Why the serum?

  • Targets sensitivity:Seals exposed dentinal tubules for fast, lasting relief from hot and cold sensitivity.
  • Rebuilds enamel overnight:Concentrated HAP absorbs while you sleep, filling microscopic enamel gaps and strengthening surfaces.
  • Soothes gum tissue:Hyaluronic acid and chamomile calm inflammation and hydrate the gum line.
  • Whitens naturally:HAP fills surface pores that trap stains, boosting whitening results without peroxide or abrasives.
  • No rinse formula:Designed to stay on teeth overnight so HAP has maximum time to bond and repair.
After brushing, dispense 2–3 drops onto a clean fingertip. Gently massage into the gum line and sensitive areas. Do not rinse. Use nightly for best results.
Calcium Hydroxyapatite (HAP), Hyaluronic Acid, Aloe Vera, Vitamin E, Xylitol, Chamomile Extract, Zinc Citrate. Free from fluoride, alcohol, and artificial preservatives.

How to use

Three steps to your best smile.

The serum works alongside your regular brushing routine for targeted, concentrated HAP treatment.

1
Brush as normal
Use Fresq HAP Refresh Toothpaste for your regular 2-minute brush. This primes your teeth and removes surface debris.
2
Apply the serum
Dispense 2–3 drops onto a clean fingertip. Gently massage into your gum line and any sensitive areas.
3
Leave it on
Don't rinse. The serum absorbs into enamel and continues working overnight. Use nightly for best results.

Targeted treatment

Applied where your teeth need it most.

Unlike toothpaste, the HAP Protect+ Serum delivers a concentrated dose of hydroxyapatite directly to problem areas — sensitive zones, enamel-worn surfaces, and the gum line.

  • Sensitive zones near the gum line
  • Enamel-worn surfaces and exposed dentine
  • Areas prone to plaque build-up
  • Post-whitening or post-treatment recovery

What to expect

Results you'll actually feel.

🦷
Sensitivity relief
Most users notice a significant reduction in hot and cold sensitivity within 2 weeks of nightly use.
Visibly smoother enamel
HAP fills microscopic enamel gaps, leaving teeth feeling and looking noticeably smoother within 4 weeks.
💜
Healthier gums
The serum's gum-contact formula supports tissue health, reducing redness and inflammation at the gum line.
Accelerated whitening
Used alongside the toothpaste, the serum supercharges your whitening routine without abrasives or peroxide.

How HAP works in the serum

The serum delivers a concentrated dose of nano-hydroxyapatite directly to your enamel surface — giving HAP maximum time to bond, fill, and repair while you sleep.

Gone in two weeks

I've had sensitive teeth for years. Two weeks of using the serum every night and the sensitivity is almost completely gone. I can drink cold water again without wincing.

The perfect pairing

I use the toothpaste in the morning and the serum at night. My teeth have never looked or felt better. My dentist asked what I was doing differently.

Doesn't get enough credit

This serum is the unsung hero of oral care. The dropper makes it easy to apply exactly where you need it. My gum line looks healthier than it has in years.
