As a general principle, be wary of any practitioner who doesn't also do NHS work. The CPD and peer-review keep them on the straight and narrow.

I'm not sure about this since my dentist is a dental surgeon way above the grade of an average practitioner.

May be good advice in general but I don't think that not being part of the NHS should be seen as something negative.
