Therefore, cosmetic dentistry has become a fashion that everyone yearns for in modern society.
However, at present popular very hot all kinds of tooth whitening methods, whitening at the same time, will bring to your teeth what kind of damage?
What do you know about the side effects on dental health?
How can you make your teeth look better without sacrificing their health?
Let’s learn it together!
First, what kind of teeth need whitening?
Just like the trials of life, teeth will also undergo various “tribulations” during the course of life, leading to the yellows of originally white teeth.
First of all, during the development of teeth, due to poor nutrition or poor bone development, teeth will be affected by the calcification of teeth, so that teeth become yellow and brittle from an early age.
Secondly, in the process of tooth development, they face the dangers of drugs or drinking water, typically is due to the mother or child taking tetracycline tetracycline teeth, as well as the long-term high fluoride drinking water containing high fluoride water source area of fluorine spot tooth, in childhood will be white teeth become yellow, become the main endogenous of yellowing teeth harm;
Finally, because the teeth surface exist a variety of bacteria, these bacteria all the time in the secretion of many sticky substance, and people in their daily such as tea, coffee, eating habits such as smoking, will leave pigment on the teeth, the pigment is easy to be adsorbed on the bacteria secrete sticky material, make the surface yellow or black teeth.
If not cleaned in time, these substances will gradually invade the inside of the tooth from the surface over time, forming internal stains and causing the inside of the tooth to turn yellow. This kind of exogenous harm from the dietary process is a lifelong threat to the health of teeth.
The yellowing of teeth caused by these factors has become a problem for people, and they all need whitening.
Second, at present the most “fire” teeth whitening method compares advantages and disadvantages, and note that we have found that because of the relation of interests, teeth whitening ads often will only tell patients the whitening effect, and not with patients that adopted by means of teeth whitening may lead to many side effects, in order to let everybody can identify by spectrum whitening products or methods,
In this paper, we will comprehensively reveal for the first time the “deficiencies” hidden in the most popular tooth whitening methods: 1. The best cosmetic restoration method is porcelain teeth, especially for the cases of tooth defects, which is also the oral restoration with the best density and the color effect closest to the natural color.
Because bacteria cannot live on the surface of porcelain teeth, they do not have cavities in addition to whitening effects.
Suitable for people: Suitable for moderate and severe tetracycline teeth, dental fluorosis, enamel hypoplasia, teeth crack, incomplete, hole serious cases, whitening effect is obvious.
Duration: In theory, if your gums stay healthy (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.
Disadvantages: To make porcelain teeth, the original teeth must be ground down. The damage to the teeth is irreversible. Teeth that are ground into a rod are very fragile, and there is a high possibility of sequelae such as gingivitis, periodontitis and gingival atrophy after a period of time.
2, cold light whitening this is known as a fast and safe tooth whitening technology.
Low temperature cold light to avoid the treatment of dental nerve stimulation.
The main ingredient of whitening agent is hydrogen peroxide, disposable and non-irritating.
The advantage is that the procedure is very simple: apply a layer of protective agent to the gum edge, apply whitening agent to the tooth surface, shine a cold light whitening lamp (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 population: exogenous pigment teeth (coffee, tea stains, smoke stains deposition), moderate and mild tetracycline teeth, drug discoloration teeth and genetic yellow teeth.
Duration: About 2 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.
Cons: Cold light whitening is done by shining cold light on the teeth to coat them with a gel, which can discolor the teeth.
So, cold light whitening actually is still by bleaching drugs to the principle of teeth whitening, so-called cold light just improve prescription decoloring rate auxiliary tool, usually in the operating process of teeth feels very ache, it is because of bleach has damage to the teeth enamel, finish dentin allergies (hot and cold response) and even teeth embrittlement risk is very big,
And cold whitening teeth are a little scary in the dark under fluorescent lights.
3. Veneer whitening veneer whitening is to stick a layer of veneer on the tooth surface, which plays a role in shielding the discolored teeth.
