Toothpaste is a special dosage form that has a therapeutic and prophylactic, hygienic, cleansing effect on the oral cavity. The paste contains all kinds of antimicrobial, bacteriostatic, abrasive, stimulating and surfactants.
After two days, using a special whitening paste, you can have white teeth. The most common advertising myth. Manufacturers fulfill their promise by adding abrasive substances to the paste. Thus, with the help of abrasive particles, we mechanically remove plaque. Dentists recommend buying only those toothpastes that have an RDA abrasive index. For people with sensitive teeth, you should use a paste with an abrasiveness index not higher than 75. If the toothpaste has an index of 200, then it can be used 1-2 times a week. Before using toothpastes containing special whitening oxidants, you should consult your doctor. It should be remembered that abrasive pastes, together with plaque, can damage tooth enamel, which can subsequently lead to staining and darkening of the deeper layers of tooth tissue.
Some toothpastes contain a unique ingredient, triclin, which helps restore teeth to their natural whiteness. Triclin (pentasodium triphosphate or just trisodium phosphate) is a substance that is used to clean tiles, bathtubs, and wash floors. It is part of many washing powders to soften water. When brushing your teeth, triclin can only reduce the acidity of saliva, thereby reducing the destruction of enamel. The mechanism of its action as a chemical bleach is not yet known to science.
The best toothpaste is sugar-free. According to the European Directive, any toothpaste must be free of sucrose and other easily fermentable carbohydrates.
Gelpastes are better than toothpastes. No, it’s not. In fact, gel pastes differ from ordinary ones only in that they are transparent. Just regular toothpaste contains calcium carbonate (chalk) and titanium dioxide, which give the paste its white color.
To avoid caries, all harmful microorganisms in the oral cavity must be destroyed. Triclosan or chlorhexidine (the most active anti-inflammatory and antibacterial agents), contained in antibacterial pastes, kill not only "bad" microbes, but also disrupt the natural microflora of the oral cavity. Triclosan was originally used as a cleaning agent in surgery. Possesses powerful antibacterial and antifungal properties. Well prevents plaque and gum inflammation. However, scientific research has found that triclosan triggers gene mutations in bacteria that learn to resist it over time. The bacteria, in turn, produce a protein that transfers the protective properties to other bacteria. This can reduce the effectiveness of antibiotics and other life-saving medications. Therefore, you cannot brush your teeth with such pastes for more than 2-4 weeks.
Toothpastes with honey additives are very beneficial for the teeth. This is just a publicity stunt. Honey in the subconscious of people is perceived (no need for a comma) as something useful. However, it should be remembered that this product is a favorable breeding ground for bacteria. In fact, various flavors and flavor enhancers are added to the "honey" toothpaste, creating the effect of the presence of honey.
Tooth powder is more effective than paste. Firstly, using a tube of paste is more hygienic. In a leaky box, toothpowder is susceptible to bacteria. Secondly, dental powders are abrasive and it is often not desirable to use them for people with sensitive teeth and gums, as well as for children.
Toothpaste should be chosen for the price. The more expensive, the more effective the paste. Not certainly in that way. Indeed, the more complex the paste is in composition, the more expensive it is. But the price also includes the cost of labor, the price of the packaging, the name of the manufacturing company. Domestic manufacturers, as a rule, offer a cheaper paste that is not inferior in quality and composition of raw materials to expensive foreign analogues.
Any toothpaste is suitable for a child. There are special therapeutic pastes for adults (from periodontal disease, whitening, with a high fluoride content) - they are not only not useful, but also dangerous for the child's teeth. Milk and recently erupted teeth, the enamel of which has not yet "got stronger", should be cleaned with a special baby paste. You can also swallow such pastes. Children are advised to first use helium, mildly abrasive, and then ordinary children's toothpastes.
Children need to brush their teeth with fluoride pastes to strengthen the enamel. The myth that fluoride is super-effective for the formation of tooth enamel appeared in the mid-twentieth century. Research into the effect of this substance on tooth enamel was funded in the 40s by American aluminum producers in order to solve the problem of disposing of toxic industrial waste. Then they convinced the US government of the effectiveness of adding fluoride to water and toothpastes. Later studies on caries prevention with fluoride did not support the myth. Fluoride, of course, is necessary for tooth enamel, but it is dosed, and its excess has a negative effect on the condition of the teeth. It is impossible to control fluoride intake with toothpaste, since, for example, children often swallow it when brushing their teeth. Fluoride can temporarily replace calcium and fill in the defects of tooth enamel. With prolonged use of chemically active synthetic fluoride compounds, there is a danger of displacing calcium from healthy parts of the tooth. This will cause a decrease in the strength of the teeth, since fluorine has a lower mineral density. Because of this, a disease such as fluorosis (increased fragility of the teeth) can form. According to experts, fluoridation causes more deaths from cancer than other chemicals, fluoride not only does not strengthen teeth, but it hardens arteries and the brain.
When you brush your teeth, there should be a lot of paste on the brush. The paste helps to freshen the oral cavity, cleanse food residues due to all possible additives. If you take a lot of paste, then it will foam too much, excess foam will only interfere with cleaning. In addition, excessive amounts of active ingredients contained in the paste can be harmful. The necessary and sufficient volume of toothpaste for cleaning teeth is about a pea, and for children - half as much.
The toothpaste needs to be changed. Yes it is. To avoid addiction, it is advisable to use two or more types of toothpaste. In addition, this will allow solving various dental problems - after all, there is no universal paste for all diseases. It is advisable to use a different paste in the daytime and evening.
