How to use this one

You'll need to combine this toothpaste with your Nudge toothbrush. Hunker down for a couple of minutes (that's how you get that shine!). And for what it's worth, make an effort to brush in a circular motion from top to bottom.

Dosage

Splash your toothbrush with a pea-sized drop of toothpaste 30 minutes after finished eating.

FAQ

Questions

Are you third party tested?
Yes. Each batch is tested by independent labs for identity, heavy metals including lead, arsenic, mercury and cadmium, micro limits, and stability.
Is nano hydroxyapatite safe for daily use?
The European Union Scientific Committee on Consumer Safety concluded that nano hydroxyapatite is safe in toothpaste within specified limits. Our formula uses 10%, which is within those limits.
Do you contain fluoride?
Nudge Toothpaste is fluoride free. In the United States only fluoride actives are recognized under the FDA anticaries monograph for cavity prevention claims.
Can I use it with a fluoride rinse or paste?
Yes. Hydroxyapatite and fluoride can complement each other in remineralization. You can alternate or pair them. For personal guidance ask your dentist.
Does it help with sensitivity?
Clinical trials have reported reductions in dentin hypersensitivity over about eight weeks with toothpaste that contains 10% to 15% nano hydroxyapatite.
Will it whiten my teeth?
Studies report that hydroxyapatite can smooth enamel and lift surface stains, which can improve brightness. Results vary based on diet and brushing habits.
Is it suitable for kids?
Yes, with supervised brushing. Use a pea size amount and encourage spitting. Hydroxyapatite is biocompatible and has been studied in pediatric settings.
How abrasive is it?
We formulate for daily use without harsh grit. The ADA notes that dentifrices with a Relative Dentin Abrasivity of 250 or less are acceptable for everyday use. Contact support if you want the exact RDA for your lot.

Why We Don’t Claim 10% Nano-Hydroxyapatite on Packaging

At Nudge, we believe in science, transparency, and integrity—not
misleading marketing claims. Many brands boldly state “10%
Nano-Hydroxyapatite” on their packaging, but few disclose the full truth
about how this ingredient is formulated.
