Fillings are materials used to fill the inside of various foods, adding flavor and texture. Common examples include the sweet fillings in pastries like apple pie or chocolate croissants, and savory fillings in dishes like tacos or stuffed peppers. They can be made from fruits, meats, cheeses, or vegetables, depending on the dish. In addition to food, the term "fillings" can also refer to dental materials used to repair cavities in teeth. These fillings, made from substances like amalgam or composite resin, help restore the tooth's shape and function, preventing further decay and discomfort.
