The most common treatment in dentistry is dental filling. Dental filling is a treatment method used to repair teeth that have lost their integrity due to caries or trauma. There are many materials and methods used for dental filling. Mainly used materials are composites, amalgam, porcelain, glass ionomer and compomers.
Types of dental fillings
Composite filling: Composite fillings are tooth-colored fillings and are the most preferred materials due to their cost and ease of application. Advanced composites have no known side effects and have no harmful effects on general health. The average life of composite fillings is 4-7 years.
Amalgam fillings: amalgam fillings or metal fillings are obtained from a combination of mercury, copper, lead and other metals, amalgams contain approximately 50% mercury in their structure. Metal fillings have a history of 100 years in dentistry. Perhaps the most durable type of filling is amalgam, which can stay in the mouth for 10 years and protect against tooth decay. However, amalgams have many disadvantages and have negative effects on general health. Its use is not recommended today.
Porcelain fillings: The preferred material in large cavities is porcelain. After the caries is cleaned, an impression is taken from the tooth and porcelain fillings are produced in the laboratory and then adhered to the tooth with special adhesives. Porcelain fillings are resistant to breakage and are the best option for repairing teeth in cases of major tissue loss.
