Teeth Whitening Myths and Facts

Last April 2018, Dr. Vergara was interviewed on the beauty website “Beauty Heaven” regarding some common myths and facts about teeth whitening. Below is an excerpt from the article. I hope it sheds some insight into this very popular beauty trend.

When it comes to teeth whitening, there’s a lot of information out there. Everyone wants a sparkling white smile, but there is rampant debate about whether or not you need to see a dentist for professional teeth whitening.

To help us straighten out fact from fiction, we spoke to Dr Rouel Vergara DMD, Principal Dentist at New Leaf Dentists, who helped us dispel a few myths about teeth whitening.

MYTH: Teeth whitening kiosks are the same as dentists

You might have seen some teeth whitening salons and kiosks in your local shopping centre. But it’s important to note that while they do offer teeth whitening treatments, those treatments are not required to be administered by a certified dentist.

The teeth whitening industry isn’t heavily regulated, which could mean that the person who is providing your treatment might not be qualified to check for things that can affect your treatment, such as cavities. “I highly discourage treatments that are done in kiosks by non-dental providers,” says Dr Vergara.  “It’s important to put your safety first, and the best person for the job is still your dentist.”

FACT: You should see a dentist to whiten your teeth

As we’ve established, professional teeth whitening is best done by your dentist. There are a number of factors that can affect your teeth, especially considering the sensitive nature of teeth whitening.

“There are so many risks that teeth whitening procedures carry,” agrees Dr Vergara. “Sensitivity, gum irritation or even nerve damage are some of the common side effects of teeth whitening procedures. Having it done by a professional dental health provider minimises those risks.”

MYTH: Lasers and lights are the most effective way to whiten your teeth

“Clinical studies have proven that using lights does not make any difference with the overall results of the procedure,” says Dr Vergara. “The Council of European Dentists (CED) recently issued an advice to the public that lights have no proven benefit and may result in many adverse effects...When it comes to teeth whitening, it is all about chemistry and efficiency of the material being used.”

So if you’re wanting a gleaming smile minus the lasers and lights, it’s best to go for an in-office teeth whitening treatment. At 40 percent hydrogen peroxide, Opalescence Boost is the strongest chemically activated in-office product on the market and doesn’t require a light. The product is mixed by your dentist just before application to ensure fresh chemistry and good results.

FACT: Chemically-activated teeth whiteners can last longer than others

We’ve established that using lights and lasers to whiten your teeth isn’t always the way to go. When it comes to long-lasting results, Dr Vergara recommends a chemically-activated teeth whitening treatment.

“Chemically-activated or self-activated teeth whiteners are peroxide-based materials that actively break down stain molecules found on teeth, without the need to use an external source like lights or lasers,” explains Dr Vergara. “Because you don’t use light or any external source to activate the material, teeth are kept hydrated during the procedure and provides patients with a realistic, longer lasting whiter shade.”

To find your local Opalescence supplier, simply enter your postcode at and get ready to flash those pearly whites.

Dental 101: Teeth Whitening, Crowns and Veneers, Dental Implants

Everywhere you go these days, you are never short of seeing advertisements and billboards of people with perfect, shiny, white teeth! There are a myriad of products out there ranging from whitening toothpastes, boxed take-home teeth whitening kits from the pharmacy or "smile bars" in a shopping centre, to professionally supervised in-chair teeth whitening procedures from your preferred dentist.  How do you choose what the right treatment is for your teeth and for your particular needs?  IS your need purely cosmetic or does it go further than that?

To take the guessing aside, here is some background information from the Australian Dental Association on Aesthetic Dentistry.  It would be worthwhile having a read of this and then consulting a dental health professional to assess your current oral condition to find the most suitable solution for you...


Aesthetic dentistry, often incorrectly referred to as “cosmetic dentistry”, is the term used to describe treatments which change the way your teeth look. There is far more involved than simply changing the appearance of your teeth.

While a cosmetic procedure like tooth whitening is included in aesthetic dentistry, the field is mostly concerned with Orthodontic treatments which restore function such as teeth straightening, and Prosthodontics, which involves the insertion of teeth prostheses such as crowns, veneers and dental implants.

Teeth Whitening

As the name suggests, this treatment is all about lightening stained or discoloured teeth.

While you can buy over-the-counter, use-at-home toothpastes and strips, your dentist is best qualified to determine if you need teeth whitening, and can use a stronger bleach than you can at home, with greater safety and expertise.

You may be tempted to go to a shopping centre booth or a beautician to get your teeth whitened but neither are suitably qualified and could cause irreversible damage to your teeth and gums. DIY bleaching comes with all sorts of risks, and old wives tales treatments such as rubbing strawberries, lemons, or even bicarb of soda on your teeth, do a lot of damage to your teeth for no real whitening gain.

Keep in mind is that crowns, veneers and fillings don’t change colour when you have your teeth whitened.


Veneers are thin, tooth-coloured porcelain or glass/plastic layers fixed onto the front of your teeth that can be a suitable option if you have teeth with gaps, that are stained, discoloured, broken or chipped, crowded-in or crooked, oddly-shaped or badly-aligned.


If your broken or decayed tooth needs to be rebuilt, it’s likely your dentist will use a crown to do the job. Crowns are generally made from materials such as porcelain, and porcelain/metal combinations. Not only do they make your teeth look more attractive, but they also give them added strength, durability and stability.

Teeth straightening

Using corrective items like braces and plates, your dentist will line up your teeth with your jaw so you not only look better but have better use of the affected teeth. Once considered unsightly, braces, a key part of teeth straightening, are now much less noticeable than they were, in some cases being all but invisible.

Dental implants

If you’ve got lost or missing teeth, your dentist may use implants to replace them. Not only will your smile immeasurably improve but you’ll enjoy a better quality of life too. Your dentist is best placed to advise on the most suitable option for your teeth, and any decision on changing the look and function of your teeth should always start with them.
