At present, China is divided into ordinary toothpaste used in toothpaste, fluoride toothpaste and medicated toothpaste three categories. The main ingredients include ordinary toothpaste friction agents, cleansing agents, wetting agents, preservatives, fragrances, has a general role of toothpaste there, if dental health is better, you can choose ordinary toothpaste. However, with technological development, it was discovered that the fluoride could be the role of dental caries, and years of practice proved that fluoride in contact with the teeth, so teeth susceptible to acid dissolution of the organization in the formation of hydroxyl apatite fluoride is not soluble phosphorus Gray stone, thus enhancing the corrosion resistance of teeth. Studies have shown that commonly used this toothpaste, dental caries incidence reduced by 40% or so.

But to know that fluoride is a toxic substance, if the human body to absorb too much can cause fluoride poisoning, the state provides free fluoride toothpaste, fluoride should be between 400-1200Pm, with particular attention ,3-4 years ago, not suitable for children to use, because 1/8-1/4 of the toothpaste may be swallowed their stomach. Drug toothpaste is toothpaste on the basis of the ordinary plus certain medicines, toothpaste when brushing teeth reach the tooth surface or the surrounding environment, through the role of drugs, reduce plaque, which play the role of anti-caries and periodontal disease. At present, drug toothpaste highly favored people, but also to promote the use of toothpaste, a preventive effect or therapeutic efficacy of drugs is an ideal way.
