Orthodontist assistants help provide patient care and treatment to correct dental problems and straighten teeth. As an orthodontist assistant, your job duties include taking impressions of patients’ teeth, taking X-rays, checking orthodontic gear like braces and retainers, preparing tools for the orthodontist, and getting patients ready for orthodontic procedures. You must also update patient charts and organize the orthodontist office. You need good interpersonal communication skills to explain procedures and educate patients as well as to collaborate with your supervising orthodontist during routine and emergency procedures.
