A periodontist's view

“Oral care is built to clean the mouth. Very little is built for the tissue itself.”

Dr. Sarah Chen — DMD, MS, board-certified periodontist

Dr. Sarah Chen

Before you buy.

The six things people check first.

How it works

Toothpaste and rinses clean the whole mouth, then leave in thirty seconds.

This one is a gel. It forms a film along the gum line and stays there — which is why you don't rinse it off.

Ten seconds a day
  • Two pumps onto a clean fingertip
  • Run it along the gum line, top and bottom
  • Don't rinse. Leave it

Best done last thing at night, after brushing, when nothing else goes in for eight hours.

What's inside

Eleven ingredients. All listed. No "proprietary blend", no mystery fragrance.

  • Sodium hyaluronate — holds water at the tissue
  • Cellulose gum — forms the film that stops it washing off
  • Panthenol — pro-vitamin B5, soothes tender gums
  • Glycerin — humectant, keeps pulling moisture in
  • Betaine — helps cells hold their water
  • Xylitol — the sugar bacteria can't feed on
  • Water — what the hyaluronic acid holds

Plus the preservative system and pH adjusters, all named on the label.

Is it safe

Gentle enough for daily use on tender tissue. No alcohol, no SLS, no abrasives.

Safe alongside crowns, veneers, implants and braces.

The gap

  • Toothpaste cleans the surface.

  • Floss gets between.

  • A rinse washes over the top.

All three leave in thirty seconds.

The gum line is not a surface. It is soft tissue that needs to stay hydrated, and nothing that rinses away can do that.

The science

How it works

Saturate · Bind · Hold.

Toothpaste and rinses clean the whole mouth, then leave. This one is for the tissue at the gum line, and it is built to stay there.

01

Saturate.

Hyaluronic acid, glycerin and betaine pull water into the tissue and hold it there.

02

Bind.

A light gel film forms along the gum line instead of running off it.

03

Hold.

No rinsing. It keeps working after you have walked away from the sink.

Six published trials. The same conclusion in every one.

Read them yourself

Ten seconds a day

Once a night, before bed.

The whole point of this one is that it asks almost nothing of you. If it took two minutes you would stop by week three, and it would not matter how well it worked.

  • 01 Two pumps Onto a clean fingertip, or a cotton bud if you would rather not use your hands.
  • 02 Along the gum line Top and bottom, front and back. It needs contact, not pressure.
  • 03 Do not rinse And do not eat or drink after. That is the part people get wrong.
  • 04 Leave it Last thing at night, when nothing else goes in for eight hours.
Ten seconds a day 8wk per bottle, at
two pumps a night.

What is inside

Eleven ingredients. All eleven listed.

No proprietary blend, no mystery fragrance. Six of the eleven are doing the work.

And the seven we refuse

Highlighted are the six doing the work. The rest are the preservative system and pH adjusters, all named on the label.

The serum holding at the gum line

What to expect

Honestly told, in three stages.

“Week four is where most people quit. It is also where it starts working.”

  • Weeks one to two The tightness eases. Comfort rather than change. The tissue holds water again, so it stops feeling drawn.
  • Weeks four to eight The line stops moving. Nothing dramatic. Things stop getting worse, which after years of the opposite is the point.
  • Month three onward The same numbers as last time. Your hygienist measures what she measured last time. Nothing new to write down.

It will not grow tissue back. Nothing will.

If a month passes and nothing has changed, use the guarantee. We would rather refund you than have you keep buying something that is not working.

In their words

Not louder. Just steadier.

Every review is from a verified purchase. We do not edit them, and we do not only publish the flattering ones.

    “Wasn't sure about this.”

    Bought it half expecting nothing, after everything else I have tried. It does not sting, you do not rinse it off, and it takes ten seconds. My gums feel less tight already.

    Deborah H. · 5 weeks in

  • Maureen E.

    “Nothing's moved since.”

