Which type of dental treatment involves the extraction of teeth?

Oral surgery is the correct answer because it specifically encompasses surgical procedures that involve the treatment of diseases, injuries, or defects in the mouth, jaw, and facial structures. This field includes procedures such as tooth extractions, including those that require surgical intervention due to complexities like impacted teeth or those that are severely decayed.

Endodontics, on the other hand, focuses on the treatment of the dental pulp and the tissues surrounding the roots of a tooth, primarily dealing with root canals rather than extractions. Restorative care is concerned with restoring the function and appearance of teeth, often through fillings, crowns, and other means to repair damaged teeth, rather than removing them. Periodontics deals with the diagnosis and treatment of gum diseases and the supporting structures of teeth, which may involve surgeries that preserve teeth rather than extract them. Thus, oral surgery is the proper category for treatments that involve the extraction of teeth.
