Fillings Q&A

What are fillings?

Fillings are restorative treatments for cavities and tooth decay. Cavities create small holes in your teeth that can grow without treatment. As decay penetrates the deeper layers of your tooth, it damages the protective tooth enamel. It can even travel to the center of your tooth, leading to pain and discomfort.

Over time, cavities can cause enough damage to permanently loosen your teeth. If decay progresses, your permanent teeth may even require extraction.

Fillings literally fill in the holes left behind by cavities to restore your tooth function. They also protect decayed teeth against further damage. If you have cracked, chipped, or worn teeth, a filling can help restore its shape and size.

Are there different types of fillings?

There are many different types of fillings, but the most popular options include:

Amalgam (silver) fillings

An amalgam filling is a traditional metal restoration. These fillings are silver in appearance and very durable, so they function best in your back molars. Amalgam fillings are long-lasting and affordable, but they aren’t as aesthetically pleasing as some other options.

Composite fillings

Composite fillings match the natural shade of your teeth. These tooth-colored fillings are aesthetically pleasing, but not as durable as amalgam fillings. As a result, they work well in the front of your mouth, which others can see when you smile. Your bite isn’t as strong near your front teeth, which can extend the life of tooth-colored fillings.

How do dentists place fillings?

How Dr. Casey places your filling depends on the type you choose. With special training through the American Academy of Cosmetic Dentistry, she pays close attention to even the smallest details. Dr. Casey treats your fillings like functional art, creating restorations that are strong and beautiful.

The first step in the filling process is removing any decay from your affected tooth. Once the area is clean and free of decay, she can place your filling.

For amalgam fillings, Dr. Casey mixes a powder and liquid solution to form a putty. She then uses the mixture to fill your cavity. The mixture hardens and seals the cavity to protect your tooth from damage.

Applying a composite filling is a more complex process. Composite resin is a liquid material that requires a curing light to harden. Dr. Casey applies a thin layer to your tooth and hardens it with a curing light. She repeats the process until the size and shape of your tooth is restored.
