What is teeth whitening, and who is it for?
Teeth whitening uses a peroxide-based gel to lift stains and make teeth look brighter. There are at-home kits with custom trays, and in-clinic systems that use light or laser to speed up the result.
Before whitening, the dentist checks your oral health and usually recommends a scaling first for an even result. Whitening works on natural teeth but does not change the colour of fillings, crowns or veneers.

Frequently asked questions
How long does whitening last?
Does whitening make teeth sensitive?
At-home vs in-clinic — what's the difference?
How much does whitening cost?
Will whitening also lighten crowns or veneers?
What is whitening, and why do teeth yellow?
Teeth whitening uses a bleaching agent to reduce dullness and surface stains for a brighter look. Teeth commonly yellow from tea, coffee, wine and smoking stains, from age, or from the natural colour of the tooth.
The different whitening systems
At-home bleaching — a custom tray with whitening gel used at home as the dentist advises.
In-clinic (Cool Light / Laser / ZOOM) — the dentist whitens at the clinic with fast results in one visit.
Some cases combine both for a more even, longer-lasting result.
Does it cause sensitivity? Who is it for?
Some people feel temporary sensitivity during or after whitening, which usually settles on its own. It suits people with healthy teeth and gums; decay or gum inflammation should be treated first, and those pregnant or breastfeeding should consult the dentist first.
How long does it last, and how to care for it
Brightness can last months to a year depending on diet and care. Cutting back on tea, coffee, wine and smoking, brushing regularly and coming for scaling on schedule all help the result last longer.
In-clinic whitening vs a DIY kit
In-clinic whitening is supervised by a dentist with a suitable strength and gum protection, for fast, even results. Off-the-shelf kits are weaker and can irritate the gums if used incorrectly — whiten under a dentist's guidance.
