Your mouth is home to hundreds of species of bacteria. Some of them protect you. Some of them cause the plaque, the film, and the morning breath you keep brushing away. Most oral care treats them all the same way: kill everything, rinse, repeat tomorrow.
There's a problem with that approach. The killing only lasts a few minutes, and then everything grows back. The good, the bad, all of it, racing to recolonize. Nothing about the balance changes. That's why the same film shows up by lunch, every single day.
The other way: take sides
Researchers have spent the last two decades studying a different idea. Instead of wiping the slate clean over and over, you can tilt the balance. Back the helpful bacteria so they hold more territory, and take food away from the harmful ones so they hold less.
That's the thinking behind oral probiotics. In one randomized double-blind trial, adults who took daily L. salivarius tablets for 8 weeks showed a significant reduction in the combined count of five bacteria linked to gum problems below the gumline, with the drop showing by week 4.*
The starving half
The other half of the strategy is xylitol, a sweetener from birch trees. The bacteria behind plaque grab it like sugar, but they can't digest it. They waste energy on it and produce less of the acid that causes trouble. It's a decoy, and it's one of the most studied ingredients in dentistry.
Why we built a chewable around this
Gum Armor puts both halves in one daily chew: three probiotic strains to feed the good, a xylitol base to starve the bad, plus hydroxyapatite, the same mineral your enamel is made of. We call it the Feed + Starve Method. It's not a replacement for brushing. It's the other half of the plan, for the 23 hours a day your toothbrush isn't working.
One chew a day. Backed by the 90-day guarantee.
