For the espresso that came after.

A full course lifts the stains. Coffee, tea and red wine bring some back. The pen puts the same PAP chemistry exactly where you need it, in a few minutes of brushing on.

How to use it

Brush on. Smile on.

Five steps, the first one only once.

Step 1
Brush

Clean teeth first, then dry them briefly.

First use
Prime the pen

Take the cap off and twist the base until gel reaches the tip. A click is normal.

Step 2
Paint a thin layer

On the teeth you want to lift. Avoid gums and lips, and keep your mouth open while it settles.

Step 3
Wait 15-20 minutes

No eating or drinking.

Step 4
Rinse

Rinse thoroughly with water.

Holding the pen and its box

Unlike most PAP kits, the dose is stated.

PAP is an ingredient, not a dose. Ours is 12 %, in every WeSmile gel. Independent lab testing of a 12 % PAP gel put numbers on what that dose can do:

Whiteness index · 12 % PAP8.82
Hydrogen peroxide · 37.5 %4.48
Carbamide peroxide · 35 %4.16

Llena et al. 2026, lab study on extracted teeth. It tested another manufacturer's 12 % PAP gel, not ours.

Why the number matters

Touch-ups work best after a course.

Questions?
Fair ones.

Straight answers, including the ones that cost us a sale.

Pen or Starter Kit?

The pen is for keeping and touching up. If you are starting from scratch, the Starter Kit does the heavy lifting, with our stated PAP12% gel and the money-back guarantee.

Does it hurt?

There is no hydrogen peroxide in it. Teeth that are already sensitive can still react; if they do, pause for a day.

How long does a pen last?

4 ml covers about 30 treatments.

Will it whiten crowns or fillings?

No. Whitening only works on natural enamel.
