If you need a dental filling, there are several materials to choose from. Here's a quick guide to help you decide: **Composite Fillings**: Made of glass or quartz in resin, these are great for small to medium cavities and areas that get a lot of chewing. They can be closely matched to your tooth color but may stain over time. **Glass Ionomers**: Made of acrylic acids and fine-glass powders, these can release fluoride to help prevent decay. They blend well with your teeth but are not suitable for heavy chewing surfaces. **Porcelain/Ceramic**: Used for crowns, inlays, and veneers, these materials match your tooth color and are very durable. However, they require multiple dentist visits and can be expensive. **Amalgam**: A mix of silver, tin, copper, and mercury, these fillings are long-lasting and cost-effective. They are visible when you smile and may cause temporary sensitivity. **Silver Fillings**: Strong and durable, these are used for crowns and bridges but do not match your tooth color. **Gold Fillings**: Made of gold and other metals, these are strong and durable but expensive and do not match your tooth color. Consult with your dentist to choose the best material for your specific needs.
