Types of Tooth Filling

Macro of a tooth with amalgam filling

If not taken care of, a tooth cavity can result in bigger problems, like tooth loss. It is always advised to get the cavity filled immediately to avoid further damage. Tooth fillings vary, in terms of the components and characteristics.

According to Advanta Dental, a dental care center in Texas, below is a list of different fillings that a Sequim dentist will perform. See their advantages and disadvantages as these will help to determine the appropriate choice to make. It also depends on the patient’s need and budget.


These are non-bonded and comprised of copper, silver, zinc, and mercury. It is the most affordable type and can last up to 10 years. They are strong and can withstand chewing impact. Since amalgam fillings do not match the teeth color, they are best for the back teeth.

Composite Resin

This is a mixture of glass and plastic particles. They are advantageous in several ways. They can last up to five years and often match with the tooth color. They also bond well to the patient’s tooth. Compared to others, they can be more expensive and are likely to shrink. This could form gaps between the filling and the tooth, if not done properly.

Cast Gold

Made of gold alloy, they are used for crowns, on-lays, and inlays. They can last longer than 15 years. Compared to all other fillings, cast gold fillings are the most durable. This is because gold is non-corrosive. However, they are quite expensive, and you will need more than one dental visit to have them fixed.

Dental fillings will go a long way to secure your teeth from further damage. When left unattended, a cavity will turn into tooth decay. With so many options to choose from, it is better to be safe than sorry.
