Materials that may be used in dental fillings include dental amalgam, composite resin, glass ionomers, gold, and ceramic. The cost of dental fillings ranges from around $75 to $200 per tooth ($75 to $145 for metal fillings and $150 to $200 for composite resin fillings). With dental insurance, gold fillings typically run between $10 and $50, while ceramic fillings range between $40 and $100.
Amalgam â This is a mixed filling made up of silver, tin, zinc, copper and nearly 50% mercury. Amalgam lasts about 10 years and is the least expensive dental replacement filling. The average cost for amalgam fillings is between $110 to $200 per filling. Composite resin â This filling is made of plastic and glass, lasting up to five years. It is more expensive than amalgam, but matches the color of your child's teeth. Treatment can be completed in only one visit to the dentist.
