People seem to be hypnotised by the lure of having teeth that are whiter than an Oscars ceremony.
Studies show that over half of us are dissatisfied with the colour of our teeth.
The seemingly insatiable desire for whiter teeth is welcome news for makers of tooth whitening products, judging by the huge array of over-the-counter kits on offer.
They will certainly be cheaper than going to the dentist – at least in the short term. But they could end up being expensive in the long term, especially if they result in damage to the surface of the teeth and expensive dental procedures are needed to fix the problem.
