Composite fillings, also referred to as tooth-colored fillings, consist of a mixture of plastic and glass materials, while traditional fillings are typically made from a combination of metals such as mercury, silver, tin, and copper. One key difference between the two types of fillings is their appearance, with composite fillings blending in more seamlessly with natural teeth compared to traditional metal fillings. Additionally, composite fillings are often preferred for their ability to bond more effectively with teeth and for being less invasive than traditional fillings.
