Teeth whitening is one of the most popular cosmetic dental treatments in Australia. Many people want a brighter smile, but not all whitening methods are safe when used without professional guidance. Understanding how whitening products work and the possible risks is important before starting any treatment.
Teeth Whitening in Australia
In Australia, only dentists are allowed to use whitening products that contain more than 6% hydrogen peroxide. This rule exists to protect patients from possible harm and complications. Despite this regulation, teeth whitening remains very common. A 2020 Australian Dental Association survey of 25,000 people found that one in five Australians have tried whitening their teeth.
Supervised vs At-Home Whitening
The survey showed that less than half of those who whitened their teeth did so under the supervision of a dentist. Around 53% used whitening kits bought online, from supermarkets, or pharmacies. Nearly 66% of respondents were unaware of the risks of whitening without professional advice. This highlights that many people are not fully informed about safe whitening practices.
Risks of Teeth Whitening Products
According to Professor Walsh of the Australian Dental Association, teeth whitening products can cause side effects such as tooth sensitivity and chemical burns on the gums and cheeks. A dentist is the only professional who can properly assess whether whitening is safe for each patient. Dentists can also manage any risks during treatment. In many cases, stains caused by coffee, tea, or diet can be removed with a professional clean instead of bleaching.
How Often People Whiten Their Teeth
The survey found that whitening habits vary widely among Australians. More than one-third of respondents whiten their teeth about twice a year. Slightly more than a quarter do it every two weeks. Frequent whitening without guidance can increase the risk of enamel damage and tooth sensitivity over time.
What Research Says About Whitening Gels
Research from the University of Toronto raised concerns about the effects of whitening gels. The study found that some whitening products can affect tooth enamel. A 10% carbamide peroxide gel was shown to reduce enamel protein content by up to 50%. Stronger gels, including 35% concentrations, are also available online. These findings highlight the importance of using whitening products under professional supervision.
Why Professional Advice Matters
Not all teeth respond to whitening treatments in the same way. Some stains and dental restorations do not respond to bleaching products. A dentist can assess your oral health and determine if whitening is suitable for you. They can also recommend safer and more effective options based on your needs.
Final Thoughts
Teeth whitening can improve the appearance of your smile, but safety should always come first. Using whitening products without guidance may lead to unwanted side effects and potential damage. For the best and safest results, always seek advice from a qualified dentist before starting any whitening treatment.
