Fillings

Fillings are the most common way to restore a tooth with minor decay, but they can also repair a broken or worn-down tooth. Fillings stop bacteria entering the tooth and therefore prevent cavities.

Types of Fillings

Fillings are made from several types of materials, each with its own benefits and disadvantages:
– Gold. The most expensive type of fillings, these usually last for more than 15 years.
– Amalgam. Another long-lasting option, the main downsides are that your dentist will need to remove more of the healthy tooth to make space for the filling.
– Composites. A popular choice as the material can be matched to the color of your teeth, bear in mind composite fillings wear out faster — sometimes after just five years.
– Ceramics. Stain-resistant, ceramic fillings match the color of your teeth. These are the longest-lasting types of fillings, but they can cost almost as much as gold.
– Composite resin. This is another option that will appear the same color as your teeth, but they may stain over time. A good choice for small fillings.

The Procedure

To fit your filling, your dentist will begin by numbing the area around the impacted tooth with a local anesthetic. Then, he or she will clean a space for the filling, removing all the decay. Your dentist will apply the filling material to the space left behind, restoring the strength and structure of the tooth. Finally, you will perform a bite check to ensure that, when you close your mouth, your teeth have the correct alignment.
