Now, because silver fillings are made of metals, every time you drink or eat something hot, they expand more than natural teeth; that can cause fractures. If the fracture line is open, then have it replaced as, if we can see it, it will be a highway for the bacteria to get inside the tooth.
However, sometimes patients can be scared by bad advice and information, such as the alleged risk of silver fillings for health. If a patient decides to replace a silver filling only because it’s made from silver, that would be a poor decision.
