Why tooth whitening?

Tooth whitening is a great way to remove staining and lighten the natural colour of your teeth without removing any of the tooth surface.

Your natural shade can be enhanced by up to six shades lighter. The whole process takes between 1-2 hours to complete and can be repeated if necessary.

Patients can combine this treatment with home whitening which offers more control over the result and the ability to top up your whitening when needed.



We offer a complimentary 15 minute whitening consultation. During this consultation, your treatment co-ordinator with explain the following type of treatments available in more detail:

  • In-chair treatment
  • Combined In-Chair and Home whitening kit
  • Home Whitening Kit – book an appointment to have your impressions taken to create your customised trays and take your current tooth shade.

  • What can I expect to happen when I choose to have my teeth whitened?

    Prior to the treatment session:

    Your dentist will begin with an examination to ensure that the products are suitable for you

    An impression of your teeth will then be taken to enable customised whitening trays to be made for you to take home for future use.

    The in-chair treatment session:

    The in-chair treatment session for teeth whitening lasts for approximately one hour, however the total consultation may take up to two hours, so make sure you wear comfortable clothes. Simply lie back in the chair and ensure that you are comfortable before the treatment starts. Your dentist will place a soft silicone mouth guard in your mouth to protect your lips and allow you to rest comfortably during the procedure. They will then protect your gums, cheeks and lips so that they can apply the whitening solution safely and comfortably. Your dentist will then apply the whitening product to your teeth and activate a special lamp which is used to activate the whitening solution as part of the procedure. They will set the timer for the first of 4 x 15 minute sessions of whitening. Relax in the chair – the timer will indicate when the procedure is due to finish.

  • I have sensitive teeth, can I have whitening treatment?

    Sensitive teeth can be a common side effect of tooth whitening.  We use Philips Zoom! whitening gels which contain special ingredients that are proven to help reduce sensitivity, protect enamel and improve the lustre of teeth for a brighter smile

  • Is teeth whitening safe?

    Yes. Clinical studies have shown that whitening your teeth under the supervision of a dental professional is safe for teeth and gums. Always ensure that products are EU compliant.

  • What are the side effects of whitening?

    The most common side effect is tooth and gum sensitivity. Your dentist will be able to advise you on whether you are a good candidate for whitening and they can also ensure that you are using the right concentration of whitening formula. Philips Zoom! whitening products contain 2 mild desensitising agents, potassium nitrate and Amorphous Calcium Phosphate (ACP), which are proven to reduce sensitivity.

  • How long will my whitening results last?

    Whitening treatments help to reduce existing stains, but through consumption of coffee, soft drinks, or through natural ageing, your teeth may become discoloured again. Maintenance whitening at home can help combat recurring discolouration. At Devonshire Place Dental Practice we use Philips Zoom! whitening products which includes ACP, which has been shown to reduce whitening fadeback.

  • What causes teeth to discolour?

    There are many causes of tooth discolouration. Some of the most common include the consumption of highly coloured foods and drinks such as red wine, coffee and tea. Some medications, ageing, smoking and trauma can also cause tooth discolouration.

  • When will I notice the difference?

    You will see noticeable results in around 1 hour of treatment. The total consultation may take up to 2 hours.

  • Will the whitening procedure be uncomfortable?

    Your dentist will ensure that your mouth is resting in a comfortable position during the procedure and you will still be able to swallow. There is little or no sensitivity reported during Philips Zoom! treatment however you may experience an awareness of the whitening happening.
