Saving a decayed tooth from extraction requires a dental filling. Also known as tooth fillings, they come in several forms and are applied to newly-cleaned teeth to prevent further decay and therefore preserve their structures. How long the fillings last depends on the type–learn about common options below. 

What Are Some Popular Types of Tooth Fillings? 

1. Amalgam

Silver amalgam fillings are not made entirely of the precious metal, since they also feature zinc, mercury, and copper. They remain popular for their durability and longevity, as silver fillings typically last 12 years or more. However, they are not recommended for individuals with metal allergies or those who have cosmetic concerns, since such fillings are not tooth-colored. Amalgam fillings can also expand and contract in reaction to temperature changes, creating gaps between the material and tooth that allow bacteria to collect and promote decay.

2. Ceramic

These tooth fillings are made from porcelain. They are tooth-colored for natural-looking results and known for their abrasion and stain resistance. Since ceramic fillings are relatively brittle, they work best in large cavities and are referred to as porcelain overlays and inlays. The bigger the ceramic filling, the less likely it is to break. With the right care, these tooth fillings can last up to 20 years. 

3. Glass Ionomer

Children are the usual recipients of glass ionomer fillings, as they contain fluoride that protects teeth from decay. Made of glass and acrylic materials, these tooth fillings last a few years before they need replacing. Glass ionomer fillings are more likely to crack than any other filling material. 

4. Composite 

Another natural-looking option made of plastic and resin materials, composite fillings undergo curing with a blue light to harden within the teeth cavities. They last up to 10 years and provide solutions for numerous dental issues, including worn, cracked or broken, and chipped teeth. Composite fillings can even be used to close sizable gaps between teeth.
