Nice site, could do with captions to go with the pictures (highlighting gum disease etc) and check your links are still valid on a regular basis.
I think the most misunderstood part of dentistry is the "prevention" of problems, both by the Govt and lack of funding and patients when it comes to treatment.
The chinese doctors only get paid for the healthy patients they have, so every time someone gets ill they stop being paid. A similar approach to dental health might be a way forward for the NHS (but with a limit to the number of patients each dentist can have on the books).
