The daily rinse

Stain Whitening Mouthwash

612 Reviews

An alcohol-free daily rinse that lifts fresh coffee, tea and wine stain before it has time to set. PAP works on the surface, xylitol discourages the bacteria behind dullness, and the finish is clean rather than medicinal.

The maintenance step. Thirty seconds, morning and evening, between whitening courses.

  2. Rinse for thirty seconds, moving the liquid between the teeth.

Beautiful ingredients.

Three actives, chosen for what they do and left to do it.

Hydrogen Peroxide in a glass dish

Hydrogen Peroxide

The whitening active, used at a gentle daily-rinse level. It breaks down the coloured compounds that coffee, tea and wine leave on the enamel, then splits harmlessly into water and oxygen.

Xylitol in a glass dish

Xylitol

A natural sweetener from fruits, vegetables and birch trees. Sweet on your tongue, invisible to oral bacteria. Decades of dental research backs it.

Eucalyptus Leaf Oil in a glass dish

Eucalyptus Leaf Oil

A cooling botanical oil pressed from the eucalyptus leaf. It carries the clean, long-lasting freshness of the rinse without alcohol, so there is no sting and no dryness afterwards.

Vegan
Alcohol free
Sugar free
Enamel safe

Recyclable bottle

Beautiful results.

It holds and gently improves the shade you have. For a shade change, run the fourteen-day strip course and keep the rinse as maintenance.

★★★★★

No sting at all

Every other whitening rinse I have tried left my mouth dry and burning. This one does not, and the taste is clean rather than clinical.

Keeps the coffee at bay

I rinse after my morning espresso and the tea-coloured film I used to get by lunchtime has gone.

Niklas BergströmSwedenVerified purchase

★★★★★

Bottle lasts

Five weeks from one bottle with two people using it sparingly. Reasonable for the price.

Gentle on my gums

My gums are prone to irritation and this has caused none in three months of daily use.
