In South Africa, organized Dentistry has consistently opposed the establishment of clinical training for Dental Technicians to upgrade to Denturists, but have suggested that the irresponsible "Backdoor-quack" providers could be legitimized or that Oral Hygienists and Dental Therapists could be trained to make and provide dentures to address the backlog in denture services. In Australia and Canada Dental Therapists/Oral Hygienists becoming Denturists were given no exemptions for any subjects and vice versa, simply because there are no corresponding overlap in course content of these speciality courses.
