A filling is one method to restore a tooth which has been damaged by decay. The objective of the filling is to remove the damaged part and replace it with an artificial material, to strengthen the tooth and prevent further decay. For natural looking fillings, a composite resin (white) filling is generally the best choice.
Modern material science has created a number of fantastic composite materials which can be used to repair teeth. Material choice can depend on:
Composite fillings are color matched to your natural teeth, and create a good cosmetic appearance. The composite resin is mixed and placed in the dental cavity in thin layers where it hardens with UV light.Advantages:
Glass Ionomer fillings are color matched to your natural teeth, and create a good cosmetic appearance. They are not very strong and should only be used in placed without much biting force. They are made of acrylic and a fluoroaluminosilicate glass and generally set without UV light.Advantages:
Resin-modified or hybrid composite glass ionomer fillings are much stronger and can offer better color matching. These special materials are typically cured with UV light.
