When the man visited the first dentist, Dr C, for investigation of the pain, he was unable to lift his tongue. The dentist took x-rays, suspected infection and prescribed antibiotics.
Twelve days after the filling was put in, the second dentist removed a dental cotton roll tucked underneath the man's left bottom molar beside his tongue.
"Mr A had a large, deep ulcer where the cotton roll had been sitting," Ms Wall says. "Having had the cotton roll removed, Mr A immediately felt better and, two days later, was feeling well."
Ms Wall says that in failing to account for the number of cotton rolls used, the dentist's care fell below the accepted standard.
"Dr C's management of Mr A's condition and concerns following treatment, including later failure to detect the retained cotton roll, was sub-optimal."
She ruled the dentist had failed to provide services with reasonable care and skill and so breached the code of patients' rights.
The dentist apologised to the man and Ms Wall asked the Dental Council to consider whether the dentist should undergo a competency review.
