How to use

What to expect from your whitening pen

The pen is intended for external surface stains. What you notice depends on your starting tooth colour, the cause of staining and your routine.

Drying in 30 seconds does not mean whitening in 30 seconds. A particular shade change or results date is not guaranteed.

Whitening does not change the colour of veneers, crowns, fillings or composite bonding. Ask your dentist before using a whitening product around dental work.

For unexplained discolouration, tooth pain or existing sensitivity, get dental advice before starting.

Whitening that fits the way you apply it

Want to apply gel to individual teeth without fitting a strip or filling a tray? A brush gives you control over placement. If you are choosing a whitening pen for teeth affected by everyday surface stains, Smile Dew offers that format in a compact 2ml pen.

A brush for precise placement

A brush for precise placement

Twist the base and use the tip to spread a thin layer over the tooth surfaces. There is no separate gel bottle to handle.

A choice you can check

The gel needs 30 seconds to dry. Choose a time when you can then leave 30 minutes before eating or drinking.

How to use the teeth whitening pen

Follow these directions from the product packaging. Apply a thin layer and keep the two timings separate.

  1. Twist: Turn the base of the pen to dispense gel onto the brush tip.
  2. Apply: Brush a thin layer onto the tooth surfaces.
  3. Let it dry: Smile and allow the gel to dry for 30 seconds.
  4. Wait before eating or drinking: Leave 30 minutes after application. No rinsing is required.
  5. Follow the frequency: Use once or twice daily as directed.

Do not swallow the gel. Stop using it if pain or irritation occurs, and seek dental advice if symptoms continue.

Customer reviews

Teeth whitening pen FAQs

Do teeth whitening pens work?

They are intended for surface staining, but the result depends on the formula and the cause of discolouration. Smile Dew uses PAP for this purpose.

A fixed shade change is not guaranteed. Whitening products do not treat decay or every cause of discolouration.
How do I use this teeth whitening pen?

Twist the base, brush on a thin layer and let it dry for 30 seconds. Avoid food and drink for 30 minutes. No rinsing is required.

Follow the full directions and the instructions on your pack.
How often can I use it?

The packaging says once or twice daily. Do not increase the frequency to chase faster results. Stop if pain or irritation occurs.
Does it whiten teeth instantly?

No instant shade change is promised. The 30 second instruction refers to drying the gel, not the time needed to see whitening.
Are teeth whitening pens safe, and what side effects should I consider?

Suitability depends on the product and your dental health. Sensitivity or gum irritation can occur. Stop using the pen if you experience pain or irritation.

Ask your dentist before use if you have sensitive teeth, gum problems, recent oral surgery or dental work. Follow the warnings on your pack.
Does the formula contain hydrogen peroxide?

Hydrogen peroxide and carbamide peroxide are not in the supplied ingredient list. PAP, listed as Phthalimidoperoxycaproic Acid, is the whitening ingredient.
How long does a 2ml pen last?

That depends on how much gel you apply and how many tooth surfaces you cover. The pen contains 2ml; a fixed application count is not specified.

Follow the thin layer directions and any expiry information on your pack.
How does the pen compare with whitening strips?

A pen lets you brush gel directly onto individual tooth surfaces. Strips use an upper and lower strip with a set wearing time.

See the format comparison to choose by application method.
Can I use it on veneers, crowns or fillings?

Whitening does not change the colour of artificial dental work. Ask your dentist about suitability before using the pen around restorations.
Does this replace my toothpaste?

No. Keep your regular fluoride toothpaste and normal oral care routine. The pen is an additional cosmetic step.
How much is UK delivery?

Standard delivery is £4.99, or free on orders of £50 and over. Express is £6.99. See delivery details for estimated total times.
Can I return the pen after opening it?

Our voluntary 30 day change of mind offer requires the pen to be unused and in its original sealed condition.

Faulty or misdescribed goods are treated separately. Your statutory rights remain. Read the Returns & Refunds policy.
