About Us
Hey, I'm Killian.
It started with a nag. My girlfriend told me I should floss more, so I did what any reasonable person does: I bought a giant bag of those little plastic flossers and went to town.
A few weeks in, I looked at the bin and saw a pile of tiny plastic sticks I'd used once and thrown away forever. Multiply that by every mouth on the planet and the math gets grim fast.
So I built Dental Guardian: premium oral care that replaces all that disposable dental junk with one beautiful tool you keep for good. Turns out the best thing for your teeth can be the best thing for the planet too. (And yes, I floss every day now. She was right.)
Built Once. Built Right.
Buy it once, keep it for years. The Sentinel is built to outlast every throwaway flosser you'd have burned through in the meantime.

Frequently asked questions
Is it Safe?
Very. Sentinel is ADA certified and made from 316L surgical-grade stainless steel, so there's no BPA, no plastic, and no sharp edges to worry about. One handle covers the whole household, and the replaceable Haven spools mean everyone gets a fresh head every time. Your mouth is in good hands.
Is 10% to the Planet included in the Kickstarter?
Absolutely. Every single pledge counts from day one, no exceptions: 5% goes to global reforestation and 5% to ocean cleanup. You back us, the planet gets its cut.
How is this different from the other flossers?
Other flossers are designed to be thrown away. The Sentinel is designed to stay. The handle is built to last a lifetime, and you simply swap in Haven refill spools the way you'd change a razor blade. So instead of tossing a whole flosser every week, you keep one good tool for good.
How much are floss refills?
Less than you're already spending, honestly. Haven refill spools come in 3-packs that cost less per month than what most families blow on disposable flossers. And founding members lock in a subscriber rate that never goes up. Ever.
What if I don't Like it?
Then send it back, no interrogation required. We offer a no-questions return policy because we're that confident Sentinel will earn its spot on your counter. If it doesn't change your routine, it's on us.
How does the kickstarter work?
Simple. You pledge during the campaign to reserve your Sentinel kit at the founding member rate, our best price ever. Hit the goal and your card is charged and we ship. Miss it, and you're never charged and owe nothing. No risk, all upside.
