Teeth Whitening

White, bright teeth giving you the confidence to smile

As we get older our teeth naturally start to lose their pearly white colour, so we tend to associate white teeth with youth and vigour.

Dark stain from inside the teeth can’t be removed by conventional polishing. Professional tooth whitening works by breaking down stain molecules, bleaching the teeth and brightening the smile.

Here at Cwmbran Dental Care we believe that whitening is a fantastic cost effective way to improve your smile so recommend professional at home teeth whitening kits. We create custom trays for you and supply whitening gel which best suits you.

How does the treatment work?

Firstly we assess the shade of your teeth and take a pre-whitening photo. We then take accurate impressions of your teeth and construct clear, custom moulded trays for you. Once your trays are ready, we invite you back to check the fit and comfort of the trays and take you through how to apply the whitening gel effectively into the whitening trays.

We advise your trays are worn each night while you sleep, so as not to interfere with your speaking or eating, typically for 2 weeks. If you choose to have day whitening, you’ll need to wear the trays for a short amount of time during the day – perhaps while at work or doing house work. Night whitening has a lower concentration of the whitening agent so you can wear it for longer while you sleep.

After 2 weeks we invite you back to review the results and take a post-whitening photo. By comparing your final result with your starting shade, it is really easy to see the difference whitening treatment has made! You may need to whiten for a little longer if your starting shade was dark.

What are the side effects?

Some people find that their teeth become sensitive during the treatment, while others may have discomfort in the gums, or white patches on the gum line. These symptoms are usually temporary and disappear within a few days of the treatment finishing. We can provide you with desensitising products to help with any sensitivity.

Only Dental Professionals can carry out Tooth Whitening

We strongly advise patients to avoid purchasing products from the internet, which can contain damaging acids and abrasives. We also direct you away from attending beauty salons, as they are not allowed to do the work of dentists. In Europe, it is illegal to supply bleaching material containing more than 0.1% peroxide (or the equivalent in carbamide peroxide) to anyone other than a dentist, or directly to the public. These regulations are to protect the public, by making sure that anyone carrying out whitening is properly trained and has the right skills and knowledge to carry out the procedure, without risking permanent damage to the teeth or gums.


  • How white will my teeth go?

    At your first appointment, we take the time to discuss your desired outcome, and the shade of white you can expect your teeth to turn. We take a photo before beginning treatment so you are able to clearly see the difference when your whitening is complete. If your starting shade is very dark, we may suggest wearing your whitening trays for a little longer to achieve your perfect white teeth.

  • Can my crown, bridge or veneer be whitened?

    Whitening treatment is not effective on restorations such as crowns, bridges and veneers. You may wish to consider whitening your teeth before this treatment, so your restoration can be made to match. Alternatively, we can replace your crown, bridge, veneer or partial denture to match your new whiter teeth at an additional cost.

  • Is whitening treatment permanent?

    No, whitening is not permanent, and will need to be topped up if you would like to maintain your results. The duration of your results will vary and be dependent on certain external factors such as drinking lots of tea and coffee or smoking. Typically, whitening lasts anywhere from 6 months to 3 years.

  • Is whitening your teeth painful?

    You may find your teeth and gums become more sensitive, but this should improve once you have completed the treatment.

  • Does whitening do any damage to my teeth

    Tooth whitening as directed by a dentist is very safe and does not involve damaging your teeth in any way.
