People considering teeth whitening treatment may be wise to visit a professional after trading standards officials in one part of the UK issued an alert over potentially dangerous products.
East Riding of Yorkshire Council discovered that some products being used in the area by beauticians and other healthcare practitioners contained a massive 360 times the permitted level of hydrogen peroxide.
The current legal limit is 0.1 per cent, but some tooth whitening products were made up of 36 per cent bleach, which could strip away tooth enamel and expose the sensitive dentine beneath.
East Riding council spokeswoman Jane Evison commented: "It is good news that more people are interested in taking greater care of the appearance of their teeth but whiter teeth should not be to the detriment of their health and wellbeing."
This comes after Midlands dentist Yusuf Kaderbhai warned Cosmetic Dentistry Guide that he has recently seen cases in which teenagers have used ash, baking soda and even household bleach to get whiter teeth.
