People seeking teeth whitening services have been warned of the health risks associated with visiting providers who have not been given suitable training.

Angela Pierce, president of the SA Dental Association, said individuals who try to save money by not using a qualified dentist may suffer from teeth damage, the Herald Sun reports.

"We're seeing more and more people come in with more problems with industrial use of teeth bleachers," she remarked, adding that cheap prices will generally indicate that a "bargain basement service" is being provided.

Ms Pierce made the comments after Felecia Williams, a customer at a beauty treatment salon in Adelaide, said she felt "instant pain" when she was given a teeth whitening treatment by an untrained beautician and was left unable to brush her teeth for a month.

Spokesman for the British Dental Association Stuart Johnston recently told the Guardian that teeth whitening procedures need to be carried out by a dentist in order to guarantee safety.
