Are we talking about NHS charges or private charges? So called private dentists (all trained by the NHS) charge pretty much what they like. NHS charges are on a scale. i.e. a check up and scale and polish is £13. Have a look online and you will be able to see the scale of various charges. Under 18 years of age or 18 years of age but still in full time education, pregnant women, nursing mothers, those in receipt of qualifying benefits, are exempt. If your under 25 or over 60 then the 'check up' and examination are free.
