What are Dental Fillings Made Of

There are several types of materials used for dental fillings. However, we only use new-age composites and porcelains that have natural-looking aesthetics and incredible durability.

several types of filling

amalgam fillings

Quick to do and commonly carried out on the NHSAmalgam fillings are strong, durable and inexpensive. They consist of mercury and alloy powder that is packed into a prepared cavity.

composite fillings (white fillings)

Tooth-coloured fillings made up of very hard plastic and glass substance, which involves shaping soft putty-like material and then setting it with a bright blue light. Unlike amalgam fillings, composite fillings are bonded to the tooth structure making them more secure and less invasive.

glass ionomer fillings

Contains tiny glass particles combined with acrylic powder and set hard via chemical bonding. Popular in children’s dentistry since they they release fluoride helping to prevent tooth decay.

compomer fillings

Combined Glass Ionomer Cements with Composite resins incorporating both the strength and release of fluoride. Although they have slightly reduced aesthetics.


Usually a gold alloy as pure gold would be too soft and is made in a laboratory. Although not a popular option anymore, they provide strong sturdy fillings that last a long time.

These are preventative resin fillings, which are often placed with minimal or no drilling by sealing the actual fissures to prevent decay.

There also fillings such as Enhanced Composite Fillings, which are reinforced to have superior properties, so they wear less and are stronger.

They are often made in a process similar to ceramics and the treatment requires two visits and as such are called indirect Fillings.