Now popular dental veneer can be divided into resin veneer and porcelain veneer two kinds.
Resin veneers are applied to the surface of a tooth after part of the tooth has been ground away, which can keep the shape of the tooth as before.
And porcelain cover is brings together the advantages of porcelain teeth and resin overlay, more beautiful and vivid, it is said that this is the computer ultra-precision sculpture cutting equipment and technology, will be similar to tooth enamel of the whitening strips with teeth cut into the shape of a completely closed, with special active interface material will closely Mosaic tiles on the teeth, so the price is more expensive,
And it lasts longer than the resin.
Suitable population: tetracycline teeth, drug discoloration teeth and hereditary yellow teeth.
Duration: theoretically up to a dozen years.
Advantages: Compared with resin veneer, porcelain veneer has good color and shape, almost no difference with real teeth, and its production technology is very fine, which is the main method to treat tooth defects and dentition loss.
Shortcomings: Although the teeth will immediately become white after veneer, it is also very natural and realistic, but it will be easy to fall off, easy to change color, and easy to cause gum swelling, bleeding inflammation and other sequelae;
Resin veneer has a certain thickness, will make the lip slightly convex, beautiful appearance has a certain impact, and the price is not cheap.
4, tooth bleaching bleaching, is to order a transparent dental tray, every night the liquid squeezed on the dental tray, wearing the dental tray to sleep.
Bleaching can be divided into “outer” and “inner” two kinds: external bleaching is suitable for moderate non-defect dental fluorosis and tetracycline tooth decolorization treatment, 3-5 weeks can achieve satisfactory results.
Drift in atractylodes: mainly used in anterior tooth discoloration, no dental pulp or serious tetracycline tooth discoloration of repair, method is to do routine root canal treatment first, then dip in with a small cotton ball with 30% hydrogen peroxide into medullary cavity, with zinc oxide clove oil cement tightly closed, 2 ~ 3 days change medicine, 4 ~ 7 times can receive good effect, the final hole with composite resin filling.
This method is more damaging to the teeth and very painful.
Suitable crowd: Apply to slight pigmented tooth development is not complete, the tooth color that changes because of AGE growth enamel is yellow.
Duration: 2 to 3 years.
Advantage: Relatively cheap price.
Shortcomings: the color of tetracycline teeth, dental fluorosis and other effects are poor, because only the surface whitening, not durable, but easy to cause tooth sensitivity.
And need to pay attention to: bleaching is not effective for everyone, the color of tetracycline teeth, dental fluorosis and other effects are poor, because it can only make the tooth surface white, not durable, and because of the damage to the tooth enamel bleach, easy to cause tooth sensitivity.
5. Dental cleaning refers to the removal of calculus and plaque on the surface of teeth by doctors with ultrasonic dental cleaning machine and sandblasting dental cleaning machine, and the washing of stones and calcified dirt on the surface of teeth.
Tooth cleaning is completely different from ordinary brushing. It can not only clean the superficial surface dirt of teeth, but also completely remove the plaque, stones and pigment that can not be removed by brushing. When cleaning teeth, it is easy to find small and imperceptible dental diseases, such as relatively hidden dental caries, to achieve the purpose of early detection and early treatment.
Pertinence: It can remove the pollutants on the tooth surface, and has a good effect on mild tooth discoloration.
Duration: six months.
Advantages: Whitening teeth and maintaining periodontal health.
Deficiency: Only surface white, rather than whitening.
After cleaning, a small number of people will produce teeth to cold and hot have more sensitive acid and soft phenomenon.
Frequent tooth cleaning will cause loss and damage to the enamel on the tooth surface.
Three, re-examine the necessity of tooth whitening and the consequences that may be caused, it is important to recognize the misunderstanding is beautiful, health or to put in the first place, want to achieve the dual purpose of health, beauty, as far as possible to choose regular dental hospital.
After careful consultation and careful consideration, the choice is made to ensure satisfactory cosmetic results and long-term dental health.
