Composite filling

Composite fillings are the most common types of fillings and are used on chipped and cracked teeth and cavities.
What is it?
A composite filling is made of dimethacrylates and assorted filler-particles such as fine-grained glass, ceramic, quartz powder and silicate.
Why is it used?
A composite filling is both durable and cosmetically pleasing. When glued to a tooth, it provides an effective barrier against bacteria and also holds the tooth together.
By swapping an existing amalgam filling for a composite filling, you can help to prevent already cracked teeth from breaking; unlike glass ionomer fillings, composite filling are as tough and durable as amalgam fillings.
What are the risks?
Composite fillings carry a risk of causing pain and/or heat sensitivity after fitting. These are common problems which usually subside with time, and can only be avoided by having a cavity liner put in place before the composite filling is inserted.
