Final answer:
Crowns in dental insurance fall under the category of Restorative care. They are used to repair and improve the functionality and aesthetic of damaged teeth. Categories like Preventive, Orthodontics, and Prosthodontics cover other specific types of dental work.
Step-by-step explanation:
In dental insurance, crowns are typically covered under Restorative care. Restorative care is a branch of dental treatment that deals with repairing or replacing teeth to restore function and aesthetics. This includes a variety of treatments such as fillings, crowns, bridges, and implants. Crowns are used to entirely cover or cap damaged teeth, strengthen them, and improve their appearance, shape, or alignment. They may be made of porcelain, ceramic, metal, or resin and are custom-fitted to the individual tooth.
Other categories of dental care include Preventive, which typically covers procedures like cleanings, examinations, and X-rays designed to prevent diseases; Orthodontics, focused on correcting irregularities of the teeth such as alignment and bite; and Prosthodontics, which may involve the design and fitting of dental prostheses like dentures but does not usually include crowns that are mainly restorative.
