Teeth whitening is a common dental procedure sought after by many who are looking to brighten their smiles. While gleaming white teeth automatically sounds like a good idea, is teeth whitening safe? And how safe is teeth whitening when performed by a dental professional? Are some options for teeth whitening treatments safer than others?


How does teeth whitening work?

The process of teeth whitening involves a chemical application to remove discolouration and stains from the teeth.

Teeth whitening will work toward removing two types of discolouration, intrinsic and extrinsic. The difference between intrinsic and extrinsic is that extrinsic stains are blemishes on the enamel, or outside of the tooth, while intrinsic stains are caused by trauma to the inner tooth.

Extrinsic stains generally appear as yellow or brown areas or general yellowing across the entire tooth. Intrinsic stains cause a tooth to lose its natural sheen and take on a muted grey color.

There are many causes for discolouration of the teeth. Extrinsic stains result from lifestyle choices, such as smoking, drinking coffee, or consuming pigmented food like berries. Poor dental hygiene is another huge factor in the development of extrinsic stains on the surface of teeth.

Intrinsic tooth discolouration is caused by a variety of factors, such as disease, genetics, or ageing. Intrinsic damage can also result from blunt trauma to the tooth, such as a sports injury or fall.

Teeth whitening and safety

It is common to ask “is teeth whitening safe?”. When performed by a licensed dentist who adheres to the Dental Board of Australia guidelines, teeth whitening treatments are very safe.

A dental practitioner who is experienced in performing teeth whitening procedures can provide a thorough examination of the state of your teeth, and then come up with an appropriate teeth whitening treatment plan in response.

Teeth whitening and safety

At MyHM Dentist Kellyville, an accomplished cosmetic dentist will first assess your teeth to make sure your teeth are eligible for teeth whitening treatment, assuring that safety comes first. Kellyville dentist Dr. Matsuoka then performs the teeth whitening procedure, resulting in a brighter smile and a boost in your self-confidence.

MyHM Dentist Kellyville ensures patients are knowledgeable and comfortable with their teeth whitening procedure. MyHM Dentist Kellyville also offers at-home whitening alternatives recommended by dental professionals. To keep your teeth healthy and whiter for longer periods, your dentist will also discuss the importance of teeth hygiene after your procedure and recommend that regular brushing and flossing are observed.


What about store-bought teeth whitening treatments?

If the question “is teeth whitening safe?” is important to you, then you should consider the risks presented by self-application of over-the-counter treatment methods.

It can be challenging to determine exactly what your teeth need without help. A dentist can assess whether your teeth have intrinsic or extrinsic staining and can evaluate your oral health before formulating a specific treatment plan.

When using treatments purchased from a store or a chemist, you run the risk of damaging your teeth or causing unnecessary discomfort, simply because you may not know the exact kind of treatment necessary for your unique smile.

Consult your dentist before choosing teeth whitening treatments. MyHM Dentist Kellyville provides in office treatment, as well as take home options so you can whiten your teeth at your convenience.


Teeth whitening methods

If you would prefer to have your treatment in the comfort of your home, your dentist can provide a take-home Pola night and day whitening gel kit. You will still need to schedule an appointment with your Kellyville dentist to take an impression of your teeth in order to fabricate specialised whitening trays to fit your teeth.

After that, simply put the whitening gel in the tray and wear it on your teeth overnight. You will wake up to a brighter smile. Alternatively, wear it during the day for a specified period. The duration depends on the gel formula you are prescribed.

If in-chair treatment is for you, Kellyville uses the professional vetted Philips Zoom teeth whitening system that can whiten your teeth up to 8 shades brighter in one hour. Your dentist will precisely apply the gel and use an activating light to begin the chemical process which is repeated 3 times for 15 minutes each. Once the gel is washed off, you will experience immediate results.
