What is the correct designation for a non-specialist dentist who limits their practice to orthodontics?

The designation of a non-specialist dentist who limits their practice to orthodontics is accurately represented by stating that they are a general dentist whose practice is limited to orthodontics. This description clarifies that the dentist does not hold a specialist designation but focuses their professional activities within the field of orthodontics.

In the context of dental practice, the term "general dentist" indicates that this individual has the qualifications to perform various types of dental care but specifically emphasizes their concentration on orthodontics. This is important because it differentiates them from a formally recognized specialist who has completed a residency in orthodontics and is board-certified.

The other options suggest that the dentist has a specialist designation or indicates a misunderstanding of the terminology used in dental practice. For instance, referring to someone as a "specialist in orthodontics" indicates the formal recognition required to practice as a specialist, which does not apply here. Similarly, labeling the dentist simply as "orthodontist" would imply that they have completed the necessary training and certification typically needed for that specialty.
