Mrs Carcoforo, of Wanstead, said: "Cristina was three-and-a-half when she had a horrible experience with a dentist. They said they'd have to put her to sleep and she was so frightened they had to hold her down in the chair. It left her deeply traumatised." Cristina then refused all treatment, but a friend told Mrs Carcoforo about Dr Hearsum, 43, and the Special Care Community Dental Service in Barking.
