Final answer:
A dental assistant might be trained by a dentist instead of through a formal educational program, involving on-the-job training. Professional development and understanding the certification process can be beneficial for career advancement in the dental field.
Step-by-step explanation:
The dental professional who might be trained by a dentist instead of through a formal educational program is typically a dental assistant. Dental assistants can learn through on-the-job training provided by dentists, and this type of training can vary based on the dental office's requirements and the tasks the dental assistant is expected to perform. Some dental assistants may also pursue certification or formal education, but it is not always a prerequisite for the position.
Exploring professional development options is important in the dental field, and understanding the certification process for a particular field can help dental professionals advance in their careers. While not necessarily required for dental assistants, certification can provide additional opportunities and recognition of expertise.
