Cutting the Cheese is Good for Our Teeth…

Some cheeses emit a less than delectable odor, but did you have any idea that cheese is actually one food that is good for the health of our teeth and gums?
New research from the Academy of General Dentistry highlights how consuming cheese and other dairy products may help protect teeth against cavities.
Is Cutting the Cheese Good for Our Teeth?
The study, published the May/June 2013 issue of General Dentistry, the peer-reviewed clinical journal of the Academy of General Dentistry (AGD), sampled 68 subjects ranging in age from 12 to 15, and the authors looked at the dental plaque pH in the subjects’ mouths before and after they consumed cheese, milk, or sugar-free yogurt.
A pH level lower than 5.5 puts a person at risk for tooth erosion, which is a process that wears away the enamel (or protective outside layer) of teeth.
“The higher the pH level is above 5.5, the lower the chance of developing cavities,” explains Vipul Yadav, MDS, lead author of the study.
The subjects were assigned into groups randomly. Researchers instructed the first group to eat cheddar cheese, the second group to drink milk, and the third group to eat sugar-free yogurt.
Each group consumed their product for three minutes and then swished with water. Researchers measured the pH level of each subject’s mouth at 10, 20, and 30 minutes after consumption.
Eating More Cheese, Equals Less Cavities?
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 study indicated that the rising pH levels from eating cheese may have occurred due to increased saliva production (the mouth’s natural way to maintain a baseline acidity level), which could be caused by the action of chewing. Additionally, various compounds found in cheese may adhere to tooth enamel and help further protect teeth from acid.
“It looks like dairy does the mouth good,” says AGD spokesperson Seung-Hee Rhee, DDS, FAGD. “Not only are dairy products a healthy alternative to carb- or sugar-filled snacks, they also may be considered as a preventive measure against cavities.”
So the next time someone cuts the cheese around you, make sure you grab a slice to protect your chompers!
