Dental fillings are materials used to restore a tooth that has been damaged due to decay, trauma, or wear. The most common types of dental fillings are amalgam and composite fillings. Amalgam fillings, also known as silver fillings, are made of a mixture of metals including silver, tin, copper, and mercury. Amalgam fillings have been used for over 150 years and are known for their durability and longevity. They are also less expensive than composite fillings. However, some people are concerned about the small amount of mercury in amalgam fillings, although the amount of mercury in a filling is considered safe by regulatory bodies. Composite fillings, also known as tooth-colored fillings, are made of a mixture of plastic and glass materials. They are often used for restoring front teeth or other visible areas of the mouth, as they can be matched to the natural color of the teeth. Composite fillings are bonded to the tooth, which makes them less likely to fall out or crack than amalgam fillings. However, they may not last as long as amalgam fillings and are typically more expensive. The process of placing a filling involves removing the decayed or damaged portion of the tooth and cleaning the area. The filling material is then placed into the prepared cavity and shaped to fit the tooth. The filling is then cured, or hardened, with a special light. The dentist will check the bite to make sure the filling is even and does not interfere with the bite. Both amalgam and composite fillings are effective at restoring damaged teeth. Your dentist can help you determine which type of filling is best for your individual needs based on the location and extent of the damage, as well as your personal preferences.
