What is teeth whitening?
Teeth whitening involves whitening your teeth to make them lighter. It won't make your teeth bright white, but it can lighten the existing color a few shades.
Who can do teeth whitening?
Teeth whitening is a form of dentistry and should only be performed on the dentist's prescription by a dentist or other regulated dentist, such as a dental hygienist or dental therapist.
Some beauty salons offer teeth whitening, but if you don't have a dentist, this is illegal and can put your oral health at risk.
You can also buy DIY teeth whitening kits at home, but these can also come with risks.
What happens during teeth whitening?
If you've had your teeth whitened, you will need to make several visits to the dental surgery in a few months.
To make a mouth guard, the dentist will measure your teeth and tell you how to use it with a bleaching gel. Then, using your at-home mouth guard, you apply the gel regularly for a set period of time over 2 to 4 weeks. Some whitening gels can be left on for up to 8 hours at a time, shortening the treatment time by up to 1 week.
Laser whitening, also known as power whitening, is another type of teeth whitening system a dentist can provide. A whitening product is painted on your teeth and then a light or laser is shined on them to activate the whitening. Laser whitening takes about an hour.
How about home kits and beauty salons for teeth whitening?
For teeth whitening, only go to a registered dental professional, because whitening by unqualified people, for example, in beauty salons is illegal. Home kits also carry risks.
What are the risks of home kits and salon teeth whitening?
Some home kits do not contain enough whitening products to be effective. Also, if a dentist is not doing the whitening, the supplied mouthpiece may not fit properly, so some of the bleaching gel may seep into your gums and mouth, causing blistering and sensitivity.
Teeth whitening in beauty salons performed by untrained or non-dentistically qualified personnel puts your oral health at risk and is also illegal.
