The changes include, for clients through age twenty, reducing coverage of restorative services (crowns) and reducing coverage for repairs to partial dentures; for clients age twenty-one and older, reducing coverage for endodontic treatment and oral and maxillofacial surgery; and for all clients, reducing coverage for partial dentures.
