What Type of Dental Filling Is Right for Me?

As the name suggests, dental fillings are used to fill an area of a tooth that has been removed due to decay. When treated for a cavity, a dentist will isolate the tooth area that has decayed and remove it. This leaves a portion of the tooth vulnerable to even further decay. A dental filling is then added to protect the area from future damage. Yet, there are several different types of dental fillings used by dentists. Knowing the benefits of the different kinds of fillings is vital to understanding which one is best for you. Currently, the materials used for dental fillings include composite resin, silver amalgam, gold, ceramic, and glass ionomer.

Here is an in-depth look at the different types of dental fillings currently available:
 

Composite Resin Fillings

As far as aesthetics are concerned, composite resin fillings can be very closely matched to the natural color of the surrounding teeth, making them an ideal choice for dental procedures involving visible teeth. Composite resin fillings also bond exceptionally well to the tooth's structure, providing superior support during eating and other activities involving the mouth. Composite resin can also be utilized to repair cracks and chips. In addition to composite resin fillings' versatility, it also requires the minimal removal of tooth structure compared to other types of dental fillings.
 

Glass Ionomer

Glass ionomer fillings consist of both acrylic and glass, which bond to create this unique ionomer. This material is used explicitly for fillings below the gum line and in small children. Drilling is still required for this material, yet glass ionomer fillings can release fluoride in the tooth area they cover, offering additional protection against future decay. This material is considerably weaker than other alternative filling materials and has an average lifespan of fewer than five years. New advancements in this material’s design are leading to a longer lifespan and increased durability.
