Which material is not typically associated with fillings in dental care?

Cotton wool is not typically associated with dental fillings because it is primarily used for other purposes within the dental practice, such as maintaining a dry operating field, absorbing fluids, or providing comfort to the patient during procedures. In contrast, materials like gold, porcelain, and amalgam are specifically designed and used for restorative dental procedures to fill cavities and restore the function and aesthetics of teeth. Gold is known for its durability and biocompatibility, porcelain is favored for its natural appearance, and amalgam is chosen for its strength and resistance to wear in posterior teeth. Each of these materials serves a distinct purpose in the realm of dental restorations, while cotton wool does not fulfill a role in filling cavities.
