👉 The term "extraoral" in dentistry refers to any part of the mouth that is not associated with the teeth or tongue. This can include the lips, cheeks, gums, and tongue. The inclusion of these parts makes it difficult for dental professionals to perform certain procedures such as root canal therapy or fillings because they are not directly related to the teeth. Additionally, the extraoral area can be a source of pain or discomfort for patients who have difficulty accessing their teeth.
