Singapore: A new research study conducted by the Academy of General Dentistry, US, has found that eating cheese increases production of alkaline saliva, in turn preventing you from problems related to tooth decay.
The study that was first published in the journal General Dentistry, divided 68 children aged between 12 and 15 into three groups. While one group was asked to consume a daily portion of cheddar, the other group consumed a sugar-free yoghurt. The third group consumed a glass of milk, followed by a mouth rinse.
The pH levels on the dental plaque of all these three groups were measured before and after the test and between ten minute gaps. "We found that those who ate the yoghurt or drank the milk showed no changes to the pH levels in their mouths at any of the intervals," said Dr Vipul Yadav, lead researcher.
The core findings of the study were that chewing cheese created a protective layer around teeth which kept remaining acid at bay. Further, it found that cheese helps reduce cavities forming in teeth because it neutralises plaque acid.
Those who ate the cheese showed a rapid increase in pH level at each of the time intervals. Further, cheese releases chemical compounds that can form a protective layer on teeth which further protects it against the acids that attack enamel.
"The groups who consumed milk and sugar-free yogurt experienced no changes in the pH levels in their mouths. Subjects who ate cheese, however, showed a rapid increase in pH levels at each time interval, suggesting that cheese has anti-cavity properties," the research spokesperson said.
The study concluded that the higher the pH level on the surface of teeth, the more teeth are protected against dental erosion, which causes cavities and leads to fillings.
