How long does teeth whitening last?

Professional dentist-supervised teeth whitening typically lasts 12–24 months. Most patients remain significantly lighter than their starting shade, and regular top-up whitening can maintain results indefinitely.

Will my whitened teeth return to their original colour?

It is uncommon for teeth to return fully to their original shade. Most patients remain 1–2 shades lighter long term, and simple top-up whitening prevents meaningful relapse.

How often should I top up teeth whitening?

Most patients need 1–2 nights of top-up whitening every 4–6 months. Heavy tea, coffee, or smoking habits may require top-ups every 3–4 months. One syringe usually lasts several maintenance cycles.

Is long-term teeth whitening safe?

Yes. Decades of research show that dentist-supervised peroxide whitening does not damage enamel or dentine. Sensitivity is temporary and reversible when whitening is used correctly.
