A new study from Norway shows that keeping your teeth brushed properly and maintaining oral hygiene can not only prevent tooth decay, help maintain good chewing and gastrointestinal function, but also prevent the development of dementia.
Gingivitis (gingivitis) is a common oral disease in the elderly and is caused by porphyromonas gingivalis.
Peter medel and his team, from the research laboratory of the department of clinical sciences at the university of bergen in Norway, demonstrated that porphyromonas gingivalis can be transferred from the mouth to the brain.
Harmful enzymes produced by porphyromonas gingivalis damage nerve cells in the brain, causing memory loss in the elderly and eventually leading to anorexia.
The team observed and detected the harmful enzyme in 96 percent of 53 patients.
Dr. Medale cautions that porphyromonas gingivalis does not cause aging alone, but the presence of the bacteria can greatly increase the risk and cause the disease to develop more quickly.
"Brush your teeth well and floss," he advises.
"The primary purpose of brushing is to remove plaque, which forms a stable attachment to the surface of the tooth.
Dental calculus, tartar these unclean substances can only stay on the surface of the tooth through the dental plaque, and then cause tooth inflammation, bleeding and even loose tooth loss.<-->纽约时报中英文网 http://www.qqenglish.com<-->
About 30 minutes to 60 minutes after the meal, dental plaque can form a stable adhesion on the tooth surface, therefore, it is recommended to brush within 15 minutes to 30 minutes after the meal the best effect, can effectively prevent the formation of dental plaque, there will be no calculus, tartar.
Most people life is only a pair of permanent teeth, dental caries is slowly, the teeth can't be repair regeneration after injury, so should be at an early age to develop good habits of brushing tooth right, and should always observe the teeth (especially the back a few teeth caries) easily caries turning black, and so on and so forth, if you have to handle in time, or caries slowly will be worse, even need fillings and tooth extraction.
In addition, we can have a dental cleaning every two or three years, which is conducive to washing away the calculus that cannot be removed by brushing, reducing periodontitis and delaying the deposition of dental plaque.
