It's a sensitive subject

That sudden "zing"? It's real, and it's fixable.

Sensitivity happens when the softer layer inside your teeth (dentine) is exposed. Tiny channels in it run straight to the nerve. Here's how it goes, and how it stops.

  1. Dentine gets exposedBrushing too hard, acidic food and drink, gum recession, tiny cracks, or wider channels from birth.
  2. Something sets it offHot coffee, cold water, ice cream, sweets, citrus. Even a toothbrush.
  3. The Comfort Pen stops itCalms the nerve for fast relief and seals the channels, so the zing fades for good.

How it works

6 modes of action. One result: Comfort.

Two ingredients desensitise. Four keep the gel working where it's needed.

Good to know

The questions we get asked most. All FAQs

Does it work instantly?

Relief builds with each application. You'll notice the biggest difference with regular use over several days.

How often should I use it?

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

Pregnant, under 18, fillings or crowns?

Fine with fillings and crowns. Under-18s can use it under adult supervision. We don't recommend it during pregnancy.

Should I see a dentist instead?

Keep up regular check-ups. If sensitivity is severe, sudden, or doesn't improve, speak to your dentist, as it can be a sign of an underlying issue. Find a dentist
