The words “peroxide-free” often appeal to those looking for a more natural or gentle approach to teeth whitening. But does it really work — and is it right for you?
Instead of using hydrogen or carbamide peroxide (the active ingredients in most whitening treatments), peroxide-free options rely on ingredients like:
These are generally marketed as natural or less abrasive, with the aim of brightening teeth without triggering sensitivity.
If you're looking for subtle whitening or are highly prone to sensitivity, peroxide-free might suit your needs — but it won’t deliver the same level of results as professional-grade peroxide treatments.
At High On Smile, we use peroxide-based gels that are carefully formulated and applied to minimise sensitivity while delivering professional results — often in a single session.
We always prioritise safety and comfort, and can advise on which approach is best for your smile goals.
