Why choose teeth whitening?

Tooth whitening is the simplest and most popular way to improve the colour of your teeth, without affecting their health. Teeth can become discoloured because of staining from tobacco, coffee, wine, foods, and tetracycline antibiotics. Additionally, teeth become darker and duller with age.

Tooth whitening can restore a brighter, whiter smile and give you that much needed confidence boost.

We offer the following variety of techniques to ensure that you can whiten your teeth safely and comfortably and get amazing results in a short period of time.

Teeth whitening with home bleaching

We have found that home bleaching gives the longest lasting results and is easy to top up over the years. We have monitored our early cases from 20 years ago and the patients’ teeth have always remained whiter than the original colour.

Home bleaching generally involves 3 visits:

1. First step is to take moulds of your mouth to prepare close fitting custom made bleaching trays – the key to effective whitening.
2. At the next visit we run through the home whitening process and supply you with the trays and whitening gels.
3. We will then review the colour and if necessary supply further gel or adapt the technique to get the teeth whiter. Depending on the colour of your teeth at the start of the treatment, the whitening process takes 2-8 weeks.

Teeth whitening with power bleaching

Power bleaching usually requires 1-2 visits of just over an hour relaxing in the dental chair. The procedure involves placing a protective barrier over your lips, gums and soft tissues. Next, the whitening gel is painted onto your teeth and activated by a special light or heat.

The gel is usually refreshed several times during the appointment to get the best results. For longer lasting results power bleaching is usually followed up with a course of home bleaching.

How long do the results last for teeth whitening?

Our experience shows that teeth remain lighter for many years. Although we recommend patients top up the colour every 2-5 years with a week of home bleaching.

What is the youngest age teeth can be whitened?

Normally 18 as this allows the tooth root and nerve to fully develop. Also the level of the gum on the tooth tends to stabilise around this age.

What is the oldest age teeth can be whitened?

There is no upper age limit. We have treated many grandparents who have been motivated to whiten their teeth due to encouragement from grandchildren. Our oldest patient so far was 90.

What complications are there?

If you have any fillings or crowns these will not lighten and may require replacing after your teeth have become brighter. Usually during the whitening process your teeth become slightly more sensitive, however, it should not be painful. Sensitivity stops when the bleaching procedure comes to an end.

What do you think of whitening toothpastes?

We do not recommend whitening toothpastes as we have found they tend to make teeth more sensitive.
