Tooth Whitening or otherwise known as bleaching is a technique used to lighten the enamel shade of teeth. The general process involves the application of a bleaching agent onto the tooth surface. Most bleaching agents are comprised of a Hydrogen Peroxide formula. Depending on the system chosen by your dentist, the strengths of the bleaching agents can vary.

Here at Courtney Dental we recommend the Designer White Advance Professional Tooth Whitening System.

The recent study conducted by the Indiana University School of Dentistry's Oral Health Research Institute has shown that Designer White ADVANCE promotes the remineralization of teeth during the whitening process and may reduce tooth sensitivity.

The process is quite simple, a set of custom made trays are fabricated and the patient applies the gel into the tray and wears them for an hour over a period of time until the desired shade is achieved.

Some general advantages of whitening/bleaching:

  • Bleaching is ideal for undamaged teeth that need lightening in colour. (As opposed to crowns, veneers or facings) 
  • Custom made trays can be used again at a later stage 
  • Upper and lower teeth can be treated at the same time from one procedure 
  • Approved tooth whitening products are safe to use

Some disadvantages of whitening/bleaching:

  • Not all teeth respond well to bleaching. For example, yellow, brown and orange stained teeth usually respond well to bleaching. However, grey stains may lighten a little, but results may not be as good.
  • Not all teeth bleach evenly 
  • White composite restorations do not get affected by the bleaching process and may need to be replaced after the process in order to achieve a nice aesthetic result 
  • If the bleaching agent has a prolonged contact with the gums it can lead to irritation and burning 
  • Bleaching should be done in a controlled setting. Some store bought whitening systems can be very strong and can damage teeth over a long term period. We do not recommend such treatments. 
  • Bleaching may not be suitable for people with; pre-existing sensitivity, cracked teeth, worn teeth, receding gums or periodontal disease.

In general, it is important to consult with your dentist before commencing any form of teeth whitening. There may be specific considerations that need to be taken into account with your teeth.
