From a mother's solution to Dr. Jen's breakthrough.

From a mother's solution to Dr. Jen's breakthrough.

When her daughter became ill and couldn't use traditional toothpaste, Dr. Jen, a dentist and former engineer, began formulating her own.

Over seven years she tested thousands of ingredients to create a clean yet effective fluoride-free toothpaste. Today, as the #1 nHAp brand trusted by dentists, Dr. Jen and her children, Dr. Claudia and Dr. Gabe, have released their most advanced formulation yet: KeraHAp™.

“I searched health food stores and the internet for a toothpaste with proven ingredients, and came up empty-handed. So I created it.”

— Dr. Jennifer Eisenhuth, DDS

Most whitening makes you choose: a brighter smile or healthy enamel.

  • Whitening strips

    Rely on peroxide to bleach teeth, an extra step many people find leaves teeth feeling sensitive.

  • Abrasive whitening pastes

    Many scrub stains away with harsh abrasives tough on enamel when used every day.

  • Dr. Jen's KeraHAp™

    Brightens by lifting stains and smoothing enamel while peptides and nHAp support stronger enamel. No trade-off.

    Frequently Asked Questions

    How does KeraHAp™ whiten without peroxide?

    Instead of bleaching, nano-hydroxyapatite binds to surface stains so brushing lifts them away, and fills tiny pores in enamel so teeth reflect light more evenly. Expect a gradual, natural brightening with daily use.

    What makes KeraHAp™ different from Dr. Jen’s other toothpastes?

    It’s Dr. Jen’s most advanced formulation: the first to pair premium 10% nHAp with peptides that help guide crystal formation and support the replenishment of enamel. The formula is patent pending. In independent lab testing, it delivered 112% more surface microhardness recovery than prescription 5,000 ppm fluoride

    Is it safe?

    Yes. It’s fluoride-free, peroxide-free, low-abrasion and free of SLS and synthetic flavors and colors, and it uses nano-hydroxyapatite, the mineral that makes up most of your enamel.

    What should I notice in the first 30 days?

    With twice-daily brushing, you should notice less plaque buildup, fresher breath and whiter teeth. For best results, spit out the excess but don’t rinse, and wait 30 minutes before eating or drinking.

    What if it’s not right for me?

    Every order is backed by our 30-Day Smile Guarantee. If your expectations aren’t met for any reason, let us know and we’ll provide a full refund.

    I have an egg allergy. Can I use it?

    KeraHAp™ contains eggshell. If you have an egg allergy, check with your doctor before using it.

    How long does a tube last?

    About 10 weeks brushing twice a day, which is why the 3-tube bundle works out to just $0.34 a day.
