Are composite fillings better than silver amalgam fillings?

Composite fillings bond directly to your tooth, which results in the removal of less healthy tooth structure. Amalgam fillings require additional sculpting of the tooth to provide anchors for the solid amalgam. Composite fillings are not as hard and inflexible as amalgam fillings, which means stresses caused from biting and chewing can be distributed more naturally and reduce the risk of your tooth cracking.
