There are several types of dental fillings used to restore teeth affected by decay or damage. Amalgam fillings, made from a combination of metals including silver, tin, copper, and mercury, are durable and cost-effective but have a noticeable appearance. Composite resin fillings are tooth-colored and blend in with natural teeth, making them a popular choice for visible areas. They provide good aesthetics but may not be as durable as amalgam. Ceramic or porcelain fillings are highly aesthetic and resistant to staining, making them suitable for front teeth. Glass ionomer fillings release fluoride and are often used for baby teeth or non-load-bearing areas. Gold fillings, though expensive, are long-lasting and well-tolerated by gum tissues. The choice of filling material depends on factors such as the location of the tooth, the extent of the damage, cost, and patient preferences. Your dentist can help determine the most suitable type of dental filling for your specific needs.
