Woman 'still suffering' after harmful teeth whitening
A father and son, who sold teeth whitener with 110 times the legal limit of hydrogen peroxide, have been jailed.
Matthew and John Hargreaves admitted participating in a fraudulent business, while Jean Hargreaves admitted engaging in an unfair commercial practice.
The trio, from Knutsford, Cheshire, sold the product at the Royal Welsh Show in Builth Wells, Powys, in 2013.
The two men got 18 months in prison and Jean Hargreaves received a six month sentence, suspended for two years.
Kathleen Haigh told BBC's Fake Britain programme she was still experiencing the ill-effects of using the products, including not being able to drink hot or cold drinks.
