Time to think about leaving the cleaning to the professionals.

The Australian Dental Association warn that do-it-yourself whitening kits can lead to chemical burns and ulcers.

Studies have shown that some products actually do more harm than good and are not recommended, says the ADA.

Mikaela Chinotti, a spokesperson for the ADA and a dentist in Sydney, feels these products should be better regulated, adding, “Consumers should operate on the basis that if it sounds too good to be true it probably is.”
