Was the Amalgam Scam the last one?

As some of you may know there is a controversy between advocates of amalgam fillings if they are poisonous or not. The fact is they contain mercury and that metal is one of the most lethal known to humans. No doubt the whole idea of fillings made up of poison is considered a scam in Sweden and Norway for instance. These are illegal and dentists using them are prosecuted in a court of law. 


Ok, so I get this question at times from people: was this the last dental scam or do I know of any more? 


The plain answer is: It is not the last.


An ongoing one is this: you are made to believe that toothpaste is healthy for teeth.
Truth is: toothpaste contains abrasive made from cow hoofs that is supposed to brighten your teeth but instead cracks the enamel coatings of teeth and make them vulnerable to acid attack resulting in caries.


Another scam: you are made to believe that it is normal and necessary to pay a visit and a bill to a dentist once and even twice a year.


Truth is: with the yoghurt toothpaste replacer method you need not pay a visit for generic toothache reasons at all.
