How to choose toothpaste
Toothpaste that is used every day, but there may be hidden dangers?
According to a report by People’s Daily on May 2, the articles reprinted on the official website of the General Administration of Quality Supervision, Inspection, and Quarantine suggested that six brands of whitening toothpaste, China, Colgate, Black Girl, Crest, Black, and Libai, were coated with bleach sulfite andAnalogs, long-term use has hidden health hazards.
This news is enough to make whitening toothpaste begin to be questioned, and the safety of other functional toothpastes has also attracted much attention.
What kind of toothpaste is better, how to use it is safer and more effective?
“Life Times” reporter consulted relevant experts.
It is understood that sulfite and its analogs are generally used in the papermaking and other industrial fields, and it is a substance that is explicitly forbidden in the mandatory national standard GB22115-2008 “Specifications for Raw Materials for Toothpaste”.
However, in the routine testing of toothpaste, there is no requirement for sulfite, so it is “difficult to say” whether toothpaste on the market contains sulfite.
The China Oral Cleansing Products Industry Association issued a statement saying, “According to the experimental details described in the relevant report, the method for testing the whitening ingredients in whitening toothpaste is scientifically uncertain.”
And what is the result of this incident, in the opinion of Professor Bi Liangjia, a member of the Periodontology Group of the Chinese Stomatological Association, any whitening toothpaste has little effect.
There are only two methods for whitening teeth, namely removing the stains on the teeth and improving the brightness of the teeth.
The former needs to go to the hospital for treatment, and usually requires the use of whitening agents to oxidize and dissolve tooth stains.
Although the bleach in whitening toothpaste can remove some stains on the tooth surface, it has basically no effect on the deep internal stains of the teeth. This is some consumers “even after brushing for three or four months, the tooth color has not changed”White.”
Moreover, because the whiteness of teeth is related to enamel and dentin, the structure of Chinese teeth has determined that our teeth are white and yellow, which cannot be changed by expensive whitening toothpaste.
Experts said that in addition to over-whitening toothpaste, there are still many misunderstandings in the process of using toothpaste.
To clean your teeth more effectively, it’s best to follow these points when choosing toothpaste.
Most people choose fluoride toothpaste.
Ouyang Yong, deputy director of the department of oral prevention at Guanghua Stomatological Hospital of Sun Yat-sen University, said that currently the fluoride toothpastes currently used generally account for about 70% of the entire toothpaste market.
Consumers in high-fluoride areas do not need to use fluoride toothpaste, but the water fluorine concentration has decreased in many cities. It is still necessary to promote the use of fluoride toothpaste in these areas.
American dental health experts also agree that the general population is best to choose fluoride toothpaste.
Tests show that brushing your teeth twice a day with fluoride toothpaste reduces the risk of dental caries by 40%.
However, Wang Weijian, director of the Prevention Department of Peking University Stomatological Hospital, reminded that adolescents and the elderly can be used more. Preschool children should be used with caution and parents need help to avoid accidentally swallowing toothpaste. In the long run, it may cause excessive fluoride intake and the potential for fluoride poisoning.Threat.
Use toothpaste with caution.
The Beijing Consumers Association issued a consumer warning. Consumers without oral diseases and dental caries should not blindly choose functional toothpaste.
Once selected incorrectly, anonymity may occur.
Chinese herbal toothpaste can reduce inflammation and reduce fire, and it has certain effects on periodontal health. However, long-term bleeding of gums must go to the hospital for treatment. Do not expect toothpaste to correct the healing effect. Anti-allergic toothpaste can relieve sensitive teeth, but the cleaning effect is not as good as ordinary toothpaste.Moreover, American studies have found that triclosan contained in some toothpastes may interfere with the human immune system and be used continuously for a long period of time; the long-term use of the pharmaceutical ingredients in drug toothpastes may cause imbalance in the oral flora, and some drugs mayEnter plasma; long-term use of calcium-containing toothpaste may increase the concentration of calcium ions in the oral cavity, and promote the formation of calculus; salty toothpaste should be used with caution in patients with hypertension and so on.
Prevent damage, pick small particles.
Ding Xiaoyi, deputy secretary-general of the Chinese Stomatological Association, said that when buying toothpaste, the quality of the friction agent depends on the quality of the friction agent.
Aluminium hydroxide and calcium hydrogen phosphate are better, followed by silicon dioxide, and calcium carbonate is the lowest.
In addition, the particles of various friction agents are all different in size, and the finer the particles, the less damage to the tooth surface.
Buy two, use them sooner or later.
It is understood that in advanced countries in Europe and the United States, more than 80% of people will use toothpaste with different functions in the morning and evening to better protect their teeth.
Professor Bi Liangjia said that the saliva secreted by the human oral cavity has a bactericidal function. During the day, the saliva secretion is 3 to 4 times that at night, which is easy to inhibit the production of bacteria. In addition, it eats more during the day, and it is easy to leave food residues in the mouth. Therefore, the cleaning function should be replaced.Good, toothpaste that can eliminate foreign bodies and odors; at night, when people are sleeping, the salivary glands are insufficiently secreted. Tooth decay should be used to prevent dental caries.
Toothpaste squeezes the size of soybeans.
Many people are affected by advertisements. When squeezing toothpaste, they like to squeeze a whole stick on the toothbrush. If swallowed by mistake, it will accumulate over time and cause fluorine replacement.
Fluoride is one of the essential elements in the human body. The fluoride in the human body will suffer from dental caries, but too much fluoride in the body will also form fluoride plaque and make the teeth brittle.
Toothpaste does not dip in water for good results.
Most people habitually wet their toothbrushes before squeezing toothpaste.
Experts believe that it is not advisable to moisten the toothbrush before brushing it, because it will easily foam, and people will mistakenly think that the tooth has been cleaned.Toothpaste is not originally used to clean teeth with foam, but by the cleaning ingredients and friction between the toothbrush and the teeth.
The finer the friction and the longer the time, the cleaner it will be.
