More and more people are paying for brighter, whiter teeth. But does teeth whitening work and is it safe? Here are the answers to common questions about the treatment.
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.
