premise: The decision led to an exodus of dentists from the NHS into private practice . In 1990 , before the cuts , only 5 per cent of dentists ' earnings came from the private sector ; today it accounts for more than half . And as private practice has grown , so the overriding commitment of the dental profession and its governing body to the NHS has weakened . Throughout the 1990s , one could not question the fervency of the BDA 's support for the NHS , but today the emphasis appears to have changed . In her speech to the BDA 's May conference in Manchester , Sanderson enthused over the merits of private dentistry . What might have been the cuts that led to dentists ' exodus from the NHS ?
hypothesis: The cut might have been to the funding of services through the dental schools .
