Teeth Whitening / Bleaching

Welcome to a whiter brighter smile. Teeth whitening can be the most simple and affordable way of getting a new smile. Having teeth look whiter and brighter can give you more confidence.

Teeth whitening is a procedure that involves using a chemical like 6% hydrogen peroxide gel. This gel penetrates through the outer enamel layer to whiten the darker dentin layer. The dentin layer can be yellow, grey or brown in colour. As the gel lightens the dentin, this gives the appearance of whiter teeth.

There are generally 2 ideal procedures for teeth whitening. In chair whitening and take home whitening. In chair whitening like Zoom, uses a higher concentration whitening gel and a blue UV light to accelerate the whitening procedure. Take home whitening involves a lower concentration bleaching gel and customised bleaching trays.

The Procedure
Take home teeth whitening systems.
A consultation with your dentist is required to assess if you are a suitable candidate for bleaching. People with thin enamel or have teeth that are heavily restored may not be great candidates. An initial shade of your teeth will be taken so that you have a baseline to compare against and expectations and desired cosmetic outcomes will be discussed.

If suitable, impressions of your upper and lower teeth will be taken, and custom made bleaching trays will be fabricated. Your dentist will then explain to you how to correctly use the the teeth whitening system.

Frequently Asked Questions (FAQ)

Q. What is the difference between in office bleaching and take home bleaching?

A. The main differences between in office bleaching and take home bleaching is times, sensitivity and control. In office bleaching can be completed within 1-2 hours, however because of the need to use a higher concentration of bleach and the shortened treatment time, teeth can become more sensitive and thus a more painful treatment option. The only advantage is that you can walk out of the dental office with whiter teeth.
Take home bleaching, although slower as treatment times range from 1-2 weeks, allows for more control of the bleaching process. It is a great option if you would like to whiten gradually and decide how white you would like your teeth to be. There is less sensitivity as well.

Q. How long do my teeth stay white for?

A. The ability for your teeth to stay whiter longer depends on how often you drink coffee, tea and red wine or consume foods that may stain, ie curries that may contain cumin and beetroot. Smoking also contributes to discoloured teeth.
During the bleaching process and especially 2 weeks after the bleaching process, you should also refrain from consuming foods and liquids that may discolour your teeth, as you don’t want these staining molecules to enter your pores within the teeth, thus making things worse.

Q. How do dental professional teeth whitening procedures compare to supermarket, pharmacy or shopping centre products?

A. Supermarket and pharmacy products like teeth whitening pens, strips and gels all work to a small extent, but because they are sold in lower concentrations than dentist sold whitening products, the effects are minimal. Dentist supplied systems also provide you with custom made dental trays which reduces waste and ensures an accurate bleaching process. The most important factor in favour of using dentist supplied teeth whitening products is the advise and follow up. Most of the off the shelf teeth whitening systems do not have warnings with regards to diet and those companies will definitely not ring you to see how your teeth whitening treatment is going.
