Remember when we were told to drink milk as children to keep our teeth strong? Well, scientists have found that its “relative” – regular kefir – may be an even better protector of your smile.
The mouth is a big city, home to a variety of microbes: some are good “residents” and some are “hooligans.” The main hooligan that causes cavities is called Streptococcus mutans. This bacteria loves the sugar you eat. It digests it and releases acid, which, like a drill, makes holes in your teeth. That's how cavities appear.
How does kefir help you get in shape?
Kefir is not just sour milk. It's a whole army of beneficial bacteria (probiotics) and yeast that work like real superheroes for your teeth. Here's how they fight “evil”:
Take up space. The good bacteria from kefir settle in your mouth and take up all the “comfortable places.” The hooligans Streptococcus mutans simply have nowhere to attach themselves.
They organize “hunger games.” Kefir bacteria eat up the nutrients that harmful microbes need to reproduce. No food, no bullies.
They produce their own “weapons.” They secrete substances (such as organic acids) that harmful bacteria don't like and prevent them from living.
As a result, there are fewer bad guys, less plaque is formed, and the risk of cavities and gingivitis is reduced. A study published in the Dentistry Journal showed that the effect of kefir was similar to the effect of a fluoride rinse!
But don't rush to throw away your toothbrush!
This all sounds cool, but there are a few “buts”:
The science is still in its infancy. Most studies have been small and short. Scientists have used different types of kefir and different doses (some drank half a glass, some a whole glass). So there is no single recipe yet.
Kefir is an aid, not a cure. It will not replace the main rules of dental care: brushing twice a day, flossing, using fluoride toothpaste, and, of course, visiting the dentist. Kefir is simply a useful bonus to daily care.
Important point: kefir is a “live” product. If a person has serious immune problems, they should consult a doctor before relying on any probiotics.
What's the result?
Adding a glass of kefir to your diet is a great idea. It can be your little secret ally in the fight for a healthy and beautiful smile. Just remember that it works as a team with your toothbrush and dentist.
