Composite fillings are usually formed using a mixture of resins, fillers, and colorants. They are applied to the tooth in layers and “cured."
Unlike silver amalgam fillings, composites can be made to match the color of your natural teeth, giving you a more seamless-looking filling than amalgam fillings.
Since the composite bonds directly to your tooth, these fillings require less removal of healthy tooth, which leaves the remaining tooth structure more intact and stronger. They are also less susceptible to cracking and chipping due to temperature changes in your mouth than amalgam fillings.
