Three jobs, one chewable
The mouth aisle sells one idea: kill 99.9% of everything, twice a day. Gum Armor does the opposite. It tends the balance your gums actually answer to.
The good bacteria
Three friendly strains put back every day, so the balance tips the right way.
The bad bacteria
A xylitol base the harmful strains can't digest. Half the method, right there.
The tooth surface
Hydroxyapatite, the same mineral as enamel, stays in your mouth where the work happens.

What the trials measured
In a randomized double-blind trial of 66 adults, 8 weeks of daily L. salivarius tablets significantly reduced the combined count of five bacteria linked to gum problems below the gumline, with the drop showing by week 4.*
In a placebo-controlled trial, adults taking L. paracasei daily showed a significant reduction in mutans streptococci, the main cavity-driving bacteria. The good strain was still detectable a month after they stopped.*
In a 132-person randomized trial, daily xylitol cut mutans streptococci in plaque tenfold by week 5, and it held at 6 months.*

Questions, answered plainly
How is this different from mouthwash?
Mouthwash kills 99.9% of everything, good bacteria included. The harmful strains grow back first, so the cycle repeats. Gum Armor picks a side instead: feed the good, starve the bad, protect the surface.
Why not just take an oral probiotic?
Ordinary oral probiotics do one job: add bacteria. Gum Armor does three. It adds three friendly strains, starves the harmful ones with a xylitol base, and delivers hydroxyapatite, the mineral your enamel is made of. See the side-by-side comparison.
How long until I notice something?
Weeks, not days. Mornings change first. The real answer is your next checkup.
What is actually in it?
Three actives: a 3-strain probiotic, a xylitol and guava base, and microcrystalline hydroxyapatite. The full amounts are printed on the label. No proprietary blend games.
When do I take it?
One chewable, chewed thoroughly, after a meal. Same time each day if you can. Do not swallow whole.
Is it sugar-free?
Yes. The base is xylitol, and that's half the method: the harmful bacteria can't digest it.
Instead of brushing?
No. Brush, floss, keep your dentist. This is the other half of the plan.
Is it safe to take every day?
It's built for daily use. One chewable a day. If you are pregnant, nursing, or managing a medical condition, check with your doctor first.
How does the guarantee work?
Try it for 90 days. If it's not for you, contact us for a full refund and keep the bottle. No return label, no phone call, no hoops.
How does the subscription work?
A bottle a month, with free shipping. Skip or cancel anytime from your account, no phone calls.
What if I have dogs?
Xylitol is toxic to dogs. Keep the bottle where your dog can't reach it, like chocolate or gum.
