The costs of laser teeth whitening and other treatments has been discussed.Laser teeth whitening treatments differ greatly in cost depending on where people have the treatment carried out, but the results can often be worth the cost, it has been claimed. 
WorlDental reported that while laser teeth whitening treatments are on the whole more expensive than take-home teeth whitening kits, the improvement in results is often worth the extra expense.
The publication noted it can cost up to $600 (£400) per laser teeth whitening session at some surgeries in the US, while take-home kits normally cost anywhere between $20 and $50.
Elsewhere, in a new book entitled We Won the Lottery by Danny Buckland, the unusual stories of what some winners spent their millions on have been revealed – with teeth whitening one of the top choices.
The author claimed one winner paid for all his friends and family to have their teeth whitened.
