DEFINITION OF A COSMETIC PRODUCT

Cosmetic Teeth Whitening is NOT a Health or Dental Product, Service or Procedure; the sole purpose of Cosmetic Teeth Whitening is for beautification & appearance enhancement

With modern technology Cosmetic Teeth Whitening has become a simple procedure practised globally by both Beauty Industry Aestheticians & Dentists

Teeth Whitening gel was first used to whiten teeth in 1884 and although more than 125 years have passed, there has never been a recorded case of any cosmetic strength teeth whitening gel damaging the structure of a tooth

The globally accepted legal definition of a cosmetic product is:
“Any substance or preparation intended for placing in contact with the various external part of the human body or with the teeth and mucous membranes of the oral cavity with a view exclusively or principally to cleaning them, perfuming them or protecting them in order to keep them in good condition, change their appearance or correct body odours.” (The EU Cosmetics Directive (implemented in the UK by the UK Cosmetic Products (Safety) Regulations 1996)

Extraction

“There has been avoidable confusion between cosmetic teethwhitening, which whitens the colour of a normal tooth, and tooth bleaching carried out by a dentist to restore a diseased tooth to normal. This confusion has not added to the clarity of debate at European (Union) level.”

EU SCIENTIFIC COMMITTEE REPORT

See report – Opinion on Hydrogen Peroxide in Tooth Whitening Products
(Extract)
3.3.12.2. Bleaching effects on teeth and dental restoration materials
The testing revealed no increase in bleach aggression to hard tissues associated with increased hydrogen peroxide concentrations in gels. This included assessments of bleach effects on coronal enamel and dentin, root dentin and common restoratives. Thus, bleaching at concentrations up to 16% hydrogen peroxide produced no effects on ultrastructure, surface morphology or physical properties.
