Dentist Michael Zuk, author of “Confessions of a Former Cosmetic Dentist”, is a whistleblower about the dangers of some dental procedures being pushed by corporate entities that are prioritizing profits over patient safety.
There are a lot of continuing education programs for dentists, but there is also a hidden element where corporate interests will train dentists to benefit the corporation, and that can cause serious harm to patients.
Most dental seminars have an underlying corporate interest or group that is benefitting - and the dental associations have not weeded out the courses that offer voodoo science and procedures that are unnecessary - some of the procedures are so new they haven't been tested on people.
Dentists can take a weekend course and start practicing that procedure on Monday morning - with patients as guinea pigs. Dental authorities have known for decades about these dangerous procedures but have been unable to make a dent in stopping them because the underlying problem of making money is influencing the treatment dentists recommend to patients.
Michael’s "Confessions of a Former Cosmetic Former Dentist" book caused a big pushback from his dental authority. Michael’s book has been banned by the Alberta Dental Association and College and forced him to take it off the market because they felt (ironically) it was harming the integrity of the profession. The topic of the book was over treatment by cosmetic dentists and the reasons why, and it is still available on the after-market.
Forcing Michael to pull his book from the market is a prime example of how the dental association is involved in a cover up of harmful dental practices and don't want the public to know about needless procedures that can cause permanent damage.
