Dentists' workplaces are not sterile and thus - according to Dr. Daunderer - lack the essential prerequisite for carrying out successful open-bone surgery (as in tooth extractions). Only the classical operating theatre fulfills these hygienic prerequisites.

A few examples among many: a surgeon would never be allowed to enter an operating theater wearing street shoes, to sew up infected bone or to fill up a wound with toxic chemicals as is commonly done in dental practices, including during root canal treatment[2]. Neither would s/he be allowed to forgo proper postsurgery followup treatment of the surgical wound.

To prove his point, Dr. Daunderer among other things did swab tests in various dental practices.

Swabs taken from "sterile" drills and other "sterile" instruments, "clean" mouth wash cups, the dentist's chair, and the patient's arm rest without exception revealed the presence of highly pathogenic bacteria including staphylococcus aureus and many others (which - as Daunderer commented - "could fatally infect a debilitated or ill person").

Even after an "allround" sterilisation had been performed, observation of subsequent proceedings revealed glaring gaps in the dentists' "sterilisation chain" including

  • using the naked hand (or infected glove) to insert the drill bit
  • touching infected instruments
  • using the infected instruments and drill to attend to the next dental wound
  • not shielding the case holding the dental instruments with a sterile cover
  • touching the X-ray machine before or during surgery
  • wearing street shoes in the sterile area
  • touching wound tampons with the naked hand instead of wearing disposable gloves.

Additionally, Dr. Daunderer found the dangerous germs from the wound of a patient whose purulent tooth had been extracted in the 10+ patients treated thereafter - both the drills and instruments the dentist had used were still infected in spite of the (clearly insufficient) disinfection that had been carried out after the original extraction.

As part of his professional work, Dr. Daunderer analysed thousands of swabs sent in by dentists to identify the bacteria involved in a patient's jawbone (tooth root) infection. A "normal" infected tooth will only harbour a single type of germ. If more than one are found, they are either from the gums or the hands of the dentist - and results showed dentists' hands to be highly infected with skin germs.

In summary, a dentist has neither the training nor the technical equipment to extract teeth (impacted or not), to remove (invisible) pus or foreign substances such as mercury or broken-off drills from the jawbone, or to do bacteriological (swab) tests.

For those desiring a dental extraction or other work involving open-jawbone surgery, the only viable alternative - according to Dr Daunderer - would be surgery done by an experienced bone / oral surgeon in a clinical setting.


Dr. Daunderer was not the only medical doctor who levelled criticism at dentists' lack of proper surgical technique, hygiene and posttreatment. Very similar thoughts were expressed by eminent dentist Dr. Ernesto Adler[3].
