Advantages of composites:
- Aesthetics — the shade/color of the composite fillings can be closely matched to the color of existing teeth. Composites are particularly well suited for use in front teeth or visible parts of teeth.
- Bonding to tooth structure — composite fillings actually chemically bond to tooth structure, providing further support.
- Versatility — in addition to use as a filling material for decay, composite fillings can also be used to repair chipped, broken, or worn teeth.
- Tooth-sparing preparation — sometimes less tooth structure needs to be removed compared with amalgam fillings when removing decay and preparing for the filling.
