As a patient, I am at the mercy of my treatment provider and his/her level of expertise.  If I have specialist needs then I want a specialist with the training and education in his/her field.  If dentistry has no standards with which to hold specialists to then I can have any dentist misrepresent themselves to me about their skill.  Today many consumers take nutritional supplements or vitamins that are not FDA approved...the supplements have not been tested as to safety and as to effectiveness.  Advertising for the supplements can include any unproven claim that the manufacturer desires to help sell their product.  Consumer beware!  If any dentist can claim a speciality training without standards and regulation then how can a consumer make an informed  choice of provider?  Consumer beware!
