I’m going to let you know one thing most dentists gained’t.
For 40 years, I watched sufferers do every thing proper — brush twice a day, floss, lower the sugar — and nonetheless lose enamel. Nonetheless grind their enamel at evening. Nonetheless get up exhausted. Nonetheless come again with extra sensitivity, extra recession, extra harm.
However, in lots of instances, the issue wasn’t their toothbrush or floss.
It was a mineral deficiency that nearly no person checks for — and that in line with NHANES information, 48% of American adults have proper now with out realizing it.
Magnesium.
I do know. You’ve most likely heard of it. You may even already take it.
However what I’m about to share modified the way in which I follow dentistry, and it would change the way in which you concentrate on your enamel, your sleep, and your mind.
Your enamel might not be capable to restore themselves with out it.
Magnesium is a part of your enamel. A 2016 examine in Acta Biomaterialia discovered that magnesium ions react with tooth enamel via a course of referred to as dissolution and re-precipitation — actually restructuring the crystal lattice on the floor — and the end result was more durable, extra resilient enamel. A follow-up examine in Acta Biomaterialia (2020) confirmed it: roughly a 20% enhance in nanohardness.
However right here’s the place it will get scary…
When your magnesium is low, your saliva loses the flexibility to deposit calcium and phosphate again into your enamel. That course of — remineralization — is how your enamel repair tiny cracks and harm each single day. With out sufficient magnesium, that restore system can sluggish to a crawl — or stall solely. You can have the perfect brushing routine on the planet, and your enamel should still be shedding floor.
Take into consideration that. Your physique has a built-in tooth restore system. And most of the people might have by chance turned it off.
Your mind is shrinking. Magnesium might sluggish it down.
A 2023 examine within the European Journal of Vitamin (Alateeq et al.) tracked over 6,000 adults ages 40–73 and measured magnesium consumption towards mind quantity on MRI. The discovering stopped me chilly: individuals consuming greater magnesium had brains that appeared roughly one yr youthful by age 55. Bigger whole quantity. Fewer white matter lesions. Higher-preserved areas for studying and reminiscence.
One yr youthful. From a mineral that prices pennies a day.
Girls noticed even larger neuroprotective advantages within the Alateeq examine — and the reason being alarming. Between 30 and 40% of menopausal ladies have scientific hypomagnesemia (low magnesium) with out realizing it. Estrogen helps regulate magnesium retention, so when estrogen drops throughout perimenopause and menopause, magnesium plummets with it. And magnesium is what permits your physique to truly use vitamin D — so in the event you’re supplementing vitamin D (as most ladies over 40 are instructed to), it might not even be working with out ample magnesium. It’s a cascading failure that nearly no person is connecting the dots on.
Wow! Bigger brains. Fewer lesions. Measurably youthful construction. And this wasn’t a small examine — it was over 6,000 individuals tracked with MRI. The researchers even discovered that the neuroprotective advantages of upper magnesium have been larger for ladies than males throughout each measure they checked out.
Should you’re anxious about staying sharp as you age — about reminiscence, about focus, about your mind simply… working — this one mineral might matter greater than nearly something I’ve seen in 40 years of studying analysis.
This might be why you’re grinding your enamel at 3am.
A double-blind, placebo-controlled scientific trial printed within the Journal of Analysis in Medical Sciences (Abbasi et al., 2012) gave topics 500mg of magnesium each day for 8 weeks. The outcomes: statistically important will increase in sleep time, sleep effectivity, and melatonin ranges — and important decreases in cortisol (the stress hormone) and sleep onset latency. They fell asleep quicker. They stayed asleep longer. Their stress hormones dropped.
When my sufferers began sleeping higher, one thing surprising occurred: they stopped grinding and clenching at evening.
The jaw relaxed. The enamel stopped cracking. The sensitivity dropped.
I take magnesium each evening, 1–2 hours earlier than mattress. If I skip a dose — particularly when touring or in a brand new time zone — I discover.
Now — essential caveat from a dentist who’s been skilled in sleep drugs: magnesium will not be an alternative to treating a sleep respiratory dysfunction. Should you snore, gasp, or cease respiratory at evening, that’s a distinct dialog solely, and you must see an AADSM-trained dentist or sleep doctor or you possibly can even begin with a session with a myofunctional therapist. However for the tens of millions of people that don’t get sufficient magnesium — who lie awake, who wake at 2am, who by no means really feel rested — this mineral is the very first thing I’d take a look at.
