Dealing with a cavity? You’re not alone. More than 80% of Americans have at least one cavity by the time they enter their mid-30s, according to Cleveland Clinic.
It’s likely your dentist will recommend getting a tooth filling if you have a cavity. A tooth filling is a way to restore a tooth damaged by a cavity to its normal function and shape. Think of it as a way to “fill” the area of your tooth where the cavity was removed.
First, understanding what is a dental filling can help you make the right choice for your smile and your budget. At Altogether Dental, we believe everyone deserves access to quality dental care, including cosmetic options like white fillings.
With your Altogether Dental membership, you can get 15-50% off all dental procedures — unlimited usage; throughout the year. Every dental procedure is included with membership, such as: routine cleanings, fillings, X-rays, crowns, orthodontia, cosmetic procedures (whitening and veneers), braces, major dental procedures (like root canals) and so much more.
Let’s explore the different types of tooth fillings available and help you find what works best for you.
What are the different types of tooth fillings?
A tooth filling is a common dental procedure used to restore a tooth damaged by decay or a minor fracture. When a tooth develops a cavity (a small hole in the tooth), it needs to be filled to prevent further decay and restore its function and structure.
Based on a national average, Altogether Dental members save up to 61% on the cost of tooth fillings. However, not all fillings are the same — there are several types of tooth fillings to choose from.
Tooth filling materials
Tooth fillings can be made from different materials. The choice of material depends on factors like aesthetics, durability and the location of the filling. Cleveland Clinic shares more information about tooth filling materials, which are either direct or indirect. Here’s a look at how fillings are done.
Direct fillings
A direct dental filling can be completed in a single visit. Your dentist shapes and places the filling material directly into your tooth cavity, eliminating the need for temporary restorations or outside laboratory work. Here are some common choices for permanent tooth filling material:
Amalgam: A durable metal mixture containing mercury, silver, tin, zinc and copper. Known for its silver-gray appearance.
Resin composite: Matches your natural tooth color. Made from a resin base combined with fine particles of quartz, silica or glass.
Glass ionomer: A tooth-colored filling made primarily from silica glass powder.
Indirect fillings
Unlike standard fillings, indirect fillings are custom-crafted in a dental laboratory before being placed in your mouth. This typically requires two visits:
First visit: Your dentist takes impressions of your tooth.
Second visit: The custom-made filling is permanently placed.
However, if your dentist uses computer-aided design/computer-aided manufacturing (CAD/CAM) systems, they may be able to create and place your indirect filling in just one visit. Here are some common materials:
Inlays and Onlays
These are specialized types of indirect fillings, ideal for teeth with moderate damage. They’re precisely fitted to your tooth. Here are some common material options:
Gold: A golden-colored mixture of gold with other metals like silver, tin, copper or palladium.
Porcelain: A natural-looking option made from minerals including feldspar, quartz and kaolin that matches your tooth color
How long do fillings last?
Filling longevity varies based on the material chosen and how well you care for your teeth. Sensodyne says that consistent brushing, flossing and regular check-ups plays an important role in maintaining good oral health. According to Aspen Dental, which accepts Altogether Dental, these are the timeframes for each type of filling:
Amalgam (silver) fillings: Up to 15 years
Composite (plastic) fillings: Up to 7 years
Gold fillings: Up to 20 years
Glass ionomer fillings: Up to 5 years
Temporary fillings: Less than 6 months
Where can fillings be placed on teeth?
Fillings can be placed anywhere decay occurs, including: between the teeth, on chewing surfaces, near the gum line, on front teeth and tooth roots.
What do dental fillings look like?
Fillings can either blend in with your natural teeth or stand out, depending on the material:
White (composite) fillings are virtually invisible.
Amalgam fillings appear silver.
Gold fillings have a distinctive golden appearance.
Glass ionomer fillings are tooth-colored, but slightly more opaque.
White tooth fillings cost
At Altogether Dental, we believe everyone deserves a smile they’re proud to show off. That’s why we make white tooth fillings more accessible through our membership program. Keep in mind that on a national average, Altogether Dental members save up to 61% on the cost of tooth fillings.
Remember that the cost of white fillings varies depending on the size of the cavity, the location of the tooth and the number of surfaces being filled. Whatever option you choose, we’re here to help you find the perfect balance between aesthetics, durability and affordability .
