U1S1 Fan Ye is painted with bright lip color, and his sharp grin is the unforgettable impression of her Zui. There are also a variety of celebrity "looks out of the circle" photos, which is also the reason why grinning is the majority, casting a key reason for her group photo killer. Xiao Bian felt that it was inevitable that his teeth were white enough. As we all know, before becoming big white, Fan Ye also experienced an embarrassing period when his teeth turned yellow. In the entertainment industry, tooth correction and whitening are usually the first step of adjustment after entering the industry. One step shows how important a white tooth is to the appearance We ordinary people, wearing big yellow teeth and making up "easily dirty", are afraid to laugh even when taking selfies. Xiao Bian also saw that some people failed to give due to yellow teeth in the interview. It was really sad, but fortunately, there are still many ways to improve this matter. Let's talk today - what are the ways to whiten teeth? Is it harmful to teeth?
1、 What are the methods of tooth whitening?
#Cool light whitening
In the final analysis, cold light whitening is considered to be more widely used, and the actual effect is also better than X's "medical beauty" method. The method of cold light whitening can improve the five color levels~ultralow temperature cold light and prevent the harm to the dental pulp. More importantly, the cold light whitening operation basically does not touch the gums. The doctor will better maintain your gum sacs, and then proceed to the next step. It is because whitening toothpaste and dental instruments cannot protect Z drops.
In the whitening process, "pain" is inevitable. Because the doctor will design the treatment process of bleach and the hydrogen peroxide concentration value of bleach according to the condition of teeth and the category you can accept. Just like the hot maggie, the higher the kinetic energy, the more reasonable and painful.
#Whitening Toothpaste
The whitening toothpaste is also finished with hydrogen peroxide. This product is more obvious than tooth cleaning powder and can improve 2~4 colors. Are you excited? But I said that it does have many adverse reactions, such as "pain" in the application process. If you want to see it, you usually need 3 stickers to develop. If you want to feel sore, you will be persuaded to quit several times.
Once again, please don't stick it on the gums when using it, otherwise you will know what is true. The risk factor of reducing the product is also a problem. Crest toothpaste was brought back by the European Union because it added too much hydrogen peroxide. Therefore, the whitening toothpaste and the small side suggest first aid. It does not need more than two processes every year. People with tooth allergies should be more cautious.
#Weishang Dental Instrument
Don't buy a word. If the cosmetic brand is used as a dental instrument for medical machinery, it can not arouse vigilance. Teeth are aged and cracked, gums are atrophied and brittle, and injuries caused by tooth loss will be afraid of mud eruption! I didn't mean to frighten you. It was mainly the actual operation method of the home dental beauty instrument that decided that its risk reduction coefficient was worrying. Whitening agents can't stop the damage to the gums. Just like you change your acid skin and go to the hospital to brush, your face can still be repaired. However, if you abuse the tooth beauty instrument, your gums will shrink, and the damage is irreversible
Why brush your teeth every day or yellow?
Yellow teeth have both internal and external causes. The internal cause is the inherent tooth yellowness, tetracycline teeth or tooth yellowness caused by the growth of small teeth, which is more inconvenient. The tooth yellowness of most friends comes from external causes. Various colored foods in daily diet are the "additives" of teeth, which are likely to be stained, resulting in the teeth looking too dark.
It includes tea stain, coffee stain, cigarette stain, etc., as well as dark brown drinks such as Coca Cola, red wine, fruit juice, etc., which can also cause tooth staining. Therefore, friends who cannot grind coffee and tea without their hands are more likely to turn yellow. This adherence of melanin does not mean that every mouthwash can be cleaned.
Many melanins adhere to the teeth, which is difficult to clean without brushing, and the small gaps can not be taken care of at all. Moreover, most people can't brush their teeth immediately after meals, and they will be brushed if they come out for a long time. "Corrosive stain" can not be brushed off. Therefore, it is the key to brush teeth and prevent tooth yellowing at ordinary times, but the key role is to clean up food residues and prevent the "healthy" range of dental plaque, dental calculus. For the "whitening and cleaning" scope of the teeth that have turned yellow, it is simply handed over to the toothbrush for treatment. There is more than a little bit of effort but less effort.
Is tooth whitening harmful to teeth?
Today, due to the continuous upgrading and development of technology, everyone can reduce the risk of applying this technology, so tooth whitening does no harm to teeth. Generally speaking, cold light whitening tends to attack, and its fruit may last for 2-3 years. Once it is found that the color and luster of the teeth have decreased to a certain extent, the bright tooth whitening treatment can be carried out again.
Hao tooth whitening is to wipe non-toxic and harmless whitening materials on the surface of teeth, and then conduct one-time direct whole tooth irradiation. Therefore, it only takes about 30 minutes for Haoya to whiten teeth and remove the melanin accumulated on the surface and deep layer of teeth.
Tooth whitening is a way to reduce risks and whiten teeth reasonably. In the process of tooth whitening, it is not easy to contact the gums, so beauty seekers need not worry about the damage to teeth caused by cold light whitening.
Before tooth whitening, the doctor will check and evaluate first, and if there is no problem, you can start whitening. If there are dental calculus and dental plaque, it is better to soak and polish the teeth first to remove yellowing and whitening.
To sum up, there are many ways to whiten teeth, so you can choose your own method, but the premise is to choose a regular dental hospital to whiten teeth.
