One: too much toothpaste can cause oral cancer .
There are several active ingredients in toothpaste that are worrying. The widely used chemical substance "sodium lauryl sulfate" in toothpaste is thought to cause gastrointestinal problems and liver poisoning, which can make the mouth more easily ulcerated and suffer from oral cancer. Abrasives in toothpaste are also believed to damage the gums and make the gums more susceptible, so do not squeeze too much when using toothpaste.
Second: improper use of fluoride toothpaste can lead to fluorosis .
Nowadays, fluoride toothpaste has been deeply rooted in the prevention of dental caries. To mention oral health care, the first thing that must be remembered is fluoride toothpaste. However, experts pointed out that although fluoride toothpaste can effectively prevent dental caries, it also has side effects. Improper use can lead to dental fluorosis. The boundary between the anti-caries effect of fluorine and the toxicity is very small. Ingestion of excessive fluoride teeth can cause spots, which is fluorosis, and the patients are mostly children. This is because children's swallowing control ability is not perfect, there are many opportunities to swallow fluoride toothpaste when brushing teeth, resulting in increased fluoride intake. Since toothpaste generally has no need to know, suitable for people and dosage, it causes a toothpaste to be shared by adults and children, and there is a phenomenon that the toothpaste is filled with a toothbrush like a TV commercial.
Experts remind consumers that it is best not to use more than 1 cm each time when using fluoride toothpaste. Children should not use fluoride toothpaste or use it carefully under the guidance of parents. At the same time, fluorine is a highly toxic substance. If the body absorbs too much, it will cause fluorosis. The free fluorine in the fluoride toothpaste should be between 400 and 1200Pm. It is important to note that children aged 3 to 4 years old should not use fluoride toothpaste because 1/8 to 1/4 of the toothpaste may be swallowed by them.
Three: Children should not use multi-foam toothpaste.
Children should not use multi-foam toothpaste. There are three types of toothpaste: multi-bubble, medium-bubble and less-foam. The amount of foam depends on the amount of soap. The multi-bubble toothpaste has a high soap content and is easy to irritate the oral mucosa in the oral cavity.
Four: The use of a single toothpaste in the morning and evening is not good for oral health.
Oral experts have suggested that toothpaste products should be used interchangeably with changes in seasons and physical conditions. Do not always use products of the same brand or the same function. In advanced countries in Europe and America, more than 80% of consumers have separated toothpaste for morning and evening, and they have the habit of regularly checking their teeth. Studies have shown that most of the oral problems are caused by bacteria, and the saliva secreted by the human mouth has a bactericidal function; however, the amount of saliva secreted during the day is 3-4 times that of the night, which is easy to inhibit the production of bacteria; when the person is in a sleep state, the salivary gland Insufficient secretion, dry mouth, can lead to acidification of the mouth, can not inhibit the proliferation of bacteria, causing various oral problems.
Five: Drug toothpaste should not be used for a long time.
At present, many kinds of toothpastes such as desensitization, anti-inflammatory and tooth-protecting, deodorizing and hemostasis have emerged. The advertising campaign is overwhelming. Many people use the drug toothpaste as a panacea for oral diseases. Whether or not there is dental disease, the drug toothpaste is used. This is not appropriate. The bacteria in the mouth are divided into pathogenic bacteria and non-pathogenic bacteria. They restrict each other and maintain an "ecological balance" in the mouth.
Long-term use of a strong bactericidal drug toothpaste will not only make the pathogenic bacteria in the mouth resistant, but also inhibit and kill the pathogenic bacteria, but also inhibit and kill the normal flora in the mouth, so that the oral cavity The “ecological balance†has been destroyed, causing new oral diseases and new infections. In addition, some medicine toothpastes contain alkaloids and irritating substances. Long-term use not only damages the delicate mucous membranes in the mouth, but also causes inflammation of the gums, mouth, tongue, etc. due to long-term stimulation, causing gingivitis and oral cavity. Inflammation, glossitis, etc.; people with allergic asthma cough will have cough and gastrointestinal discomfort due to the irritating odor of the drug toothpaste. Some drug toothpastes also contain gluconin, which will contaminate the tooth surface and cause the tooth to lose its luster. Beautiful teeth.
For people with oral diseases, it is best to use fluoride toothpaste and drug toothpaste instead. For middle-aged and elderly patients with both dental caries and periodontal disease, it is better to choose fluoride and Chinese herbal medicine products in the morning and evening. . For patients who are sensitive to cold and heat, it is best to use anti-acid products that are resistant to dentin hypersensitivity in combination with general fluorine-containing products.
