At Home Teeth Whitening: Does it Work? Dentist reveals all
Bright pearly whites might look healthy but beneath the sparking smile may lie an ugly truth. Over the last few years, we’ve seen drastic increase in at-home teeth whitening kits available which could be causing untold damage to thousands of Australians., with people excessively bleaching their teeth in a quest for the perfect smile.
The Australian Dentist Association’s 2019 consumer survey of 25,000 Australians found 22 percent had whitened their teeth – a significant eight percent increase since 20171. With more Australians trying different ways to achieve a dazzling, whiter smile than ever before, it’s important to understand the potential risks associated with cheaper and readily available whitening methods. Acclaimed dentist, Dr Minoo Ghamari, from Gorgeous Smiles Dental breaks down what everyone needs to know about the latest whitening craze hitting the beauty consumer market.
- Improper application
Dr Minoo shares that one of the main concerns with at-home teeth whitening kits is the potential for improper application. Many kits available on the market provide generic trays or strips that may not fit correctly, leading to uneven distribution of whitening agents. Dr Ghamari shares that this can cause inconsistent results, with some teeth becoming more bleached than others, leaving patchy smiles. The Melbourne dentist also warns that improper application can increase the risk of the whitening agent coming into contact with the gums, causing intense irritation and sensitivity.
- Higher Risk of Tooth Sensitivity
The whitening agents used in at-home whitening products typically contain hydrogen peroxide or carbamide peroxide2. While these agents are effective at removing stains, Dr Minoo stresses that they can also cause tooth sensitivity as the bleaching agents can dehydrate the teeth.
The Melbourne dentist stressesthat prolonged or improper use of at-home kits can lead to heightened tooth sensitivity, making it uncomfortable to consume hot or cold foods and beverages. In particular, the acclaimed dentist cautions Australians with pre-existing tooth sensitivity to avoid at-home teeth whitening as it may cause even greater discomfort and exacerbate the issue.
- Limited Effectiveness on Intrinsic Stains
Use of at-home teeth whitening kits are primarily designed to address surface stains caused by external factors like caffeine, carbonated drinks, or smoking. Dr Minoo shares that the quick-fix solution may not be as effective in treating intrinsic stains that originate from within the tooth structure, such as those caused by medications or certain medical conditions. The Principal Dentist at Gorgeous Smiles reveals that intrinsic stains often require professional dental treatments that can target deeper layers of the tooth for significant results.
- Lack of Professional Experience
Unlike professional dental treatments, at-home teeth whitening kits that can be readily purchased at supermarkets lack the guidance and expertise of a professional dentist. Dr Minoo reveals that like herself, trained dentists have the knowledge and experience to evaluate your oral health, identify potential risks and recommend appropriate treatments based on your specific needs. The Melbourne dentist adds that only a professional can tailor the treatment to minimise the potential side effects and ensure the best outcome. Without professional supervision, many Australians may unknowingly be worsening existing dental issues or overlooking underlying problems that require medical attention such as gum disease, chipped teeth or cavities.
Instead of applying harmful bleaching agents to your teeth, Dr Minoo recommends booking an appointment at Gorgeous Smiles Dental in Melbourne for a consultation and tailored Phillips Zoom Whitening Treatment. Gorgeous Smiles Dental can even prepare professional teeth whitening gel for you to take home and administer in the comfort of your own home.
