The Science

Every Northwhite treatment is built on a simple idea: a whiter smile shouldn't come at the cost of healthy enamel.
Here's how the full system works, from your first application to long-term maintenance.



Our non-peroxide formula works in two phases, first lifting stains through gentle oxidation, then remineralising and protecting your teeth with hydroxyapatite.


Together, these two phases mean your results don't fade once the tray comes off. Daily care keeps stains from returning, deep repair strengthens enamel from within, and the app keeps your routine on track so your smile keeps improving, not just staying the same.

Teeth Whitening Strips

FAQ's

Will I Experience Any Sensitivity?

No. Our exclusive non-peroxide formula lifts stains gently, giving you a brighter smile without irritating sensitive teeth or gums.

When Will I Start Seeing Results?

Each box contains 28 strips for a full 14-day course. Most customers notice a visible difference within the first few days, with the fullest results appearing once the full course is complete.

How Do I Use The Teeth Whitening Strips?

  1. Make sure your teeth are completely dry before applying, for the most even fit.
  2. Apply one strip at a time: the longer strip on your upper teeth, the shorter on your lower.
  3. Press each strip down firmly, folding it gently around the back of your teeth to secure it in place.
  4. Leave the strips on for 30 minutes. Avoid eating or drinking during this time.
  5. After 30 minutes, gently peel the strips away.
  6. Buff away any residue with your toothbrush or a tissue, rinse thoroughly, and enjoy your brighter smile.

For best results, use daily across the full 14-day course, or until you reach your desired shade.

How Long Will My Results Last?

Once you've reached your ideal shade, results typically last 8 to 12 weeks. After that, simply repeat the course, or use a strip once a week to maintain your brightness.
