What are Dental Fillings?
Dental fillings are materials used to restore the function, integrity, and morphology of missing tooth structure resulting from cavities or external trauma. They are commonly used to treat dental caries (tooth decay) by filling the hollow space left after the decayed portion of the tooth is removed. Fillings can be made from various materials, including:
- Amalgam: A durable mixture of metals, including silver, mercury, tin, and copper, known for its strength and longevity.
- Composite Resin: A tooth-coloured material that provides a more natural appearance and is used for a more aesthetic result.
- Ceramic: Porcelain fillings that are durable and tooth-coloured, often used for inlays, onlays, and crowns.
- Gold: Highly durable and biocompatible, but more expensive and noticeable than other materials.
- Glass Ionomer: A material that releases fluoride and is often used for fillings in children or in areas not subjected to heavy chewing pressure.
