NEW regulations on tooth whitening products containing bleach take effect from today.
Products which contain more than 6pc of hydrogen peroxide can no longer be legally sold in shops and pharmacies.
The move follows a European Council directive aimed at regulating the popular tooth whitening products.
The Irish Dental Association (IDA) said that from now on, consumers may only be sold products containing a limit of 0.1pc hydrogen peroxide.
Products containing more than 0.1pc and up to 6pc can only be administered by a dentist, or on the prescription of a dentist. Meanwhile tooth whitening will be restricted to those over 18 years of age.
Dr Tom Feeney, the IDA representative on the Council of European Dentists, said the new regulations enhance patient safety by stipulating how tooth whitening should be done.
