Enlighten Sensitivity Bundle

The Enlighten Sensitivity Bundle is a dual-action solution designed to relieve tooth sensitivity at the source while actively repairing and protecting enamel over time. Combining the targeted power of the Comfort Pen with the daily restorative benefits of Enlighten Serum, this treatment delivers both instant comfort and long-term protection in one simple routine.

Whether you’re experiencing sensitivity after professional whitening or dealing with everyday triggers such as hot, cold, sweet or acidic foods, this system works in two complementary ways:

Immediate, targeted relief exactly where sensitivity occurs
Ongoing enamel repair and protection to reduce future sensitivity

The result is not just temporary comfort, but a stronger, more resilient smile that feels healthier day after day.

The Comfort Pen provides fast-acting relief directly at the gum line using a clinically designed gel with potassium nitrate and bioactive glass, helping to calm nerve response and protect exposed areas. Alongside this, Enlighten Serum works as a daily “liquid enamel” toothpaste, helping to micro-repair damaged enamel, reduce sensitivity and support long-term oral health .

Used together, they form a complete sensitivity solution that fits seamlessly into your daily routine or alongside professional whitening treatments.

Frequently Asked Questions

Does the Comfort Pen work instantly, or does it take time?

Desensitisation builds with each application, so you’ll notice the biggest difference with regular use over several days.

How often should I use the pen, and how long do the effects last?

Apply once a day, or whenever you feel sensitivity. The numbing effect is short-term, but the desensitising ingredients build long-lasting relief with repeated use.

Is it safe to use if I’m pregnant, under 18, or have fillings or crowns?

It’s suitable for use with fillings and crowns. Under-18s can you use it under parental supervision. We don’t recommend using it during pregnancy.
