Remineralizing your teeth is easier than you might think
The enamel on our teeth is made out of calcium phosphate, which
are minerals. When you eat or drink flavored beverages, the bacteria in our
mouths metabolize what been consumed and makes acids. These acids demineralize
the teeth by removing minerals on the enamel.
In order to remineralize the enamel on our teeth and help
protect it from cavities, we really need to do one thing: spit. The minerals in
your saliva will allow that remineralization to happen. Saliva has calcium and
phosphate in it and some other buffers that will help buffer that acidic state.
If our mouths produce saliva, then why do we get cavities at
all? The answer, in part, is due to the way—and frequency— in which we eat and
drink. If while sitting at our desks, we nurse a couple cups of iced-coffee all
day, never giving our mouths the chance to return to that neutral state, then
we leave our mouths freaking out on acid, so to speak— an intense state that
compromises tooth health.
It takes a little over a half hour for your mouth to go from an
acidic state after eating or drinking a flavored beverage, to a neutral state,
in which the saliva can exercise its healing power. If you’re sipping coffee,
and you take another sip, then you’re starting at square one again. And this
all-day exposure to acidic foods or drink is what leads to cavities.
Optimally, we should take a two-hour break after eating a meal
or finishing a drink in order to allow our saliva to remineralize teeth. If you
want to accelerate your mouth’s healing time, the American Dental Association points to
studies that show using
Xylitol gum or mints (Spry) after meals can lower instances of tooth decay, by
increasing saliva flow.
While our bodies are self-equipped to remineralize teeth, this
biological auto-correct isn’t enough to ward off tooth decay and cavities on
its own. Maintaining proper dental hygiene, including flossing once a day and
brushing twice a day for two-minutes increments is vital.
Bottom line:
keep your mouth off acid between meals, take some time with brushing and your
teeth will find their way back to their mineral-hardened state—no hand-churned
toothpaste or high-maintenance diets required.
