I'm amazed that (so far) 50% of people blame the dental organizations. Most people probably don't know that the ADA, BDA are trade organizations with no (direct) responsibility towards public health. Obviously they are still liable under public health laws, but their main body of concern is towards their own membership.

Dentists can rightly blame their trade organisations for not protecting them from the dangers of mercury, but we the public should not expect the fox to look after the hen-house so to speak.

The real problem lies with our health authorities - the FDA in the US and the NHS in the UK. We the public have every right to demand that the very people appointed to look after our health do not poison us.
