Cavities Q & A

What is the purpose of a filling?

The purpose of a dental filling is to restore a tooth which has been damaged by decay. Bad cases of decay can result in a cavity, a defect left in teeth when the softening of the enamel occurs over time. You may have a cavity if you notice any of the following:

  • Prolonged toothache
  • Heightened tooth sensitivity
  • Pits or holes in your teeth

Fillings help treat cavities and restore your tooth to its normal function and shape. They can also prevent additional decay.

How is a filling applied?

Prior to the applying a filling, Dr. DeRose or Dr. Barnes first remove any decay and clean away any affected tooth material with special dental tools. After the cavity has been cleaned out, your DeRose dentist fills the cavity space and then seals it back up with one of the available filling materials in a simple procedure.

What are the different types of tooth filling materials?

The most common types of tooth filling materials are composite resins, porcelain, and gold. Dr. DeRose and Dr. Barnes help make recommendations as to which tooth filling is best for you. Their suggestions depend on a variety of factors, including:

  • The degree of damage to the tooth
  • If you’re allergic to specific substances
  • Location of the cavity
  • Cost of the material

How do the different filling materials compare?

Each material — composite resin, amalgam, and porcelain — has different advantages:

Composite resins

These fillings can be made to match the shade of your natural teeth and are used in situations when natural appearance is important, especially on front teeth. Composites might not be best for large fillings since they can chip and wear after a while.

Composite resins are more likely to stain and typically last around 3-10 years.

Amalgam fillings

Amalgam fillings are made from a mixture of metals, like liquid mercury and a powder alloy composed of silver, tin, and copper. These fillings have a silver appearance. These are the least costly types of fillings and extremely durable.


Also known as inlays or onlays, porcelain fillings are custom-made and bonded to your teeth. These can be color-matched, similar to composite resins — however, porcelain is better at repelling stains.
