By completing formal dental assistant training, professionals in this career field will be qualified to practice in a variety of clinical environments.

  • Cosmetic and orthodontic clinics – where dental assistants are involved with teeth whitening, bracing and correction, inlays/onlays, composite bonding, whitening of teeth, dental implants, cosmetic assessments, and complete reconstructions.
  • Maxillofacial surgery centers – encompass most aspects of both preventative and cosmetic dental procedures. However, maxillofacial surgeons are licensed to use general anesthesia, so procedures requiring a patient to be put to sleep during surgery can only be done by a dental surgeon.
  • Emergency dental clinics – where dental assistants work by assisting patients with dental emergencies, such as traumatic injuries or tooth infection that has caused extreme pain and facial swelling.
