Often drinking bottled water is easy to tooth decay

Australia's Oral Health Research Center, researchers found during the survey research: an increase of 71% of 14-15 year-old child suffering from permanent tooth decay within the next six years. The researchers clearly pointed out: This is a great relationship with the popularity of the 1990s, bottled water and sports drinks.
 The reason is that, in the ordinary bottled water, not only calcium, phosphorus and other minerals with little or zero, but the lack of reinforcement of tooth enamel (ie enamel - covering the tooth outermost translucent calcified tissue) the role of fluorine compounds, resulting in greatly increased the risk of children suffering from tooth decay. This is because the calcium, phosphorus and other minerals and fluoride is important in promoting the growth of teeth and protect the dental health. Calcium and phosphorus are the main raw material of the teeth constitute about 99% calcium in the body is concentrated in the bones and teeth, whether infant or young people, if the calcium can not meet the need, or intake of calcium in the body for various reasons can not be the body absorption and utilization, will affect the teeth strong.
 Teeth due to calcium deficiency will become loose, easy corrosion generated dental caries by oral bacteria. Fluoride in the fluorine can penetrate into the enamel of the tooth surface, forming a fluorescent phosphorus gray matter, acid resistance, and thus play a role in strengthening teeth, fight bacteria, and protection of oral.
 Human tissues contain fluorine, but mainly accumulate in the teeth and bones. This has been confirmed in epidemiological investigation: increased risk of dental caries rate countries, the prevalence of enamel hypoplasia was also higher.
 Found that many countries in the tap water the right amount of fluoride to let people drink at the same time can make the teeth to the appropriate protection. Of course, the water fluoride content is too high is not good, otherwise it will cause dental fluorosis, the same unfavorable dental health. China's regulations in drinking water fluoride concentration is less than 1.0 mg / l.
 The experts pointed out, calcium, fluoride and other essential minerals and trace elements, one of the water body for these substances. Special circumstances under the conditions of the main sources. Therefore, experts recommend that parents usually best to limit the children too much to drink bottled water, tap water-based.
 Schools should be to create conditions to allow students to drink clean boiled water to facilitate their related essential minerals intake from drinking water, such as trace elements, to ensure that the dental and physical health.
