The #1 nHAp brand trusted by dentists
KeraHAp™ is the first peptide-enhanced nano-hydroxyapatite toothpaste, an advanced fluoride-free formula designed to promote stronger enamel, fresher breath and whiter teeth, with no peroxide and no harsh abrasives.

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™.
Shop the bundle“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
Rely on peroxide to bleach teeth, an extra step many people find leaves teeth feeling sensitive.
Many scrub stains away with harsh abrasives tough on enamel when used every day.
Brightens by lifting stains and smoothing enamel while peptides and nHAp support stronger enamel. No trade-off.


Twice a day, morning and night, following the 30-2-30 rule above
KeraHAp™ pairs Dr. Jen's premium 10% nano-hydroxyapatite with peptides that help guide new mineral onto your enamel, the first formula of its kind.
nHAp binds to surface stains and fills tiny pores in enamel, so teeth reflect light more evenly for a naturally brighter smile.
Peptides help organize new mineral growth, supporting the replenishment of enamel for a stronger, smoother surface.
Dr. Jen's proprietary essential oil blend helps curb bad breath while promoting a healthy oral microbiome.
In two independent lab studies, KeraHAp™ delivered greater remineralization than prescription 5,000 ppm fluoride, over-the-counter fluoride toothpaste and MI Paste®.
