One reason for that is the assumption that, because they contain mercury, they’re unsafe. Research has shown, however, that they’re actually safe for use in adults and children over the age of six.
Still, dentists have reasons for choosing composite fillings over amalgams. One is how they look. Amalgam fillings are dark colored and stand out while composite fillings blend in with teeth. On top of that, amalgam fillings can eventually cause a tooth to become fractured. This has to do with how amalgam fillings expand.
Often, when a filling expands it has to do with temperature—hot and cold liquids for instance. Amalgams can expand and contract far more easily than other materials, increasing the likelihood that a tooth will develop a crack or fracture. This is due, in part, to the fact that amalgams don’t form a tight seal with teeth the way composites fillings do. As a result, they expand and contract out of step with teeth, leading to cracks or breakage.
By comparison, composite fillings create a strong bond with teeth, supporting tooth structure and preventing breakage or fracturing.
