Why do you have to change toothpaste

Because toothpaste has different ingredients, its functions are also different. The Popular Health Network reminds you that when choosing toothpaste, you must "prescribe the right medicine" according to your personal needs.

Anti-inflammatory:

Adding certain antibacterial drugs to ordinary toothpaste has anti-inflammatory and antibacterial effects, but long-term use can easily lead to an imbalance of normal oral flora. Therefore, it is best to replace toothpaste with other functions after using up a tube.

Hypoallergenic category:

Adding desensitizing ingredients such as fluoride and strontium chloride to toothpaste can only relieve mild dentin allergy to a certain extent. If it is still ineffective after a period of time, it should be stopped.

Desensitization and acid resistance:

This toothpaste can form a protective film on the tooth surface, reduce the permeability of tooth hard tissue, improve the buffering effect of tooth tissue, and thus increase the disease prevention ability of periodontal tissue. It should be noted that you should stop using this type of toothpaste after the symptoms improve, otherwise it will destroy the microbial ecological balance in the mouth and cause other diseases.

Whitening category:

This type of toothpaste contains drugs such as peroxide or hydroxyapatite, which remove discoloration on the surface of teeth through friction and chemical bleaching, thereby whitening teeth. However, if the abrasive particles in the toothpaste are large and hard, long-term use may cause tooth wear.

The Popular Health Network specifically reminds you that it is best to use toothpastes with different functions alternately to avoid tolerance due to long-term use of a certain type of toothpaste, which would greatly reduce its effectiveness.

Should I use fluoride toothpaste?

Fluoride toothpaste to prevent and treat tooth decay

The newly implemented national toothpaste standard has detailed regulations on the fluoride content of toothpaste. This is because fluoride is one of the components of tooth structure. An appropriate amount of fluoride can make tooth texture smooth, hard, acid-resistant and wear-resistant, thereby effectively preventing and treating tooth decay. However, if the fluoride content is too high or too low, it may damage the strength of the teeth. To prevent and treat tooth decay, using fluoride toothpaste is a good way.

Children should be careful when using fluoride toothpaste

Children tend to swallow toothpaste while brushing their teeth. Although there have been no reports of fluoride poisoning in children, ingestion of fluoride toothpaste can cause certain harm to children's bodies and teeth. Children aged 4 to 6 should use toothpaste under the guidance of their parents, and the amount used each time is generally the size of a soybean. After the age of 25, people's teeth undergo remineralization, which increases their resistance to caries. The incidence of caries decreases significantly and tends to stabilize. At this time, there is no need to choose fluoride toothpaste.

Toothpaste cannot supplement calcium

Currently, the common toothpastes on the market, if classified by their effects, mainly include whitening toothpaste, medicated health toothpaste, anti-caries toothpaste and ordinary toothpaste. Regardless of the type of toothpaste, its main ingredients are generally abrasives, foaming agents, lubricants, flavorings and some other added ingredients. Toothpaste does not stay in the mouth for long and is quickly spit out. Some toothpastes that are said to have "special functions" have "special ingredients" that are difficult to exert their medicinal effects in a short period of time. For example, the calcium that has been corroded by acid on the teeth is difficult to replenish through calcium supplements, and adding "calcium" toothpaste cannot replenish calcium for the teeth at all.
