Different Methods of Teeth Whitening

This post is about the different methods of teeth whitening, as you’ll be surprised to know that there are quite a few. This post stems from the inquiries we’ve had regarding the actual process of teeth whitening. Most people like to do their own research before deciding if they’re going to use a certain service or not. So, we thought we’d lend a hand and go into the various methods of teeth whitening and hopefully ease a few minds out there who are still unsure about trying our method – in-office light accelerated bleaching.

Here are the various teeth whitening methods:

In-office Light Accelerated Bleaching

This is the method we use and the one we like to recommend. This process is simple and we’re with you every step of the way. We use a retractor to open your mouth, then we apply the gel (dentists can use about 12% or more hydrogen peroxide in their formulas, the legal limit for non-dentists in Australia is %6, we only use %5). The gel then reacts to our LED light which accelerates the bleaching process as the gel becomes activated and breaks down the stains on the teeth, not hurting the enamel.

In-office means you physically come in and we do the process for you. The biggest benefit of this is that we can explain everything to you and can answer any questions you have throughout the whole session. We’re also careful enough to make sure you experience as little discomfort and irritation to your teeth and gums as possible.

Internal Bleaching

This type of teeth whitening is directed more towards teeth that have internal staining of blood or other leaked fluids, mostly due to root canal procedures performed on the tooth in the past. This method is also in-office and only performed by dentists due to the intricate nature of the procedure. To put as simply as possible, a small access hole is drilled into the back of the affected tooth which then allows for the removal of the internal stains. This is then replaced with a bleaching agent and temporarily sealed, hence the term “internal bleaching”. After a few days and another visit to the dentist, the tooth should be the desired shade and the hole is permanently closed.

Home Kits

Home kits were mentioned in a previous post which you can view here. There are so many types of products included in home kits such as gels, mouthguards, whitening strips, and toothpastes. Home kits are convenient for those who don’t have time to go to the dentist or a salon, however they may not always produce the best results. Instructions can get confusing, especially if you’re doing it yourself and sometimes several treatments are required before you reach the shade you want. At Smile Labs, most clients are happy after just one session and only come back for touch-ups.

Whitening Toothpastes

Whitening toothpastes are well and good; however, they only contain a small amount of hydrogen peroxide (which is the main ingredient in most teeth whitening formulas as it is used as a bleaching agent). Many people also seem to think that the harder you brush, the cleaner your teeth will be. This is not the case and doing that with whitening toothpastes can cause tooth abrasion. This could long-term thin the enamel of our teeth. A suggestion we’d recommend is to use whitening toothpastes as maintenance after getting your teeth professionally whitened (without brushing too hard).


Not too many people may have known about natural methods before, but currently, almost everyone is health conscious and looking more at natural alternatives to everyday things, even teeth whitening. A natural method coming to light is the use of malic acid. Malic acid can be found mainly in green apples as well as strawberries, nectarines, cherries and lychees, to name a few. Malic acid can remove the surface stains on our teeth, however over-consumption of malic acid can damage the enamel of our teeth. Another suggestion is to eat these fruits in moderation to maintain a white smile without damaging our enamel.
