Professional Teeth Whitening In Sydney

Professional teeth whitening offers numerous benefits for patients looking to brighten their smile. Some of the most significant advantages of teeth whitening include:

• Improved appearance: Professional teeth whitening can brighten the overall appearance of your smile.
• Safe and effective: Professional teeth whitening is a safe, effective cosmetic treatment, performed by trained dental professionals with extensive experience.
• Long-lasting results: With proper care, professional teeth whitening results can last for years, making it an extremely cost effective treatment.
• Stronger Formula: Professional treatment provides a stronger concentration of bleach, meaning a more effective result than at-home or DIY kits.
• Even coverage: Custom-made trays fit the exact shape of your teeth, ensuring all surfaces are covered for even bleaching.

During your initial consultation, your dentist will work closely with you to discuss your expectations for treatment and answer any questions you may have. They will also perform a thorough examination of your teeth and gums to check you’re suitable for Zoom teeth whitening. If you have any underlying dental issues, such as gum disease, your dentist may recommend steps to treat them first. Prior treatment will likely incur extra costs.

When you arrive for your appointment, your dentist will start by protecting your lips and gums before applying a bleaching gel to your teeth. An LED light is then positioned over the gel to speed up the whitening process, and this step is repeated a few times with fresh gel each round to build up the results. Once the whitening is complete, a fluoride treatment is applied to help protect your enamel and keep any sensitivity to a minimum.

Our dentists at No Gaps Dental will advise you on which foods and drinks to avoid initially, to ensure effective treatment results. We also provide sets of custom-made whitening kits to help maintain and extend the longevity of your results. The lifespan of Zoom teeth whitening depends on lifestyle factors. Smokers and avid coffee, alcohol, tea, and soft drink consumers may experience staining post-treatment.

While store-bought teeth whitening kits cost less than in-chair treatments and offer a convenient option, they don’t have the same impact as professional Zoom teeth whitening. They contain a low concentration of bleach, so you won’t see as stark a result as you can get from a professional service.

Dental professionals are the only people legally responsible for administering teeth whitening products with over 18% carbamide and 6% hydrogen peroxide. Depending on the brand, they may also contain unsafe or unregulated chemicals that cause negative side effects.

At-home kits tend to be one-size-fits-all, which can contribute to uneven whitening and gum aggravation.

That said, our teeth whitening services at No Gaps Dental include take-home kits following your professional appointment, to help maintain your whitened smile. These kits are custom-made to fit your teeth, so they don’t carry the same risk of uneven whitening or gum irritation. You should use these kits following your dentist’s instructions, and take care not to overuse the bleach.

As per Australian law, dental professionals are the only people legally responsible for administering teeth whitening products with over 18% carbamide and 6% hydrogen peroxide1. This means results will have a more effective, evident impact on the yellowing of teeth while remaining safe under professional supervision. 

There is no one-size-fits-all explanation when it comes to how long your teeth whitening will last. Patients can expect results to last one year, depending on lifestyle and oral hygiene habits. Ensuring teeth are properly cared for following a teeth whitening treatment will improve the longevity of results.

Smokers or patients who drink alcohol, coffee, tea or soft drinks often, are more likely to experience stains and discolouration post-treatment compared to someone who doesn’t.

Zoom whitening, when performed by a dental professional, is a safe and effective way to brighten your teeth. The main active ingredient, hydrogen peroxide, does not damage tooth enamel when in moderation and properly. However, it’s important to be aware that the treatment can cause temporary sensitivity, which usually fades within a few days.

However, overusing teeth whitening products or misusing them can potentially damage the tooth enamel, leading to tooth sensitivity or even tooth decay. For this reason, it’s always best to consult your dentist before beginning any teeth whitening treatment. That way, you can ensure your teeth whitening regime is appropriate for your specific dental needs and learn how to use the product safely and effectively.
