Grey Street Dentist proudly offers teeth whitening to patients in the local St Kilda, St Kilda East, Balaclava, Elwood, Albert Park, Middle Park, Windsor and Prahran areas.

There are many methods of whitening, some better (and safer) than others. To save yourself some time trawling through the internet, we have done extensive research into what tooth whitening gets the best long term results without harming your teeth. Please remember not all methods are suited to everyone so it is best to come in for a chat to assess what will work best for you.


We generally recommend this method of whitening as the results we get are amazing and they last up to 18 months. It is also the most cost effective. Once you have the tooth whitening trays and finish the initial tooth whitening kit, you can whiten when you like and buy refill syringes.

At Grey Street Dentist, our cosmetic dentists use Opalescence which is one of the leading tooth whitening brands. Depending on which concentration you use (day or night), it is made up of 10% or 15% Carbamide Peroxide which is a safe, gentler bleaching agent. It’s a sticky, viscous gel that includes Potassium Fluoride (PF), which helps to improve oral health by strengthening enamel, decreasing sensitivity, and offering increased cavity prevention.

So how do you use it? Basically you squeeze the tooth whitening gel into a specially made tray and you wear it overnight (or during the day depending on what suits your lifestyle) which is super easy! Depending how white you would like to go we tell patients they will need to do this for 7-10 nights/days. Most of our patients have tubes of gel left over which they can use to ‘top up’ at a later stage, which just brightens them up a bit. In terms of how white you will go, you can expect to whiten 5-7 shades lighter than your current tooth colour. On your initial visit we take a ‘before’ photo so you can see where you are currently on the shade guide, then when you come back for your check up/clean later down the track we will take an ‘after’ photo so you can see how much it has actually whitened.


This method is also available and works in a similar way except it is done in the practice with a stronger gel concentration. This appointment takes about an hour and a half. The upside is it’s quick and easy. The downside is the colour change doesn’t last as long and you have no control on how white you go. We do this course of whitening on a case by case basis as it may have adverse affects on some people, so consult a dentist before going ahead.
