Article 8 Teeth Whitening



What is Teeth Whitening ?

Teeth whitening is a cosmetic procedure which is performed on the patient’s teeth to alter the shade or colour of the patients teeth for cosmetic purposes. If a patient is unhappy with their smile, the dentist can have a consultation with the patient about ways to change their smile so they can be more confident and teeth whitening may be one of the options to improve their smile.


How Does it Work?

Teeth Whitening is a chemical process which relies upon the whitening gel applied to the patient’s teeth which diffuses through the enamel into the second layer of the tooth called the dentine and then whitens the dentine and enamel of the tooth. Dentists provide patients with peroxide based whitening solutions which can be performed either in-chair at the dentist or take-home.



What are the different types of teeth whitening?

There are 3 modes of teeth whitening available and your dentist may recommend one type or recommend a combination of the modes for the maximum effect:


· In chair- teeth whitening a single long session 1 ½ hours of teeth whitening is completed at the dentist with a high-strength teeth whitening solution and protection applied to the gums.

· Take home teeth whitening kits of moderate strength teeth whitening gel may be given to a patient along with customised bleaching trays made of a flexible plastic material which are specially tailor-made to each patient’s teeth and gums

· Take home preformed teeth whitening kits may be recommended by your dentist to whiten your teeth over a 2 week period with daily applications. The trays are ready-made and a one-size fits all type of tray.


Will Teeth Whitening damage my teeth?

Teeth whitening solutions are peroxide based so they will soak into your teeth to remove any surface stains and will lighten the deeper shade of your tooth also. They will not damage the external surface of your teeth but as the chemicals diffuse through the surface of your teeth they can remove surface plaque and the debris from the surface of your tooth which can make your teeth feel temporarily sensitive as they are metaphorically “scrubbed clean” as all the debris plugging the “pores” is removed.



New Trends: Charcoal Toothpaste and Charcoal Powder

Does Charcoal Powder whiten the teeth? Unfortunately, despite social media claims charcoal does not whiten teeth as it has abrasive particles that scratch the surface of the teeth which rather than whitening the teeth, can scratch away the enamel and reveal the yellow dentine layer of the teeth underneath the enamel.


Teeth Whitening at Beauty Salon’s, Teeth Whitening Bars, Mobile Teeth Whitening etc

There are many beauty salon’s and similar businesses offering teeth whitening now as they have identified this service as a highly-desired service. They may use social media to market that they have significantly whitened the teeth with various photographic filters, testimonials and other techniques, but they use a low-strength 5% peroxide solution to whiten teeth as they are not permitted by Australian Law to use higher strength whitening solution whereas dentists are permitted to use up to 40% peroxide. We are also able to check your teeth for cavities, cracks in teeth, sensitivity and gum recession, as these cases may need extra care during whitening or may need treatment to protect the teeth prior to whitening which these beauty parlours are not able to detect. Whitening is always most effective and safest when supervised by your dentist.
