likely to occur.
3, veneer whitening principle: veneer whitening is to stick a layer of veneer on the tooth surface, cover tooth defects, color change, etc.
Now popular dental veneer can be divided into resin veneer and porcelain veneer two kinds.
Both of them remove part of the tongue and attach a veneer to the tooth to keep the shape of the tooth the same.
In contrast, porcelain veneers are much lighter and lighter, and can be used to grind little or no teeth.
Suitable diseases: tetracycline teeth, dental fluorosis, melon seed teeth and hereditary yellow teeth, melon seed teeth, tooth defects, teeth too small, etc.
Duration: the resin veneer will age and need to be replaced after a few years;
Porcelain veneers should theoretically last ten years.
Advantages: Compared with resin veneer, porcelain veneer has good color, good shape, almost no difference with real teeth, its production process is very fine, not only can whiten teeth, but also the main method to treat tooth defects and dentition loss.
Deficiency: Relatively high enamel requirements, if your enamel defect is more than 70% is not recommended to do porcelain veneer.
Due to the light and light properties of porcelain veneer, for some teeth with darker colors, whiter color levels are needed to achieve the effect of shading.
