This is the process of reparing the integrity of teeth that has been damaged by cavities, abrasion, or breakages. Thanks to modern technology, composite fillings are much more durable, and are the same color as natural teeth. Composite fillings have replaced amalgam fillings because the latter is not preferred anymore due to health and aesthetic reasons. Composites bind to the teeth with bonding systems, not mechanic ones. Therefore, removing extra dental tissue is not necessary to ensure binding.
