What is teeth whitening?
Teeth whitening can be a very effective way of lightening the natural colour of your teeth without removing any of the tooth surface. It cannot make a complete colour change, but it may lighten the existing shade.
Who can whiten my teeth?
By law, only dentists, dental therapists, dental hygienists and clinical dental technicians working to the prescription of a dentist can legally perform tooth whitening.
How Long Do Whitening Effects Last?
Teeth whitening is not permanent. People who expose their teeth to foods and beverages that cause staining may see the whiteness start to fade in as little as one month. Those who avoid foods and beverages that stain may be able to wait one year or longer before another whitening treatment or touch-up is needed.