    My dentist told me to keep an eye on it and come back in six months, which felt like being told to do nothing. Nothing has moved since, and that is the first time in four years.

  • Kathleen P.

    “You forget it's there.”

    No taste, no sting, and the whole thing takes ten seconds. I do it last thing at night and forget about it entirely.

  • Sharon W.

    “It actually stays put.”

    I was sure it would just wash away like everything else I have tried. It does not. Still there in the morning.

    Sharon W. · 3 months in

  • Angela R.

    “The burn was the problem.”

    Every rinse I tried stung. This one does nothing at all, which turns out to be the point.

    Angela R. · 2 months in

    “My hygienist noticed.”

    She asked what I had changed. That has never happened at a check-up before.

    “Ten seconds is nothing.”

    I have stuck with it because it asks for nothing. That is the whole reason it works.

    That went in the first month. The rest has been slower, but it has held.

A periodontist's view

Formulated with people who see gums every day.

“Oral care is built to clean the mouth. Very little is built for the tissue itself.”

Most brands want a name on the box. This one wanted the claims cut back until every single one could be defended in front of a colleague. Nothing brings back what is gone. This supports what is still there, and that is what it says.

Have questions?

Choose your mouth. Choose Holy.

Answered straight, including the ones with an awkward answer.

  • My gums are fine?

    Gum tissue thins slowly and quietly. Most people find us after they have noticed something, but nothing here requires a problem to be useful.

    • Ten seconds a day
    • Nothing to change in your routine
    • Easier to hold a line than to wish you had
  • When will I notice?

    Comfort is fast. Holding the line is slow, and it is the one that matters.

    • Comfort and hydration — first two to three weeks
    • Holding the line — months, not weeks

    Give it a real run before you judge it, and use the guarantee if a month passes and nothing has changed.

  • Will it wash away?

    Most things you put in your mouth are gone in thirty seconds. Water-thin, and your saliva does the rest. This one is a gel. Cellulose gum turns it into a film that clings to the gum line instead of running off it. That is why you do not rinse, and why night works best.

    Ten seconds of applying. Eight hours of staying.

  • Can gums grow back?

    No. Gum tissue that has receded does not come back, and anyone telling you otherwise is selling you something. We could have written this page differently. We would rather you heard it from us.

    What you can do is support the tissue you still have. That is the whole job of this product, and it is a smaller promise than the category usually makes.

  • Why has no dentist told me?

    Most will say keep an eye on it and come back in six months. That is reasonable advice, and it is also not a task.

    • Dentists treat. Monitoring is what happens between treatments
    • Nothing about a daily serum competes with that
    • Ask yours. Most have no objection to it

    The gap is not that nobody cares. It is that nobody assigned you anything for the wait.

  • Instead of mouthwash?

    No. It replaces nothing. Rinses clean the whole mouth and leave. This sits on the gum line and stays. Different job, different place, no overlap.

    • Keep brushing
    • Keep flossing
    • Keep your check-ups

    Use it after you brush, last thing at night.

  • Just expensive water?

    Water is the first ingredient, and it is meant to be. Hyaluronic acid is a water-holding molecule, so water is what it holds. The cost is not in the water.

    • Hyaluronic acid, glycerin and betaine hold moisture at the tissue
    • Cellulose gum is what stops it washing off
    • Panthenol is what makes it comfortable on tender gums

    Eleven ingredients, all listed. Check any of them.

  • Can I eat after?

    Yes, though you will get more out of it if you do not. The longer it sits undisturbed, the longer it works, which is why we suggest last thing at night when nothing else is going in for eight hours.

    Morning works too. Just leave twenty minutes or so before coffee.

  • How do subscriptions work?

    One bottle is eight weeks, so the default delivery matches how fast you use it. Pick your frequency at checkout and change it any time. Bottles piling up? Slow it down rather than cancelling.

    Two clicks from your account, or reply to any email and we will do it for you.
