Everyone these days seems to want  gleaming set of pearly white teeth. Having  perfect Hollywood smile has created  multi-billion-dollar global teeth-whitening industry. However, not all is shiny and bright behind this business.  new report from  BBC states that illegal teeth-whitening beauticians are putting their customers at risk of serious health problems. These include burnt gums and lips, blisters and lost teeth.  BBC reports that  General Dental Council in the UK reported  26 per cent increase in complaints last year from people who had suffered problems after teeth-whitening procedures. In many cases,  people performing  teeth whitening were untrained and unqualified.
The teeth-whitening industry in  UK is regulated and the practice can only be performed by professionals who have registered with  General Dental Council.  BBC carried out  undercover investigation, which unearthed "thousands" of ill-qualified teeth-whitening practitioners. Two BBC researchers went undercover and paid nearly $400 each to attend  teeth-whitening course at  London beauty college.  course lasted just five hours. The researchers received  certificate of attendance and were told they could earn $100  hour to treat customers. Anyone attending these courses and setting up their own businesses would be doing so illegally and they could end up with  criminal record.
