Check your teeth in the mirror. Have you ever been accused of having yellow teeth?
Have you ever been afraid to open your mouth for fear of affecting your image?
Red lips and yellow teeth, it is scrambled eggs with tomatoes!
Let’s talk about tooth whitening ~ First, let’s start with the whitening method ~ At present, there are three kinds of whitening methods in the market: cold light whitening, porcelain whitening and veneer whitening.
But how exactly, and what are their advantages?
What are the shortcomings?
Is it really suitable for you?
After reading the following content, I believe you will find a suitable way to improve your teeth.
First, cold light whitening known as fast and safe tooth whitening technology ¡ú principle Low temperature cold light to avoid the stimulation of the dental nerve in the treatment process.
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.
¡ú Suitable for mild exogenous pigment teeth (coffee, tea stains, smoke stains deposition), mild tetracycline teeth, etc.
¡ú It lasts about two years.
¡ú Advantages of cold light tooth whitening technology, its effect can be improved 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.
In fact, the cold light whitening is still through bleaching drugs to whiten teeth, laser is only to improve the speed of decolorization of drugs auxiliary tools.
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.
Second, porcelain teeth whitening density is the best, the color effect is the most close to the natural color if you have tooth defects and want to whiten, choose porcelain teeth is very appropriate.
Because the bacteria on the surface of porcelain teeth can not live, so in addition to the whitening effect, there will be no cavities.
¡ú 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.
¡ú The advantage of whitening teeth is obvious, to more white can be, more durable can even be once and for all oh.
If you have serious tooth defects or small teeth, porcelain teeth are more appropriate.
But if you simply want to change the color, the original teeth must be ground down to make porcelain teeth, 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.
Veneer whitening teeth veneer can be divided into resin veneer and porcelain veneer ¡ú Principle veneer whitening is to stick a layer of veneer on the tooth surface, cover tooth defects, color change, etc.
After grinding out some of the tongue teeth, a dental veneer is applied to the tooth surface to keep the shape of the teeth as before.
In contrast, porcelain veneers are much lighter and lighter, and can be used to grind little or no teeth.
¡ú Appropriate tetracycline teeth, dental fluorosis, melon seed teeth and hereditary yellow teeth, melon seed teeth, tooth defects, teeth too small, etc.
¡ú duration resin veneer will be aging, need to be replaced after a few years;
Porcelain veneers should theoretically last ten years.
¡ú the advantage of porcelain veneer compared with resin veneer, color is good, shape is good, with real teeth almost no difference, its production process is very fine, not only can teeth whitening, but also the main method to treat tooth defects, dentition loss.
¡ú insufficient requirements for enamel are relatively high, if your enamel defect is greater 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.