Sleep isn’t nearly power. Sleep is when your physique repairs. Your mind prompts the glymphatic system — clearing beta-amyloid and tau proteins linked to Alzheimer’s and cognitive decline. Your mouth restores its protecting mineral steadiness. Minimize your sleep high quality, and every thing downstream suffers — blood sugar, anxiousness, cravings, blood stress. I’ve seen it in 1000’s of sufferers.
Right here’s what terrifies me about most magnesium dietary supplements.
After I spotted how crucial magnesium was, I began taking a well-liked model. Good label. Sturdy evaluations. I felt good about it.
Then I learn the unbiased lab outcomes.
I pay for a membership to ConsumerLab — an unbiased lab that’s been testing dietary supplements since 1999. They’re not sponsored by any model. They purchase merchandise off the shelf, check them for purity, efficiency, and contamination, and publish the outcomes. Consider it like Client Reviews, however for dietary supplements. Their testing has flagged a number of widespread magnesium merchandise for contamination with lead, cadmium, and arsenic. The very factor I used to be taking to guard my well being might have been quietly including to my poisonous load. I finished instantly.
And that’s not the one drawback. Most dietary supplements include only one type of magnesium. However your physique makes use of magnesium in tons of of various processes — your mind wants a distinct kind than your muscle mass, which want a distinct kind than your bones and enamel. Taking only one kind is like placing fuel in your automobile however by no means altering the oil, the coolant, or the brake fluid.
There are seven crucial kinds, and each targets one thing completely different. Most merchandise offer you one. Possibly two.
Right here’s what most individuals don’t understand till it’s too late.
You may’t essentially really feel when a magnesium deficiency is occurring.
Commonplace blood checks don’t even catch it — solely about 1% of your physique’s magnesium is in your blood serum, and NHANES hasn’t even measured serum magnesium ranges in its nationwide well being survey since 1974. You can be deeply poor and your labs would look completely regular. The medical system actually isn’t in search of it.
By the point you discover the delicate enamel, the mind fog, the jaw ache, the insomnia — it’s attainable that, by that time, you’ve been operating on empty for years. And each day with out sufficient magnesium is a day your enamel, your mind, and your sleep fall a little bit additional behind.
Right here’s how deep this goes:
A 2017 randomized scientific trial (Tarleton et al., PLOS One) discovered that magnesium supplementation produced clinically important enhancements in each despair and anxiousness — and the results confirmed up in simply two weeks. Whoa.
A dose-response meta-analysis in BMC Drugs (Fang et al., 2016) discovered that each further 100mg/day of dietary magnesium was related to a 22% decrease danger of coronary heart failure. A separate meta-analysis in Diabetes Care discovered the same dose-response: each 100mg/day increment was linked to a 14% discount in sort 2 diabetes danger throughout 13 cohort research involving over 536,000 individuals.
And a landmark 2018 paper within the Open Coronary heart journal referred to as subclinical magnesium deficiency “a principal driver of heart problems and a public well being disaster.” Not a contributor. A principal driver. And that’s a peer-reviewed cardiovascular journal saying it.
This isn’t one thing you repair later. Later is how individuals find yourself with cracked molars at 55, or early cognitive decline, or a mouth filled with dental work that would have been prevented.
What I personally take — and why I switched.
After the heavy steel scare, I spent months researching. I wanted a magnesium that was third-party examined for purity, and that contained all seven kinds so my mind, my muscle mass, my bones, my enamel, and my nervous system have been all really getting what they wanted.
I discovered one. It’s the one one I’ve come throughout that checks each field — and it handed ConsumerLab’s unbiased testing for purity, efficiency, and heavy metals.
You may see precisely what it’s and why I vetted it right here, however I’ll say this:
Since switching, my enamel are much less delicate. My sleep is deeper. My spouse and I each take it. It’s maybe the one complement that if I have been pressured to drop every thing else, I’d preserve.
See the precise magnesium I take each evening.
Almost half of us are poor. Virtually none of us understand it. And the results are silent till they’re not.

P.S. I’ve had sufferers inform me this one change — simply getting the correct magnesium — did extra for his or her enamel than years of costly dental work mixed. I want I might return and inform each affected person I’ve ever had. As a substitute, I’m telling you.
