A Measured Whitening Step for Everyday Stains

Want to address visible staining without preparing a tray or measuring gel? Smile Dew puts the formula on two flexible strips, ready for your upper and lower teeth.

Focus on Surface Stains

These PAP teeth whitening strips are intended for external staining associated with coffee, tea, red wine and strongly coloured foods. Results depend on the cause of the staining and your starting shade.

Know What Is in Your Formula

PAP, listed as Phthalimidoperoxycaproic Acid, is the whitening ingredient. Hydroxyapatite and xylitol are also included, with no added alcohol. Check the complete ingredients accordion before buying.

Keep Your Usual Oral Care

Whitening is an additional step. Continue your regular brushing routine with fluoride toothpaste and follow the strips' own directions. A 14 treatment pack makes the quantity clear. It does not guarantee a particular shade change or mean the product suits every type of discolouration.

How to Use Teeth Whitening Strips

Prepare: Make sure your teeth are clean and dry. Open one sachet and remove the backing from the strips.
Apply: Position one strip on your upper teeth and one on your lower teeth. Press gently into place.
Wait: Leave the strips on for 30 minutes. Do not eat or drink while wearing them.
Remove: Take off both strips, discard them and rinse your mouth thoroughly.

Use one application daily for 14 days. Do not wear the strips for longer or use more than one application per day.

Stop using the strips if pain, irritation or sensitivity occurs. Ask your dentist for advice before continuing.

What to Expect During Your 14 Day Routine

Results vary with your teeth, the type of staining and your everyday habits. There is no guaranteed shade change or fixed day when results will appear.

Day 1

Day 1: Get the Application Right

Focus on positioning the strips and following the 30 minute wear time. An immediate colour change is not guaranteed.

Day 7

Day 7: Check Under the Same Lighting

If you compare your smile, use photographs taken in the same lighting. A brighter room or camera filter can make teeth look different without a treatment effect.

Day 14

Day 14: Review Your Routine

Finish the course as directed and compare with your starting point. Do not increase the wear time or frequency to chase faster results. If discolouration concerns you or does not respond as expected, speak to your dentist before repeating treatment.

Choose Your Pack

Each application uses one upper and one lower strip. Compare the number of treatments and the cost per application before choosing your pack.

Teeth Whitening Strips FAQs

Read how whitening strips work

Whitening strips can help address external stains, depending on the formula and the cause of discolouration. Smile Dew uses PAP, but the ingredient list alone does not establish a guaranteed result for your teeth.

The strips hold the PAP formula against the tooth surface during the application. Smile Dew's supplied formula contains no hydrogen peroxide or carbamide peroxide. Follow the stated wear time rather than leaving them on longer.

Use one upper and one lower strip once daily for 14 days. Do not use more than one application per day. Ask your dentist if you are unsure about repeating a course.

Each Smile Dew pack provides 14 applications. How long a visible result lasts is different: it depends on your teeth, oral care and habits, with no fixed duration guaranteed.

Sensitivity can occur, and suitability varies. Ask your dentist before use if you have sensitive teeth, enamel damage, decay or gum problems. Stop if you experience pain, irritation or sensitivity.

Apply to clean, dry teeth. After removing the strips, rinse thoroughly as directed. Continue your normal brushing routine with fluoride toothpaste and follow any timing instructions supplied with your pack.

No. Do not eat or drink during the 30 minute application. Remove both strips and rinse your mouth thoroughly afterwards.

Whitening does not change the underlying shade of veneers, crowns, fillings or composite bonding. Natural teeth may change differently from dental work. Ask your dentist before treatment.

The product warning advises seeking medical advice before use during pregnancy or breastfeeding. Do not assume that an ingredient preference establishes suitability.

Each product has its own directions. Do not combine whitening treatments to try to speed up results. Ask your dentist before adding another whitening product to the same routine.

Check the complete ingredients, applications per pack, wear time, suitability information and total delivered cost. Choose using those details rather than a promised shade change or a guaranteed results date.
