Tooth fillings are used to repair cavities or damage to the teeth. They are made from a variety of materials, each with its own unique properties and advantages.
The most common filling material is amalgam, which is made from a mixture of metals including silver, tin, copper, and mercury. Amalgam is durable and long-lasting, and it’s often used for fillings in the back teeth where chewing and biting forces are strongest.
Another popular filling material is composite resin, which is made from a mixture of plastic and glass particles. Composite fillings can be matched to the color of your natural teeth, making them a popular choice for visible front teeth.
Ceramic fillings are made from porcelain or other materials and are also designed to match the color of your teeth. They are more expensive than amalgam or composite fillings, but they are also more durable and can last for many years.
Gold fillings are another option, and they are often considered the most durable and long-lasting filling material. They are also the most expensive, however, and their bright color can make them less popular for visible teeth.
Finally, glass ionomer fillings are made from a mixture of glass and acrylic. They are typically used for small fillings or for fillings in areas where the filling material may be difficult to place or keep dry.
In summary, tooth fillings can be made from a variety of materials, including amalgam, composite resin, ceramic, gold, and glass ionomer. Each type of filling material has its own unique properties and advantages, and the choice of filling material will depend on factors such as the location and size of the cavity, your budget, and your personal preferences. Your dentist can help you choose the best filling material for your needs.
