Is the cold light tooth beauty instrument harmful to teeth? 1 The cold light whitening instrument itself has no harm to teeth, mainly because it emits a cold light, which will accelerate the working efficiency of hydrogen peroxide by 30% when it acts on the surface of teeth. The acidity of 30% hydrogen peroxide is still relatively high, which will cause some damage to the tooth surface, but after scientific research, the damage will basically repair itself in about 1 week. Therefore, there will be a brief dentin allergy after cold light whitening. Generally, the teeth will be remineralized and become very strong around 1 week, so patients can normally perform cold light whitening without other concerns.

Is the tooth beauty instrument harmful to gums?

Cold light tooth whitening instrument is a cold light whitening technology introduced from the United States. This technology can not only remove the tartar and calculus in teeth, but also remove the pigment deposition on the surface of teeth. At the same time, cold light whitening can also enter the deep layer of teeth to achieve the effect of decoloration and whitening.

However, the most serious risk of long-term use of dental beauty instrument is gingival atrophy, which seems to have no way to recover. However, all dental instruments on the market contain hydrogen peroxide and compounds containing hydrogen peroxide.

However, hydrogen peroxide is highly irritating and easily causes toothache and allergies. At present, the US Food and Drug Administration has banned the sale of oral products containing hydrogen peroxide in the market from 20 17.

However, many WeChat merchants will introduce their own tooth beauty instrument, which is very healthy and is the most effective and safest tooth whitening technology at present. In the process of whitening teeth with hydrophilic drugs, it does not touch gums at all, and will not cause any harm to tooth structure and enamel. In this case, let's weigh ourselves.

Can cold light whitening lead to tooth loss?

Cold light whitening is high-intensity blue light, which is transmitted through optical fiber to whiten teeth. It can not only remove the pigment deposition on the surface of teeth, but also enter the deep layer of teeth to achieve the effect of decoloration.

Core Tip: Cold light tooth whitening is believed to be familiar to everyone, which can make yellow teeth whiten quickly. Now all kinds of cold light tooth whitening instruments have appeared in the omnipotent circle of friends and Taobao, claiming to whiten teeth without going to the clinic. In fact, this cold-light tooth whitening instrument is not reliable. Not only is there no medical device approval, but blind use is also easy to damage tooth health.

White teeth are the key to a charming smile. If the teeth are yellow and black, it will especially affect the image. In the past, everyone went directly to the dental clinic to whiten their teeth. Nowadays, the cold light tooth whitening instrument, which is wildly circulated in friends circle, is quite popular. It is said that you don't have to go to the hospital to whiten your teeth anymore. Is it useful? Many people have such questions. Let's learn more with me.

Dental experts say that there is still a big gap between the cold-light tooth whitening instrument sold online and that used in stomatological hospitals. When oral patients go to the hospital for cold light whitening, they will apply protective paint on their gums and then apply whitening agent. The reason for this is to avoid the harm of whitening agent to gums.

The cold light whitening instrument in the circle of friends has only whitening agent and no protective coating. The second kind of cold light whitening is to irradiate the whitening agent with high-intensity blue light to oxidize it, so as to achieve the whitening effect, because blue light will hurt the eyes and wear goggles when doing it. The cold light whitening instrument in the circle of friends can work as long as a few batteries are installed. Obviously, the intensity is not enough to irradiate blue light, and the whitening agent applied may actually be an acidic exfoliating component. Long-term use of this acidic exfoliating ingredient will lead to enamel damage and teeth becoming more and more sensitive.

Whether the cold light tooth whitening instrument is useful again depends on whether the instrument has passed the inspection standards of health institutions, whether there is approval for medical devices or drugs, whether it is toxic to human body, and whether it will cause damage to the hard tissue and pulp of teeth. At the same time, beauty lovers should also understand that cold light tooth whitening is not suitable for everyone. Professional doctors will check the condition of teeth for beauty lovers before cold light whitening. If the tooth has periodontal disease, it must be repaired before cold light whitening can be done. Blindly whitening teeth is not advisable.

In summary, the cold light tooth whitening instrument in the circle of friends is useless. If you want to do cold light whitening, it is recommended to choose a professional and regular dental hospital to whiten your teeth scientifically and make yourself more at ease. Blindly buying a whitening instrument not only costs money, but also threatens your dental health.

Brush your teeth first, then squeeze the whitening agent on the denture base, and finally put the denture base on your teeth, and the cold light irradiation will be over. Is this a simple version of cold light whitening?

Let's look at the ingredients of those dental instruments again.

The main component of these dental instruments is also hydrogen peroxide, the content of which does not exceed 6%. Generally, the content of hydrogen peroxide in the gel used in stomatological hospitals is 40%, so a protective agent will be coated on the gums. However, none of these household dental beauty instruments are equipped with gingival isolation agent, and the gel is directly coated on the denture base and then worn on the teeth. The denture base may not be completely attached to the tooth veneer. When the condensate on the denture base contacts the teeth, the condensate may contact the gums, causing gum damage.

Without professional operation, these dental instruments will also bring the following injuries: damage to the tooth surface, which will not only cause scratches on the tooth surface, but also make the teeth lose smoothness; In the process of whitening, it will cause harm to teeth. If there are porcelain teeth, it may also cause porcelain collapse, discoloration of restorations, gingivitis and other symptoms.
