A report from the NHS Information Centre for health and social care (The IC) shows that the average person has anywhere between £30 and £50 spent on them depending on whereabouts they live.
Cheshire and Merseyside strategic health authority (SHA) spent the most per person in 2005/2006 at £50.
However, patients in Hampshire and the Isle of Wight had only £30 spent on them.
For England as a whole, spend on NHS dental services increased from £27 per person to £39 per person during the period.
The data refers to the period prior to the introduction in April 2006 of the new dental contract, which has come under repeated criticism for its failure to improve access to NHS dentists.
As a result, many patients have gone without visiting a dentist or sought private dental treatment.
