Disadvantages of AmalgamDisadvantages of Amalgam• Poor color match• Expansion• No bond to tooth structure• No early strength

Advantages of compositeAdvantages of composite• Early strength• Beautiful color match• Bonds to tooth structure

Disadvantages to compositeDisadvantages to composite• Very moisture sensitive• Post-operative sensitivity• Leakage in the proximal box• Difficult to establish proximal contact• More steps
