Dentist's Secrets - How Does Tooth Whitening Work?
Everyone wants bright, shiny, white teeth — a Hollywood smile that dazzles everyone we share our pearly whites with. Did you know that a dentist could help you with teeth whitening? They could help you achieve that picture-perfect smile you've always dreamed of. Why are my teeth not white anymore? As we age, our teeth naturally become darker and more yellow in colour. This is because of the dentine within the centre of the teeth — as we get older, the enamel surrounding becomes thinner, allowing more of the yellow dentine to show through.
