Dragon Air flight attendant Wong Yuen-mei walked into Cecilia Young Yau-yau's clinic in August 2004 wanting to fix her teeth to improve her looks. But a disciplinary inquiry of the Dental Council heard yesterday that almost one year later she had spent HK$24,000 and her teeth looked worse. Dr Young is charged with unprofessional conduct for failing to diagnose Ms Wong's condition properly, preparing an improper treatment plan and not referring her to a specialist when things went wrong. Ms Wong told the inquiry she had asked the dentist to remove bad molars rather than her pre-molars, which were in good condition, to improve her teeth. Dr Young, who represented herself at yesterday's inquiry, allegedly told her the procedure, which involved braces, would take six months. But by June 2005, with her teeth hurting and still protruding, Ms Wong said she had begun to have doubts, despite being assured by Dr Young that everything was fine. On June 11, she began visiting other dentists. 'I really hoped that all the other dentists would tell me everything was normal and I could continue with you,' she told Dr Young during cross-examination. But two of the dentists expressed concern at the treatment. Dr Young, who will give evidence tomorrow, said Ms Wong's opinion had been 'poisoned' by the other dentists. She said the six weeks when Ms Wong had been seeing other dentists could have been the reason her teeth had not improved. But orthodontist Winston Tong Tai-wing, called as an expert witness, said the procedure required between 24 and 26 months for success, not six months. Dr Tong also criticised Dr Young for not keeping substantial notes and failing to properly work out the mechanics of the procedure or refer Ms Wong to a specialist. The hearing continues.
