A composite filling is a type of dental filling made from a mixture of acrylic resin and fine particles of glass or other ceramic materials. These fillings are used to repair teeth that have been damaged by decay, fractures, or wear.

Composite fillings are a popular choice among patients and dentists because they can be closely matched to the color of the patient's natural teeth, making them virtually invisible. They can also be used on both front and back teeth, making them a versatile option for many types of dental repairs.
