Cosmetic teeth whitening is a quick treatment, but what you do in the following days also matters. This guide explains the usual aftercare advice, including the so-called "white diet", so that you can look after your smile with confidence.
Why aftercare matters
Straight after whitening, teeth may be more receptive to colour from food and drink. Avoiding strongly coloured products for a short period helps you enjoy the effect of the treatment for longer.
The "white diet" in practice
For the first 24 to 48 hours, many clients choose light-coloured foods and drinks, for example:
- still water and milk
- plain rice, pasta and potatoes
- chicken, white fish and mild white cheese
- cauliflower, bananas and peeled apples
It is generally advisable to avoid or limit:
- coffee, black tea, red wine and cola
- beetroot, berries, tomato sauce and curry
- soy sauce, balsamic vinegar and dark chocolate
- smoking and nicotine products
Daily care afterwards
- brush gently twice a day and clean between your teeth
- drink water after coloured drinks, or use a straw
- keep up regular dental check-ups and professional cleaning
Sensitivity
Some people notice temporary sensitivity to cold or heat. If you have sensitive teeth, gum problems, fillings or crowns in visible areas, please mention it before the treatment. Cosmetic whitening does not replace dental care; if you have pain or an untreated dental problem, see your dentist first.
Frequently asked questions
How long should I follow the white diet?
Usually for the first 24 to 48 hours. Your therapist will give you specific advice after your treatment.
Can I drink coffee after whitening?
It is best to avoid it at first. Later, drinking water afterwards or using a straw can help.
Will crowns or fillings whiten as well?
No. Whitening affects natural tooth enamel, not crowns, veneers or fillings. Please mention them at the consultation.
