Professional teeth whitening uses a peroxide-based gel to lighten the colour of natural teeth. It does not whiten fillings, crowns or veneers, and results vary depending on the cause of discolouration. Common side effects include temporary tooth sensitivity and gum irritation. A dental examination is required before whitening to check for decay, gum disease and other factors that may make whitening unsuitable.
Your dentist or oral health therapist will assess your teeth and gums and discuss whether whitening is suitable for you. Whitening does not change the colour of fillings, crowns or veneers.
We offer two options: Take-home Teeth Whitening and In-Chair Teeth Whitening. Your clinician will discuss which, if either, is appropriate for you.
Take-home whitening uses custom-made trays and whitening gel. Your dentist or oral health therapist will explain how much gel to use and how long to wear the trays for your prescribed product.
Treatment duration and results vary. Tooth sensitivity and gum irritation can occur. Contact your dental practitioner if you develop symptoms or have questions about continuing treatment.
In-chair whitening involves applying whitening gel to the teeth at the practice. Your dentist or oral health therapist will assess suitability and discuss the proposed product, treatment time, costs and alternatives.
The degree of colour change varies and cannot be guaranteed. Sensitivity and gum irritation can occur, and whitening does not change the colour of restorations such as fillings, crowns or veneers.
Teeth whitening is an elective cosmetic dental treatment. A dental examination is required to assess your teeth, gums and the cause of discolouration before treatment.
Whitening can cause tooth sensitivity and gum irritation. Results vary, some discolouration will not respond, and existing fillings, crowns and veneers do not whiten. Your clinician will discuss these limitations, alternatives and costs, including the option of no whitening treatment.
Follow the instructions given for your prescribed whitening product. Contact your dental practitioner if you experience symptoms or are unsure about using it. Further whitening should be discussed with your clinician.

An examination is required to assess whether whitening is suitable. Your clinician will discuss decay, gum disease, exposed roots and any other care that may be needed before whitening.
The degree and duration of colour change vary between individuals. Follow your clinician’s advice on oral hygiene, dental cleaning and any further whitening. Use take-home products only as directed. Sensitivity and gum irritation can occur. Stop whitening and contact your dentist if symptoms are significant or persistent.
We’re at Suite 21, 14 Edgeworth David Avenue, three minutes’ walk from Hornsby Station and a short stroll from Westfield Hornsby. Saturday appointments are available (8:30am–4pm). Your clinician will advise on appointment length and aftercare. Free street parking is available nearby.
Take-home whitening is $449, in-chair whitening is $549, and our complete package (in-chair whitening plus take-home gels and trays) is $650. See our price list.
The degree and duration of colour change vary. Diet, habits and the cause of discolouration can affect the response. Further whitening should only be used as directed by your clinician.
Whitening is not suitable for everyone and is not risk-free. An examination is needed before treatment. Tooth sensitivity and gum irritation can occur, and recovery varies. Stop whitening and contact your dentist if symptoms are significant or persistent. Read whitening risks, recovery and alternatives.
Whitening does not change the colour of existing crowns, veneers or fillings. This can leave a colour difference between natural teeth and restorations. Your dentist will explain this limitation and the option of no whitening treatment.
We generally recommend postponing teeth whitening while pregnant or breastfeeding.
