Dental amalgam fillings, commonly called silver fillings, have been used for many years to restore teeth damaged by cavities. Known for their strength and durability, amalgam fillings were traditionally common in back teeth where chewing forces are strongest.
Today, tooth-colored fillings are increasingly popular because they restore the tooth while blending naturally with your smile. At Dent Blanche Dental in Princeton, NJ, we focus on modern restorative solutions and evaluate each tooth individually to determine the best filling material. Dent Blanche Dental
If you already have an older amalgam filling, regular dental examinations can help determine whether it remains healthy or needs repair or replacement.
Overview
Dental amalgam is a metal-based restorative material traditionally used to repair cavities.
Often called a silver filling because of its metallic appearance, dental amalgam is strong and durable. It was especially common for restoring molars and other back teeth exposed to substantial chewing pressure.
Modern dentistry also offers tooth-colored alternatives, including composite resin and ceramic restorations.
At Dent Blanche Dental, we focus on preserving healthy tooth structure while restoring strength, function, comfort, and appearance.

What Are Dental Amalgam Fillings?
What are amalgam fillings?
A dental amalgam filling is a metal-based restoration used to replace tooth structure damaged by decay.
Because of its silver-gray appearance, a tooth amalgam filling is frequently called a silver filling.
Amalgam dentistry was particularly common for molars because these teeth experience considerable pressure during chewing.
Dent Blanche Dental’s existing restorative dentistry information describes amalgam fillings as strong and long-lasting but more noticeable than tooth-colored composite fillings.
Today, patients have several additional options for repairing cavities, including composite resin and ceramic restorations.
Benefits of Dental Amalgam Fillings
Amalgam became a widely used dental filling material because of several practical characteristics.
Long-Lasting
Amalgam fillings are known for strength and durability.
They were frequently placed in back teeth because molars experience substantial chewing forces.
However, every dental restoration can eventually wear, crack, loosen, or develop decay around its edges.
How long a filling lasts depends on:
- Size of the restoration
- Location of the tooth
- Bite forces
- Grinding or clenching
- Oral hygiene
- Diet
- Cavity risk
- Amount of healthy tooth structure remaining
Regular dental checkups allow us to monitor existing fillings and the natural teeth around them.
A Trusted Option for High Cavity Risk
Amalgam was historically a common choice for restoring cavities, particularly in areas requiring a strong restoration.
Modern restorative dentistry provides additional choices.
At Dent Blanche Dental, composite fillings are especially popular because they bond to tooth structure and can closely match the natural color of your teeth.
The Amalgam Filling Procedure
The traditional amalgam filling procedure follows the same basic goal as other cavity treatments: remove decay and restore the damaged portion of the tooth.
The procedure typically involves:
- Numbing the tooth: Local anesthesia helps keep you comfortable.
- Removing tooth decay: The damaged portion of the tooth is carefully removed.
- Preparing the cavity: The tooth is shaped to receive the restoration.
- Placing the filling: The amalgam material is placed into the prepared tooth.
- Shaping the restoration: The dentist recreates the natural shape of the tooth.
- Checking your bite: The filling is adjusted so your teeth meet comfortably.
- Finishing the restoration: The surface is smoothed and finished.
At Dent Blanche Dental, our priority is to remove decay conservatively, preserve healthy tooth structure, and restore comfortable function.
How Amalgam Fillings Compare to Other Types of Tooth Fillings
There is no single filling material that is ideal for every tooth.
Your dentist considers the size and location of the cavity, remaining tooth structure, bite pressure, cosmetic preferences, and other factors before recommending treatment.
Amalgam vs. Composite Fillings
Composite fillings use tooth-colored resin that can closely match your natural enamel.
Benefits of composite fillings include:
- Natural tooth-colored appearance
- Strong bonding to tooth structure
- Good durability for appropriate cavities
- Excellent cosmetic results
- Ability to restore front or back teeth in appropriate situations
Amalgam fillings have a metallic appearance and are therefore much more noticeable.
Dent Blanche Dental increasingly focuses on modern, natural-looking restorative materials. Our existing dental filling guidance identifies composite resin as a preferred choice when appearance and conservative restoration are priorities. Dent Blanche Dental
Amalgam vs. Glass Ionomer Fillings
Glass ionomer is another restorative material used in selected situations.
It may be appropriate for certain smaller cavities or areas where its specific properties are beneficial.
