As the government's cuts to the NHS start to bite, Sam Lister, The Times' Health Editor, investigates dentistry, going undercover to reveal how some dentists are misleading patients about their rights to NHS treatment. The programme exposes dentists who are waiting until patients are lying back in the chair before telling them they must pay hundreds of pounds for private treatment, which should be available on the NHS. Dispatches also reveals that children's teeth are being neglected under the NHS and that cost-cutting dentists are outsourcing lab work to countries like China where there are little or no checks on safety or quality.
