Choosing the Right Type of Dental Fillings: A Comprehensive Guide

Dental fillings are essential for restoring teeth damaged by cavities or minor cracks. With so many materials available, from traditional metals to advanced composites, it’s important to choose the one that best suits your needs. Explore different types of dental fillings to make an informed choice for a healthy and confident smile.

Ceramic Fillings

• Ceramic fillings are made from porcelain, which makes them durable and aesthetically appealing. Although more expensive than other types, ceramic fillings resist staining and abrasion better than composite fillings. 

Ceramic fillings are brittle as compared to composite fillings so they have to be used on larger cavities to prevent breakage. For this reason, the affected area of the tooth is made larger to allow enough room for the extra bulk of filling. Ceramic restorations are also referred to as inlays and onlays.

Silver Amalgam Fillings

• Silver amalgam fillings are a widely used option in dental care. Despite the name, they consist of a blend of metals, including silver, tin, zinc, copper, and mercury. These fillings are highly durable, cost-effective, and can last up to 12 years with proper care. Dentists like them for their ease of application due to their malleability.

However, silver amalgam fillings are not ideal for visible teeth because of their metallic appearance. They may also expand or contract with temperature changes, potentially causing cracks in the tooth or gaps between the filling and tooth surface. These gaps can allow bacteria and food particles to enter, leading to new cavities. While there is ongoing debate about the mercury content, silver amalgam has been deemed safe for dental use.

Composite Fillings

• Composite fillings, made from a blend of plastic and resin, are a popular choice for those looking for a more natural look. They are applied in a soft state and hardened using a curing light, allowing them to be color-matched to blend seamlessly with surrounding teeth.

While composite fillings are less clearly visible, they are not as durable as silver amalgam. Typically lasting between 5 to 10 years, they may require replacement sooner. Despite this, their aesthetic appeal and versatility make them a favored option for visible teeth.

Glass Ionomer Fillings

• Glass ionomer fillings are made from a mix of glass and acrylic. They are commonly used for children whose teeth are still changing. Glass ionomer fillings release fluoride into the tooth to prevent further decay. 

They are weaker than composite resin and last only a few years. They crack or wear out as time goes by. Unlike composite resin, they are not natural-looking and do not match the tooth color.

Gold Fillings

• Gold fillings are among the most expensive types of dental fillings, but they are less commonly used. It is usually difficult to find a dentist who uses gold fillings for dental restoration. Their durability is matchless. They can last up to 15 years without corroding. Proper fitting of a gold filling requires more than one session. 

They are strong enough to withstand chewing without damage. Some patients find gold fillings more attractive than silver amalgam fillings. However, gold cast fillings cost ten times more than other types of dental fillings.
