Yes. Our formula is dentist-developed to gently lift stains without damaging your enamel. We use a balanced peroxide blend that effectively whitens without the harsh concentrations that can cause long-term enamel wear.

Sensitivity is one of the most common concerns with teeth whitening – but Smilie’s formula is different. Our gel contains desensitisers and soothing agents to protect enamel and gums, making it safe for sensitive teeth while still delivering professional-level whitening.

Teeth whitening results typically last 3–6 months or longer, depending on your lifestyle and dental hygiene. After reaching your desired shade, we recommend a quick top-up treatment every two weeks to prevent new stains and keep your smile bright.

Most customers notice a whiter smile after just one treatment. For the best and longest-lasting results, we recommend whitening once a day for 6 consecutive days (and up to 14 days if you want your brightest smile). Results can vary depending on your tooth structure and the type of stains (coffee, tea, red wine, smoking, ageing, etc.).

We stand by our product. If you’re not completely in love with your smile, our 30-day money-back guarantee means you can request a full refund within 30 days of receiving your kit – no risk, no hassle.
