A silver amalgam filling is used to repair a tooth that is affected by decay, cracks, fractures, etc. The decayed or affected portion of the tooth will be removed and then filled with a silver filling.
Each type of dental filling material has its own advantages and disadvantages. You and your pediatric dentist can discuss the best options for restoring your child's teeth. Amalgam fillings, along with composite (tooth colored) fillings, are the most widely used today. An amalgam filling is more commonly used in the back teeth since the color is not as aesthetic as a composite filling.
As with all dental restorations, amalgam fillings will not last forever and need to be maintained with both proper oral hygiene and diet.
