In-Office Teeth Whitening: What to Expect from a Professional Session

Cosmetic dentistry, including teeth whitening, has seen a steady increase in demand in Sydney in recent years. People in Sydney, like in many other major cities, are increasingly seeking ways to improve their appearance, including enhancing their smiles.

While there are various whitening options available, in-office teeth whitening in Sydney is often considered the most effective and fastest way to achieve noticeable results. This article will walk you through what to expect from a professional in-office teeth whitening session so you can make an informed decision if you're considering this treatment.

The Consultation:

Prior to your in-office teeth whitening treatment, it is customary to undergo a consultation with your dentist. In this session, your oral health will be evaluated to determine your eligibility for teeth whitening. Additionally, your dentist will engage in discussions regarding your expectations, objectives, and the specific level of whiteness you desire.

Pre-Treatment Examination:

Prior to commencing the whitening procedure, your dentist will conduct an extensive inspection of both your teeth and gums. This is essential to identify any dental issues that need to be addressed before whitening. For example, cavities or gum disease should be treated before proceeding with teeth whitening to avoid complications.

Shade Assessment:

Your dentist may take a shade assessment of your teeth before starting the treatment. This involves comparing the current color of your teeth to a shade guide, which helps in tracking the progress and measuring the improvement after the treatment.

Protecting Your Gums and Lips:

To safeguard your gums and lips from the whitening gel, your dentist will apply a barrier or a protective gel. This ensures that the whitening agent only comes into contact with your teeth, reducing the risk of irritation or sensitivity.

Application of Whitening Gel:

The core of the in-office teeth whitening procedure is the application of a professional-strength whitening gel. This gel typically contains a higher concentration of hydrogen peroxide or carbamide peroxide compared to over-the-counter whitening products. The dentist will evenly apply the gel to the surface of your teeth, ensuring that each tooth receives an adequate amount of the whitening solution.

Activation with a Special Light:

In some cases, a special light may be used to activate the whitening gel. The light helps to accelerate the whitening process, letting the gel penetrate the tooth enamel more effectively. This step is often repeated for several cycles, each lasting about 15-20 minutes, depending on the whitening system used.

Monitoring and Adjustments:

During the treatment, your dentist will closely monitor the progress and adjust the whitening process as needed. They may check the shade of your teeth and make any necessary modifications to achieve your desired level of whiteness.

Rinse and Assessment:

Once the desired level of whitening is achieved or after a set number of cycles, the dentist will rinse off the whitening gel thoroughly. They will then assess the results to determine if any additional sessions are required to reach the desired shade.

Post-Treatment Instructions:

After the in-office teeth whitening session, your dentist will provide you with post-treatment instructions. This could encompass dietary guidelines, including the avoidance of dark-coloured foods and beverages known to stain teeth. Furthermore, your dentist may provide specific recommendations for oral hygiene practices to uphold the brightness of your newly whitened smile.


In-office teeth whitening in Sydney is a safe and effective way to achieve a brighter, more dazzling smile quickly. During the procedure, your dentist will carefully assess your oral health, apply a professional-strength whitening gel, and closely monitor the progress to ensure you achieve your desired results. If you're considering teeth whitening, consult with your dentist to determine if in-office whitening is the right choice for you.
