Coffee stains reveal bone-healthy benefit for teeth

Coffee has come a long way. A daily cup of coffee used to be a guilty pleasure. Now it’s a healthy habit. Research shows it helps your brain, liver and heart, among other body parts.

But what about your teeth?

Most people will tell you coffee isn’t good for your teeth. It’s acidic and turns them brown. But most people are wrong…

Well, not entirely. Coffee is acidic. And it does dull your smile. But it helps your teeth in another way…

Peak D3

When you step out into the sunlight, your body begins the process of making vitamin D. But getting the ideal amount can be difficult because some of us can’t effectively absorb it. That’s just one of many reasons the vitamin D deficiency is an epidemic… MORE⟩⟩


Drinking coffee can prevent bone loss in your jaw and keep your teeth from falling out.

Researchers from the University of Maryland School of Dentistry recently published an article reviewing the health benefits of coffee in the journal General Dentistry — and much to the chagrin of bone doctors (and a few dentists) everywhere — they dashed a long held belief: that coffee was believed to cause bone loss.

In fact, the latest evidence suggests otherwise…

A 2016 study published in the journal PLoS One found that post-menopausal women who drank the most coffee had better bone density than post-menopausal women who drank the least coffee.

Now, bone loss in the jaw, like most bone loss, is usually caused by osteoporosis… an issue that primarily affects post-menopausal women. When you lose bone density in your jaw, your teeth may become loose and eventually fall out. That’s because your jaw anchors your teeth into your mouth.

So if coffee can help post-menopausal women keep their bones intact, it’s a big win for their teeth too. But besides protecting your jaw bone, coffee has another health-boosting surprise up its sleeve…

Green coffee beans — coffee that hasn’t been roasted yet (available as an extract) — will fight bacteria in your mouth and protect your gums from periodontal disease.

But these benefits, as great as they are, don’t change the fact that coffee’s acidity can soften your tooth enamel and tarnish your pearly whites. That’s why, if you’re going to drink coffee to benefit your teeth and bones, you need to follow a few guidelines to minimize the damage:

  • Drink coffee through a straw so it doesn’t touch your teeth.
  • Rinse your mouth out with water after drinking coffee.
  • Wait at least 30 minutes after drinking coffee to brush your teeth. That gives your enamel time to harden, so you don’t scrub it away.
  • Try natural tooth whitening methods like oil pulling, activated charcoal or apple cider vinegar.
  • Limit yourself to a maximum of five cups of coffee per day.
