The myth and truths about teeth whitening

Yellow or stained teeth can result from a number of causes – red wine, coffee and tea, poor dental hygiene, or medications. Whatever the cause, if stained teeth are something you’re self conscious about, teeth whitening may be a great solution. At Kew Dentistry, we administer the award winning Phillips Zoom! teeth whitening system, which is widely regarded as the industry leader. There are also many other teeth whitening products on the market, such as whitening strips, supermarket toothpastes, or online kits. Not to mention a plethora of at-home DIY methods using household ingredients. With so many options, it can be difficult to know what the most safe and effective method is. Below, we have myth busted some common teeth whitening misconceptions so that you can make an informed choice about which method to use.

Brushing your teeth with baking soda in order to whiten your teeth at home is one of the most common myths around teeth whitening. In fact, long term use of bicarbonate soda may erode your teeth over time, and actually result in damaging your teeth more which leads to further yellowing. We would recommend steering clear of this myth.

Oil pulling has been regarded by some as a “miracle cure”, from teeth whitening, improved skin, bad breath, to reduced headaches. While there are likely no risks associated with oil pulling, there is no clinical evidence to support teeth whitening claims.

Historically, teeth whitening has had a reputation for damaging your enamel. While the chemicals involved can cause damage if used incorrectly, a recent study found that professional dentist whitening systems do not increase the susceptibility of enamel. However, it should be noted that many retail teeth whitening products are unregulated, and pose a much higher risk of accidental tooth damage. By seeking a professional treatment with Phillips Zoom! at Kew dentistry, you are ensuring that your teeth will be whitening safely and effectively.

While professional teeth whitening can last up to years, unfortunately it isn’t permanent, and touch up treatments will be required to maintain results. This is entirely dependent on lifestyle factors such as oral hygiene and consumption of tea and coffee. Compared to over the counter teeth whitening products, professional teeth whitening like Phillips Zoom at Kew Dentistry is much more effective and powerful, meaning that touch ups will be much less frequent. This avoids possible damage to teeth from regular exposure to whitening agents.

When administered by a professional, teeth whitening is completely safe and can be tailored to different levels of tooth sensitivity experienced by the patient. However, supermarket and online teeth whitening products cannot be customised in the same way, meaning that increased sensitivity is more likely to occur.
