Teeth whitening at home

Your dentist will give you a teeth whitening kit, with trays and gel, to take home. The tray should be worn as recommended by your dentist and most people wear them overnight. It may take a few weeks to achieve the shade of white you’re looking for.
How should you care for your teeth afterwards?
We recommend the following to help your results last as long as possible:
- Regular check-ups with your dentist and visits to the hygienist for a scale and polish
- Properly cleaning your teeth at home
- Stopping or at least cutting down on smoking
- Cutting back on foods and drinks which can stain your teeth
Is teeth whitening right for you?
You’ll need to be at least 18 and your teeth and gums must be healthy, so your dentist will check this for you. If you’re pregnant or breastfeeding, it’s best to delay having your teeth whitened because it’s not yet clear whether the bleaching products can affect the baby.
Bleaching products can’t lighten the colour of any crowns, veneers, bridges or dentures. If your dentist decides you’re not suitable for bleaching, you could consider veneers or crowns for any particularly discoloured or damaged teeth.
What about ‘over the counter’ home whitening kits?
Many UK pharmacies and websites sell teeth whitening kits or whitening strips to use at home. Just be aware that these products don’t always work, and some of them can permanently damage your teeth. We advise that you get teeth whitening done under the guidance of a dental professional.
