Does in-chair teeth whitening work? And is it really better than at-home whitening kits?



Does professional teeth whitening work?

From personal experience, I can say it absolutely does. I walked in to the Countouring Bodies clinic in Sydney with dull, slightly yellow teeth stained by one too many cups of coffee and wanted a smile more like Zoey Deutch, who has a perfect set of pearly whites. I walked out with teeth 14 shades brighter after just one session.

The treatment itself was pretty non-invasive; all I had to do was sit back and chill out with some gel in my mouth for an hour.

First beauty therapist Mary explained the treatment to me, including how long it would take and how I’d need to look after my teeth in the hours after they were whitened. Then she covered my lips in vaseline and popped a retractor in my mouth to hold my lips back during the treatment. She applied some protective salve to my gums, then covered my front teeth with a bleaching gel and popped a UV light on them to activate the bleach.

Then I just had to sit back and relax for an hour, with Mary removing and reapplying the bleaching agent every 20 minutes. Each time she checked the color of my teeth and how they were reacting to the treatment, just to make sure everything was going smoothly.

After the hour was up and the bleach had been applied and removed three times, I rinsed out my mouth and finally caught sight of my pearly whites – and god, were they white. I also noticed there were a bunch of little white spots and streaks on my teeth, but Mary assured me they were nothing to worry about – it was just decalcification, and it’s very common.

“The decalcified enamel whitens quicker than the rest of the tooth, so those spots will be more pronounced immediately post treatment and sometimes up to a day or two after,” she explained. “But after that the whole tooth itself becomes lighter and those spots blend with the rest of the tooth.”

A few days later I saw that for myself when my teeth were looking perfectly even and white – and totally worth the $100 that I paid for the treatment, which was a sale price.

How does professional teeth whitening work?

Teeth whitening essentially involves bleaching your teeth using hydrogen peroxide in different concentrations; dentists can use mugh higher concentrations than clinics like the one I went to, but also tend to charge much more. Some celebrities have had their teeth whitened by dentists, but many thank beauty clinics for their pearly whites.

In Australia, dentists are the only practitioners allowed to use products that release more than 6 per cent hydrogen peroxide, so if you have extreme staining it you may get more effective results from a dentist.

My treatment involved using the Hollywood Whitening machine and gel, which comes from the internationally renowned brand with offices in Europe, Asia and North America, but different clinics will use different products and equipment.

There are a whole range of different treatments available from different clinics and dental practitioners, so make sure to research what will work best for you. It’s always good to chat with your dentist before undergoing any dental treatment like teeth whitening, especially if you have sensitive teeth or specific dental concerns.



Is it more effective than teeth whitening at home?

Getting your teeth whitened at a clinic or by a dentist will always be more effective than at-home products, and probably safer too.

Over-the-counter whitening products have lower levels of hydrogen peroxide, meaning the effects of the treatments won’t be as noticable or significant from a single treatment. Applying these products at home also presents risks of you using them incorrectly, which can cause damage to your teeth and gums.

Research has also shown that at-home whitening products are more likely to damage the enamel on your teeth over time, which can cause weakness and sensitivity. These products can also burn your gums if applied incorrectly, and the effects often don’t last as long as professional treatments.

Speaking from experience, I tried all sorts of home teeth whitening products, from the blue light kits with mouth moulds, to whitening pens and every whitening toothpaste under the sun – and none of them ever got close to the effects of one 60 minute professional session.

Does professional teeth whitening hurt?

The process shouldn’t hurt, but you can experience some sensitivity or discomfort during treatment. The bleaching gel can cause tooth sensitivity, however this fades during the treatment, and the mouth retractor can leave your lips and cheeks feeling sore after a while. After the treatment, you may experience tooth sensitivity for hours or days, but this also fades with time.

I personally didn’t experience any discomfort during the treatment, but my teeth were sensitive for about 12 hours after and my lips were a little chapped and sore for the following days.

Does professional teeth whitening damage your teeth?

Regardless of how or where you whiten your teeth, there is always a chance your gums will be sensitive to the chemicals used and may react. Hydrogen peroxide can also cause damage and sensitivity to your teeth when applied incorrectly or too often, however professionals work to mitigate the risk of damage.

Always make sure to speak about possible risks with your dentist or practitioner before undergoing any kind of cosmetic treatment, including teeth whitening.

How much does professional teeth whitening cost?

Costs vary from hundreds to thousands of dollars depending on the treatment, and it’s often more expensive to have your teeth whitened by a dentist than by another practitioner. Speak to your dentist or local clinics to find the pricing that best suits your budget.
