Gums get very little attention in most oral care routines, even though they are the first thing to feel it after whitening. HA5 is a hyaluronic acid serum made for exactly that tissue. It is lightweight, non-greasy and applied after brushing.
Why it earns a place in your routine:
- High concentration hyaluronic acid (HA) retains moisture, so gums feel hydrated and supported.
- High molecular weight HA is there to soothe inflammation and support the mouth's natural healing process.
- Post-whitening recovery is its clearest job: apply it after a whitening treatment to calm sensitive tissue.
- It is a leave-on formula, so there is no rinsing and the HA stays on your gums all day.
How it fits your day: Use it twice daily as the final step of your oral care routine, and again after any whitening treatment. Full ingredients and usage directions are listed in their own sections on this page.
Why Pro White Teeth Kits: The brand was founded as an alternative to whitening products that rely on peroxide, carbamide or bleach, which can irritate gums and increase sensitivity. Its whitening range uses the PAP-X formulation, free from peroxide, bleach and carbamide. HA5 is the soothing side of that approach: it looks after the gums rather than the shade.
Pairs well with: NHpro Enamel Care Serum, from the same brand, is made to repair and remineralise enamel overnight using nano-hydroxyapatite technology. It is a natural nightly companion to HA5 if sensitivity is your main concern.

About Pro White Teeth Kits
The teeth whitening market is often saturated with products that promise rapid results but come with the risk of gum irritation, enamel damage, and increased tooth sensitivity due to harsh ingredients like peroxide, carbamide, or bleach. Pro White Teeth Kits was founded to provide a clear alternative, offering a whitening solution that delivers noticeable brightness without these common drawbacks.
What truly distinguishes Pro White Teeth Kits is their exclusive PAP-X formulation, meticulously developed to be entirely free from peroxide, bleach, and carbamide. This commitment ensures that users can achieve a brighter smile without compromising the health of their enamel or experiencing soft tissue irritation, making it a standout choice for those prioritising safety and comfort.
Beyond its gentle formulation, Pro White Teeth Kits holds the distinction of being the only vegan-certified teeth whitening range in the UK. This reflects a deliberate brand philosophy that prioritises a low-risk approach, selecting active ingredients for their safety profile and consistent results over time, rather than chasing immediate but potentially harmful whitening effects.
