Do kids require different dental fillings?

Typically, composite (white) fillings and amalgam (silver) fillings are used in children's dentistry. What type of filling should your child have? 

How are pediatric dentistry fillings different? Here's everything you need to know:

How does a dental filling work?

Cavities can be filled with dental fillings and damaged teeth can be repaired with them. As a result of bacteria that build up on a tooth, the enamel (top layer of the tooth) decays, resulting in cavities. 

In the course of time, the cavity penetrates more into the tooth, forming a small hole. Dental fillings, or cavity fillings, are necessary to fill this gap. It is also necessary to clean the tooth in order to prevent further damage from occurring. 

A cavity that is not filled can lead to a serious infection and permanently damage the teeth and/or jaw bone. Early detection of cavities will make treatment easier and more effective. 

The prevention of nerve damage and painful symptoms can also be achieved by catching cavities early in their development.


Dental fillings: types and uses

In dentistry, composite resin fillings are the most common and amalgam silver fillings are the second most popular type.

Composite Fillings

These fillings are made from plastics, glass, and resin. They have a tooth-colored appearance. They are the most common type of filling we use on children. Fillings made of resin mimic the natural appearance of teeth for a less noticeable appearance than amalgam fillings.


  • The appearance of composite fillings, or white fillings, is almost indistinguishable from the surrounding teeth.
  • It is a safe and effective dental filling material for children to use.
  • The material adheres well to teeth, strengthening them and making them less likely to pop out of place.
  • The natural tooth structure is preserved to a greater extent.


  • A composite filling is more expensive than an amalgam filling.
  • Composite fillings take longer to place than amalgam fillings, which can be difficult if young children are not sedated. 

Silver Fillings (Amalgam Fillings) 

Amalgam is a metal alloy composed of silver, tin, and mercury. Amalgam fillings are strong and durable in general, but they have a noticeable appearance and can make teeth more sensitive.


  • Amalgam can be used to fill most areas of missing tooth structure, including large cavities.
  • Amalgam is tough and resistant to biting pressures.
  • Silver fillings are among the least expensive types of fillings.


  • Because amalgam is silver-colored, it is noticeable in the mouth.
  • Mercury, a toxic element to humans, accounts for approximately half of the material used in silver fillings.
  • Amalgam can expand and contract, causing cracks and potentially straining teeth over time.
