People should have teeth whitening procedures carried out by a dental health professional, it has been argued.

Cosmetic Dentistry Guide reported teeth whitening kiosks are available across America for individuals looking to get a brighter smile on the go.

However, Dr Steven Spitz, who works as an implant specialist at SmileBoston Cosmetic and Implant Dentistry, noted many of the individuals who work in these establishments are using treatments they have not be trained to do and are using chemicals which could be potentially hazardous.

Therefore, he advised anyone wishing to have their teeth whitened to visit a qualified dentist, who will give them a higher level of care.

Meanwhile, a "free" online teeth whitening offer has been revealed to be a scam.

An offer by Extreme White which promises to send free treatments to individuals via the internet actually charged £59.99 for postage. Therefore, the Advertising Standards Authority ruled the promotion was misleading.
