Teeth whitening
Several shades brighter in an hour
In-office bleaching gel is applied to the teeth and activated with light, usually over two or three cycles in a single appointment. Teeth typically lighten by several shades the same day. Mild sensitivity for a day afterwards is common.

Good to know
- Avoid coffee, tea, red wine, curry and smoking for 48 hours.
- Temporary cold sensitivity is normal; a desensitising toothpaste helps.
- Have scaling first if there is plaque or tartar, as most clinics require it.
- Crowns, veneers and fillings do not change colour and may need replacing to match.
Questions
How long does the effect last?
Often 1–2 years, depending on diet, smoking and home maintenance.
Does it work on veneers or crowns?
No. Bleaching only affects natural enamel, so artificial surfaces keep their original shade.
Can scaling and whitening be done the same day?
Yes, most clinics scale first and whiten afterwards within a single visit.
What if my teeth are sensitive?
The dentist checks your enamel and gums first and may lower the gel strength or advise a different approach.
