Ever wonder what the difference is between at-home and professional teeth whitening? And more importantly, is it safe to whiten your teeth at home?

I had a chat with Gold Coast Consultant Dentist Dr. Rachel Pino, who shed some light on the subject.

Safety first

According to Dr. Pino, it’s definitely safe, as long as you follow all instructions and don’t try to cut corners.

“The most important thing is that you always buy a product that has been approved by the ACCC, follow the directions and never use too much gel, or leave it on for too long, ” she says. “It would be wise never to buy whitening kits online, too.”

“Remember though, you’re dealing with bleach, ” she warns. It’s a toxic substance and if not used correctly it can cause severe side effects, ” she warns.

Think: gum burn, gum irritation, irritation of the oesophagus and even distension of the stomach.

Dr. Pino adds, “Ensure that you never swallow the formula, and don’t overload the whitening tray. If the formula oozes out, wipe it off before it oozes onto your gums and potentially burns them.”

Have realistic expectations

At-home whitening kits will never take your teeth as white as the dentist can, so don’t expect to get brilliant pearly whites after just one application. On the other hand, in chair whitening can be achieved in less than one hour, and the results are instant.

“The dentist applies the gel and uses a light to activate it, ” explains Dr. Pino. “This method of whitening uses a stronger formula, and it only takes between 45 and 60 minutes. The results are instant. Straight away you will have the shade that you are after.”

That sounds really convenient, but it is more expensive (most treatments are between $700 and $1000, depending on your dentist and the formula used) and you will have greater sensitivity, like a zing sensation, which wears off after about three days. You also have to follow a white diet for three days afterwards, avoiding tea, coffee, red wine, curry, beetroot and anything that can potentially stain the teeth.

“Your teeth become quite porous from the bleach used and will absorb colour very quickly for a few days after treatment, ” says Dr. Pino.

On the other hand, at-home kits have a lower level of activating ingredients, so they won’t cause as much sensitivity. They are available at varying levels, too. Firstly, there is the kind that your dentist will supply.

“The dentist takes an impression of your teeth and custom makes a mouthguard, ” explains Dr. Pino. “The dentist will then supply you with the gel and you apply it over a period of ten days at home. This incurs less sensitivity.”

From there, you have your basic whitening toothpastes, which are very mild and really only keep your teeth bright. “These only contain around three per cent active ingredients, ” says Dr. Pino. They’re great for a maintenance program, so for someone who suffers really bad sensitivity.

You then have whitening strips and trays that you can find in the pharmacy or supermarket. “These do offer good results, but they will never be as strong as what the dentist can give you, ” say Dr. Pino. “I always suggest that people start off with a whitening toothpaste, especially if they are sensitive, then build up slowly to the strips and trays. If they are still not getting the result they require, they should see their dentist.”
