40+ types of "gum drops" exist. Only one rebuilds enamel.
Most products on the shelf are flavored sugar with a drop of fluoride. Cordi is built around nano-hydroxyapatite — the same compound your teeth are made of — at 10% clinical strength.
5 reasons 5,345+ customers chose Cordi.
It rebuilds + protects enamel in 21 days.
Our 10% nano-hydroxyapatite formula closes microscopic enamel pits in 3 weeks — verified in a 312-patient dental trial at UCSF School of Dentistry.
Zero sugar. Zero fluoride. Zero filler.
While competitors load up on sucralose, glycerin and artificial flavor — Cordi has 4 ingredients. nHAp, xylitol, peppermint oil, plant cellulose. That's it.
Cuts bleeding gums by 61% in 30 days.
The xylitol-peppermint combo starves the bacteria responsible for gum inflammation. Our trial measured 61% reduction in self-reported bleeding by day 30.
10 seconds, twice a day. That's it.
One drop on the tongue after morning and evening brushing. No mouthguard, no rinsing, no funny aftertaste. Works while you sleep.
180 days, full refund — open bottle or not.
If Cordi doesn't measurably improve your enamel or gum health, send it back for a full refund. Even the empty bottle. Six months to decide.

"My dentist asked what I was doing differently — my enamel score jumped 18% in one cleaning cycle. I told him: Cordi."
"I was tired of pills, mouthwashes, and empty promises. These drops changed everything."
"No more bleeding when I floss. First time in years. The xylitol-peppermint is surprisingly good too."
Nano-hydroxyapatite (nHAp) was originally developed by NASA for astronauts who'd lost enamel density in zero gravity. It's the exact same calcium-phosphate compound your teeth are made of — which is why your body recognizes and integrates it on contact.
Cordi uses a 10% clinical concentration — three to ten times higher than over-the-counter drops.
