We spoke to Sydney Dentist Dr Luke Cronin about the 5 most common teeth whitening myths.
1. Whitening is bad for your teeth
Teeth whitening is the least invasive, safest and cost-effective way to improve the appearance of your smile. However not all whitening products are created equal and it’s important to follow the instructions of the specific product. Over the counter whitening products contain a lower concentration of the whitening agent than professional products. The over-use of these products to achieve that Instagram white shade is where you can do serious damage your enamel.
2. Quit coffee to get pearly whites?
The good news is you don’t have to give up your daily brew if you want to have your teeth whitened or use whitening products. Over time the regular consumption of coffee or tea will stain the tooth’s external layer. A regular clean at the dentist will remove this type of staining, however stubborn stains will dissolve with whitening treatment. To maintain your brightness post-whitening regular brushing is key.
3. I can’t whiten my teeth because they are sensitive
The minor temporary sensitivity you may experience when getting your teeth whitened is different to sensitivity from hot and cold. Sensitivity can be caused by a number of teeth issues, so it is important consult your dentist to determine the cause. The good news is that sensitivity can be reduced with de-sensitising products applied prior to and post-whitening.
4. My teeth are different colours so whitening won’t work
Every tooth colour is unique thanks to the thickness and translucency of the tooth’s enamel and the internal composition of the tooth. It’s completely normal to have colour differences across your smile and shouldn’t hold you back from getting your teeth whitened. Teeth whitening will lighten both the yellow or darker internal dentine and any staining or discolouration on the external enamel. Whitening can actually create greater uniformity in colour by lightening the tooth’s colour and removing staining.
5. I have fillings so I can’t get my teeth whitened
Thankfully this isn’t the case. Your fillings won’t be affected by whitening agents or magically change colour with a treatment. If you want to create a seamless white smile you can have your existing fillings replaced with white fillings.
