Teeth whitening: what’s safe and what to expect

Teeth naturally darken over time — from tea, coffee and smoking, from some medicines, or simply with age. Professional whitening lightens the natural colour of your teeth safely and noticeably, often in a single visit.

How professional whitening works

We check your teeth and gums first, because whitening works best — and most comfortably — on a healthy mouth. Then we protect your gums and apply a professional whitening gel that breaks down stains within the enamel, lifting the overall shade.

What results can you expect?

Most people see a clear difference straight away. How far your teeth can lighten depends on their starting shade and the kind of staining: yellowish stains usually respond well, greyish stains less so.

Is it safe?

Yes, when it’s carried out or supervised by a dentist. Some people feel temporary sensitivity for a day or two, which settles on its own. What we don’t recommend: strong over-the-counter products with unknown ingredients, charcoal powders, or abrasive “whitening hacks”, which can wear away enamel.

How long does it last?

Results often last many months, and sometimes longer — it depends on your habits. To keep your smile bright:

• Rinse with water after tea, coffee or cola.
• Don’t smoke.
• Keep up regular scaling and polishing.
• Ask us about occasional top-ups.
