What do swimming pools and tooth whitening have in common?

The answer should be nothing, but a lot of beauty salons who offer tooth whitening are using Chlorine Dioxide which is better known as a pool cleaner. It can be very acidic, as in the story below, and can lead to irreversible loss of enamel and sensitivity. Under General Dental Council regulations tooth bleaching is an act of dentistry and it is illegal for anyone who is not on the Dental register to prescribe/perform. They also do not carry any indemnity insurance. If you value your teeth make sure you see a professional and that the agent is pH balanced and certainly not Chlorine Dioxide.
