Consumers have been warned to be careful of fraudulent teeth whitening service providers following a number of incidents in the US.
Tom Corrigan, a spokesperson for the Better Business Bureau of Central North Carolina, told the News and Record he has seen a growing number of cases in which firms have tried to rip people off in recent months.
He warned that some firms may promise ridiculously cheap prices before going on to charge patients several times the amount quoted, or could hide fine print which forces them to pay more than they expected.
Mr Corrigan said people should beware of companies that change their names and recommended using only accredited providers for teeth whitening.
“The names change but the scam goes on,” he commented.
Earlier this month, Mintel revealed that almost a third of men are concerned about having yellow teeth, which could result in an increase in demand for teeth whitening services in the UK.
