10 years ago or so a little known procedure called ‘dental bleaching’ came over here from the US where it was already in regular usage. (Of course).
Basically, carbamide peroxide (or sometimes hydrogen peroxide) in a gel form was squirted into plastic ‘trays’ which were then fitted over the patient’s teeth and worn over night. After a few nights previously yellow/stained teeth would begin to look noticeably whiter, it really worked!
Brilliant! The incidence of wall to wall veneers dropped through the floor overnight. Dental bleaching was safer (for the teeth) less invasive and a fraction of the cost of dental veneers.
An unbeatable product surely?
Perhaps not. Two things challenged the superiority of this simple, cheap and effective treatment.
- Firstly (American) patients decided that they couldn’t wait a few days for the result, they wanted it instantly!
- Secondly big corporates got a wind of this and realised that if they could persuade both the public and the dentists that bleaching could be done in under an hour they would get rich (and the dentists wouldn’t do so badly either).
‘Power bleaching’ aka ‘Laser bleaching’ was born…and well publicised companies like ‘Britesmile’, and ‘Zoom’ were suddenly offering better results than with the humble bleaching tray in under an hour. These companies spent millions on advertising to dentists and the public.
