NEW guidelines have been issued to patients who believe they have received poor treatment from their dentist after complaints went up by almost half.

The General Dental Council has updated its "standards" to outline the care patients should receive and the procedure to follow if they are unhappy with the service.

The number of complaints received by the GDC rose by 44% from 2011 to 2012, with 2274 cases received last year. A total of 33 dental professionals were struck off the register last year, including Glasgow-based dentist Dr David Black, who had practised for up to 19 years without insurance.

The new standards contain nine principles, including clarity on costs to ensure patients are clear about how much treatment will cost, and a dentist's performance or behaviour will be measured against these if a complaint is made.
