Every few weeks, someone forwards me a video, more or less following the same script:
“Dentists don’t want you to know this!”
“Two drops of this oil, massaged into your gums, and your receding gums grow back!”
The bad news is you can’t regrow gum tissue that’s already gone, but the good news is that you have control over stopping that recession.
The tissue you still have, you can protect, starting today, and that’s what we’ll discuss in today’s email.
First, though, 30 seconds on why “regrow your gums” is a myth, because once you understand it, no viral video can ever fool you again.
Why gums don’t grow back
Your gum has two parts: the pink tissue you can see, and the attachment you can’t—collagen fibers anchored into the root, a thin mineral layer on that root, and bone underneath. The attachment is what holds your gumline at its height. Recession is the loss of that attachment. The visible gum is following that foundation down.
So why can’t your body rebuild it? When the attachment is destroyed, the surface gum heals over the wound at the new, lower level, long before the slow-growing bone and fibers can rebuild what was lost. Quick patch, sealed shut. And once it’s sealed, there is no rebuilding of the lost attachment. To your body, it’s a closed wound protecting you from an open sore in a bacteria-filled mouth, and it will not reopen the site to rebuild what was lost.
A graft can restore gum coverage, but it does so surgically. It doesn’t make the original attachment spontaneously grow back. Absolutely a procedure worth doing when it’s needed. Just know what you’re getting.
So why do the before-and-afters look so real?
Because inflamed gums are swollen gums. Calm that inflammation, and the swelling drops, the bleeding stops, and the gumline looks fuller and pinker within a couple of weeks.
The person filming genuinely believes their gums grew back. But they didn’t; it’s just that the swelling went down. (Think of a sprained ankle’s puffiness fading versus the ligament actually healing—they look alike from the outside.)
So here’s the test that cuts through every viral video: An exposed root is darker, more sensitive to cold, and often notched at the neck of the tooth. If it’s still exposed after your miracle routine, your gums didn’t grow. They just got less inflamed. This isn’t a bad thing, perse, it just isn’t the same as gum regrowth.
How recession sneaks up on you..
Recession is usually slow enough to be nearly invisible. Plaque sitting at the gumline keeps the tissue chronically inflamed: redder, puffier, more fragile, always in repair mode. At that stage, which is gingivitis, the attachment under the gum is still intact, and the whole process is reversible. Calm the inflammation and the tissue recovers completely. (That, by the way, is the stage those viral videos are operating in.)
But in susceptible people, inflammation turns into periodontitis, and now the attachment itself starts breaking down, bone remodeling away, the gumline drifting down the root behind it. You can lose a fraction of a millimeter at a time, over years.
So don’t wait for something dramatic. Bleeding, puffiness that won’t resolve, pockets that get deeper at every cleaning, a gumline that’s crept—these are signals to find out why the tissue is inflamed, while there’s still plenty of attachment left to protect.
What actually works
In rough order of impact:
- Find out why it’s happening. It’s better if we think of recession as a symptom, rather than the final diagnosis. The two biggest drivers I saw over four decades were gum disease and grinding. And grinding is usually a red flag for something on the spectrum of sleep-disordered breathing. If you’re wearing your enamel and your gums are pulling back, the question isn’t “what DIY remedy”—it’s why is my mouth under this much force and/or inflammation?
- Stop brushing like you’re scrubbing a pan. Hard bristles and heavy pressure abrade the gumline directly. Switch to a soft or extra-soft brush, hold it like a pencil in your left hand (if you’re right-handed, and in your right hand if you are left-handed), and use small, gentle, circular sweeps. Replace the bristles every four weeks, which is more expensive, but guarantees you won’t be brushing with sharp, worn-out bristles that inflict damage to gums. If it’s an electric brush, let the brush do the work for you so you avoid overbrushing. If your brush bristles are splayed out after three weeks, you’re pressing far too hard.
- Treat the grinding at the root, not just with a night guard. A night guard protects your teeth from the force, and I want you to have one. But it’s a band-aid. Grinding and clenching are often your body fighting for an airway during sleep. If you snore, wake up tired, or wake with a dry mouth, get your breathing evaluated. Fixing the airway is fixing the cause. If you don’t know where to begin, start with my book “The 8-Hour Sleep Paradox” available on Amazon.