However, the appropriate material depends on the location and size of the restoration.
Amalgam vs. Ceramic Restorations
When a tooth requires more restoration than a traditional filling can predictably provide, a ceramic inlay or onlay may be considered.
An inlay fits within the cusps of a tooth, while an onlay can extend over one or more cusps.
Dent Blanche Dental offers modern CAD/CAM restorative dentistry, allowing us to create precise ceramic restorations for appropriate cases.
Should Old Amalgam Fillings Be Replaced?
Not every old silver filling needs to be replaced.
If an amalgam filling remains stable and the surrounding tooth is healthy, your dentist may simply continue monitoring it.
Replacement may be considered if the filling:
- Cracks
- Breaks
- Becomes loose
- Shows significant wear
- Develops decay around its margins
- No longer seals the tooth adequately
- Contributes to fracture or weakening of the tooth
- Requires replacement for another dental reason
The decision should be based on the condition of the individual tooth rather than the age or appearance of the restoration alone.
During your dental examination, we can evaluate existing fillings and determine whether they remain functional.
What Can Replace an Old Amalgam Filling?
When an old amalgam restoration genuinely needs replacement, the appropriate new restoration depends on how much healthy tooth remains.
Options may include:
Composite Filling
A tooth-colored composite filling may be appropriate for a small or moderate cavity.
Composite resin bonds directly to the tooth and blends naturally with surrounding enamel.
Ceramic Inlay or Onlay
A larger restoration may benefit from a ceramic inlay or onlay.
These restorations can provide additional strength while preserving more natural tooth structure than a full crown when clinically appropriate. Dent Blanche Dental offers inlays and onlays for teeth that require more support than a filling but do not necessarily require full crown coverage. Dent Blanche Dental
Dental Crown
If a tooth has lost substantial structure or has become significantly weakened, a dental crown may provide better protection.
The correct treatment depends on the condition of the tooth after the old restoration and any decay are removed.
How to Save Money on Your Dental Fillings
One of the best ways to control dental filling costs is to treat decay before it becomes extensive.
A relatively small cavity may require only a filling. As decay progresses, treatment can become more complicated and may eventually require an inlay, onlay, crown, root canal, or extraction.
Dent Blanche Dental’s current filling-cost guide notes that pricing depends on factors including the cavity size, tooth involved, filling material, and number of surfaces being restored.

Dental amalgam is a metal-based filling material traditionally used to restore teeth damaged by cavities. Because of its metallic appearance, it is commonly called a silver filling.
What are amalgam fillings?
Amalgam fillings are dental restorations used to replace tooth structure lost to decay. They were historically common in back teeth because of their strength and durability.
What is a amalgam filling?
An amalgam filling is a metal-colored dental restoration used to repair a cavity. It is also commonly known as a silver filling.
What is a tooth amalgam filling?
A tooth amalgam filling is a restoration placed in an area where decayed tooth structure has been removed. The material fills the resulting cavity and restores the tooth’s shape and function.
How long do amalgam fillings last?
Amalgam fillings are known for their durability and may function for many years. Their lifespan varies according to the size of the restoration, tooth location, bite forces, grinding or clenching, oral hygiene, and cavity risk.
Are amalgam fillings still used?
Amalgam fillings may still be encountered in dentistry, particularly in patients who received them years ago. However, modern tooth-colored materials such as composite resin are increasingly popular. Dent Blanche Dental focuses on modern restorative options that combine strength with natural-looking results.
Should I replace my old silver fillings?
Not automatically. If an existing filling is stable and the tooth remains healthy, it may simply be monitored. Replacement may be recommended when a filling becomes damaged, loose, worn, or develops decay around it.
Can cavities develop around an amalgam filling?
Yes. A filling repairs part of a tooth, but the remaining natural tooth structure can still develop decay. Regular examinations help identify problems around existing restorations.
Are composite fillings better than amalgam fillings?
The appropriate material depends on the individual tooth. Composite fillings provide an important cosmetic advantage because they can closely match natural tooth color. They also bond directly to tooth structure. Your dentist can determine which restoration is most appropriate based on cavity size, location, bite forces, and remaining tooth structure.
What happens if an amalgam filling cracks?
A cracked or loose filling should be examined. Depending on the amount of healthy tooth remaining, treatment may involve a new filling, ceramic inlay or onlay, or a dental crown.
