Milk Protects against Tooth Decay, New Study Finds

November 12, 2013 by Dr. Emanuel Layliev Blog


When imbibed after breakfast, a glass of milk a day may keep the dentist away.

A recent study found that the risk of tooth decay drops when milk is enjoyed just after breakfast. The decline is the result of decreased plaque acids, which milk may reduce by more than 50 percent!

Completed by the Department of Pediatric Dentistry at the University of Illinois, the study measured acid levels in the mouth after eating breakfast. It is these acids that are responsible for tooth decay and dental caries.

For the Study, 20 adult participants were asked to consume a bowl of the same cereal. They were then instructed to drink a glass of water, a glass of fruit juice, or a glass of milk.  While acid levels fell no matter what they drink, it was milk that was responsible for the largest decline. What does this tell us?

On a broader level, it is further evidence that what we eat and when we eat it has an impact on our oral health.  Whether enjoying full meals or small snacks, our teeth and gums are exposed to plaque acids each and every time we eat. One simple way to reduce these acids is to have a glass milk afterwards.