- Calm the inflammation without scorching your mouth. This is where an oil-pulling blend earns its place. Swishing a good oil blend for a couple of minutes gently lifts debris and soothes inflamed tissue, without the collateral damage of an antiseptic mouthwash, which clears out the beneficial bacteria along with everything else and leaves your mouth worse off. I use one every morning (this is the blend).
- Feed the cellular energy your gum tissue runs on: CoQ10. Your gum tissue is metabolically busy, and CoQ10 is the fuel that busy tissue runs on. The evidence here is honest and modest: a recent meta-analysis found that oral CoQ10, taken as an add-on to a real cleaning, produced a small, sub-millimeter improvement in gum pocket depth and attachment. It’s one of the few supplements I take specifically with my gums in mind (link to mine.)
- Build the collagen your gums are actually made of: vitamin C and zinc (link for the one I recommend). Longtime readers will see where this is going. Your gum attachment is collagen, and you do not build collagen by swallowing collagen. Your gut just breaks that powder down into amino acids you already have plenty of. The real bottleneck is the machinery that assembles collagen, and that machinery runs on two specific cofactors: vitamin C, which powers the enzymes that lock collagen fibers into their final shape, and zinc, which your cells need both to switch on the collagen gene and to manage the enzymes that remodel the tissue. Give your gums those two and you’re supplying what that attachment is built from.
- Round out the support: magnesium, D3/K2, omega-3s, green tea. All of the following are supportive. Magnesium supports tissue repair, D3 with K2 helps route minerals to bone and tooth, omega-3s calm inflammation body-wide, and the compounds in green tea interfere with the very enzyme—collagenase—that gum-disease bacteria use to break down that collagen attachment. An oral probiotic helps the beneficial species crowd out the troublemakers rather than killing everything indiscriminately.
- Protect the exposed root itself: a hydroxyapatite varnish. The part almost everyone misses: once a root is exposed, it’s not just sensitive — it’s vulnerable. Root surface is softer than enamel, and it decays faster. What you can do is harden and protect it. That’s the job of a nano-hydroxyapatite varnish: the hydroxyapatite sinks into the exposed surface, quiets the cold-zing sensitivity (often within days), and remineralizes the soft root so it’s far more resistant to decay. It’s the exact job I formulated Fygg’s varnish for. You dab it right on the sensitive spot. It’s the tool I always reach for the moment a root is exposed.
- If you’re considering a gum graft, fix the cause first. Grafting is expensive, technique-sensitive, and not something you want to keep repeating quadrant by quadrant because the original problem was never corrected. Once whatever’s driving the recession (inflammation, traumatic brushing, grinding, tooth position) is stable, see a periodontist who does a lot of root-coverage surgery, and ask three questions: How much of my exposed root can you realistically cover? What technique would you use, and why? And how predictable is that result in my particular case? The gold standard for many recession defects is still a coronally advanced flap with a connective-tissue graft, usually borrowed from your palate; tunnel techniques, donor tissue, and regenerative materials are options in some cases. With the right anatomy, complete or near-complete root coverage can be remarkably predictable. But not every root can be fully covered, especially when bone and attachment have already been lost between the teeth. A successful graft really can give you new, living, thicker gum tissue over the root. What it doesn’t reliably do is regenerate the entire original attachment—bone, ligament, and the mineral layer on the root, as though the recession never happened. The tradeoffs are real: surgery, cost, healing time, some temporary discomfort (especially where tissue is taken from the palate), and the possibility of incomplete coverage or recurrence. That’s why I want the cause stopped before the graft: do it at the right time, do it well, and ideally do it once.
The goal
Think of your gum like the weather-seal around a door. When it’s intact, it keeps out everything that doesn’t belong. When it wears back, you can’t grow new rubber, but you can stop whatever was wearing it down, and protect what you’ve still got for the rest of your life.
That’s the reframe I want you to walk away with.
If someone’s sent you one of those “regrow your gums” videos or if you’ve spent money on one—hit reply and tell me which one. I’m collecting them, and calling them out is becoming a bit of a mission of mine.
This should be incredibly motivating: in the best long-term study we have, hundreds of people who got their gum recession under control were followed for thirty years, and in all that time, and only 21 teeth were lost to gum disease or decay in the entire group, in all that time.
Stop the cause, and the gumline you have today is the one you keep.
You’ve got this,
Mark
