Teeth whitening is a widely accessible procedure offered by many dentists and even OTC by chemists. While getting rid of stained teeth for a brighter smile seems like something everyone should want, is teeth whitening safe? Given the many options for teeth whitening treatment, how safe is teeth whitening when administered by a dentist? 


The basics of teeth whitening

Teeth whitening is the process of removing discolouration from natural teeth, either by  physically removing stains from the tooth or by means of chemical whitening.  

Teeth whitening seeks to target two primary types of discolouration, intrinsic and extrinsic. Extrinsic discolouration is very common and is a result of stains on the enamel of the tooth from tobacco, tea, coffee, and other pigmented foods and drinks. Not brushing your teeth frequently enough can also contribute to extrinsic stains. 

Intrinsic stains result from damage within the tooth, which can result from tooth imperfection at birth or early trauma to the tooth, as well as medications and ageing. Teeth with intrinsic damage will often appear grey, dull, and muted without any lustre. 

If not born with intrinsic tooth damage, this type of damage based discolouration will generally be caused by trauma such as sports injuries or falls in which the tooth is forcefully contacted.  


Is teeth whitening safe?

Teeth whitening is a very safe treatment when recommended or carried out by a dental professional who follows the Dental Board of Australia guidelines on teeth whitening procedures.

A registered dental or medical practitioner will safely administer teeth whitening substances after a holistic appraisal of your teeth. They will determine whether your teeth stains are intrinsic or extrinsic and will recommend the best treatment for your unique smile. At LV Dental, your dentist will work and communicate with you, and together you can establish a comprehensive and personalised plan to brighten your smile.   

LV Dental implements a professional check-up and teeth cleaning before treatments, as well as x-rays if necessary, to ensure you get the most out of your treatment. This unrivaled care in conjunction with skilled appraisal and procedure will leave you with the gleaming white smile you deserve. 

Your dentist will advise you on how to increase the longevity of your teeth whitening procedure, as well as offer safe at-home alternatives to repeated in-office treatments. 

LV Dental recommends regular brushing and flossing, as well as maintaining a six-monthly check-up schedule to keep your smile at its best for at least a year, and possibly longer. Practicing healthy life-style choices like limiting stain-causing food and beverages and avoiding tobacco products will also keep your teeth healthy and bright. 

Over the counter versus in office teeth whitening

Is teeth whitening safe when administered through store-bought treatments? It is possible to be, but there are also other factors to be aware of. 

Having a professional analyse your teeth to determine whether blemishes are caused by intrinsic or extrinsic factors is always safer than trying to determine this for yourself. With the benefit of professional eyes, your dentist can determine precisely the level of treatment your teeth need, which eliminates the risk of potentially damaging your teeth through store bought options. 

Consulting your dentist is the best course of action when considering teeth whitening. LV Dental offers in-chair teeth whitening or take-home teeth whitening options. 


Teeth Whitening Options

If take-home teeth whitening options are for you, your dentist will prescribe whitening trays and Zoom take-home kits. However, take-home methods take longer to achieve optimal results, and the effects don’t last as long as an in-chair procedure.  

In-chair treatment uses the Philips Zoom whitening treatment, a reputable brand proven to whiten teeth. Zoom is highly effective at removing discolouration from your teeth, as well as restoring the natural white of your tooth enamel and even whitens the dentin layer of the tooth, so your teeth are up to eight shades lighter. 

During the procedure, your dentist will cover your lips and gums, completely exposing your teeth and allowing for the Zoom whitening gel to be applied. Once the gel is sufficiently applied, a Zoom light is used to activate the hydrogen peroxide, beginning the whitening process. Gel is applied for 15 minutes before removal. This is repeated three times, so the entire treatment takes about 45 minutes leaving your teeth sparkling.
