What is teeth whitening?
Teeth whitening involves bleaching your teeth to make them lighter. Teeth whitening can’t make your teeth brilliant white, but it can lighten the existing colour by several shades.
Who can perform teeth whitening?
Teeth whitening is a form of dentistry and should only be performed by a dentist or another regulated dental professional, such as a dental hygienist or dental therapist, on the prescription of a dentist.Some beauty salons offer teeth whitening, but this is illegal if there’s no dental professional present, and it may put your oral health at risk.You can also buy DIY home teeth whitening kits but these may also carry risks.
What happens during teeth whitening at the dentist?
If you have teeth whitening you will need to make several visits to the dental surgery over a couple of months.The dentist will take an impression of your teeth to make a mouthguard and will instruct you how to use it with a bleaching gel. Then, using your mouthguard at home, you regularly apply the gel for a specified period of time over 2 to 4 weeks. Some whitening gels can be left on for up to 8 hours at a time, which shortens the treatment period to 1 week.
