- Composites are non-condensable.
- If restoration of composites is improperly done microleakage and recurrent caries may occur.
- Composite resins have low wear resistance as compared to metal restorations.
- The life span of composites is shorter when compared to the life span of metallic restorations.
- Composites get stained with time and can show color instability.
