Dental fillings are used to repair decayed, rotted, or missing teeth, such as from cavities or other oral health diseases. These fillings are usually made of tooth-colored resin, which is a material that is mixed with mineral powder to form a hard substance that can be used to repair teeth; it can also be made of metal. Their primary purpose is to restore the tooth’s original shape and function, enabling proper tooth and jaw functions. Most dental fillings are placed during a dental examination known as a dental filling appointment. Furthermore, dental fillings can be used to repair chips, cracks, and holes in teeth. Dental fillings are used to protect the tooth, restore its appearance and function, and prevent the tooth from decaying further.
