What matters when comparing strips
- Active ingredient: peroxide type/concentration influences whitening strength and sensitivity risk.
- Wear time: a cheaper strip is not automatically more convenient if each session is much longer.
- Treatment count: compare the full course, not just package price.
- Sensitivity: stop if irritation becomes significant and ask a dentist if you have existing sensitivity, restorations or dental disease.
