Silver fillings, also called dental amalgam fillings, were once the standard material for treating cavities. Made from a combination of metals, primarily mercury, silver, tin, and copper, these restorations were widely used for their durability and affordability. Many adults in Portland, OR still have silver fillings placed years or even decades ago.
Over time, however, these fillings can show signs of wear, age, health concerns, and appearance. Cracks, leaks, discoloration, or structural issues may indicate that a replacement is necessary. Patients also choose to replace silver fillings for cosmetic reasons or to reduce exposure to mercury-based materials.
At Burlingame Dental Arts, our experienced dental team helps Portland residents assess the condition of their existing restorations and determine the best course of action. In this guide, we’ll explore how to spot a failing silver filling, when age becomes a concern, the health and cosmetic reasons for replacing them, and what to expect during a consultation.
Warning Signs Your Silver Fillings May Be Failing
Silver fillings may need replacement if you notice discomfort, visible damage, or changes in how the tooth feels. Over time, amalgam fillings can degrade or separate from the tooth structure, leading to new dental problems.
How do I know if my silver filling is failing?
Common warning signs of a failing silver filling include:
- Pain when chewing
- Sudden sensitivity to hot or cold
- Visible dark lines or gaps around the filling
- A feeling that the filling is loose or shifting
If you notice any of these symptoms, especially in an older filling, schedule a dental exam to prevent deeper damage or decay.
What does a cracked silver filling look like?
A cracked silver filling may show jagged edges, dark spots, or fine gray lines across the surface. These cracks may allow bacteria to enter the space between the filling and the tooth, leading to secondary decay. In some cases, the tooth itself may crack around a rigid or aging amalgam filling, especially under strong bite pressure.
Visible signs of a cracked filling may include:
- Irregular surfaces when you run your tongue over the tooth
- Dark shading near the edges of the filling
- Sensitivity or mild throbbing pain
Our Portland dental team can assess the damage and recommend prompt repair or replacement.
What happens when a silver filling leaks?
Leaking silver fillings can allow saliva and bacteria to seep underneath, potentially causing new decay. This may also lead to:
- Heightened sensitivity
- Discoloration around the filling
- A metallic or bad taste in the mouth
Leaking fillings compromise the tooth’s integrity, and early intervention is key to avoiding more extensive treatment.
What does it mean when a silver filling falls out?
A lost filling leaves your tooth vulnerable to infection, decay, and structural damage. If your filling falls out:
- Rinse your mouth gently
- Avoid chewing on that side
- Call your Portland dental office immediately
You may experience discomfort, temperature sensitivity, or sharp edges where the filling was. Visit our broken or loose fillings page for urgent care guidance or to request same-day treatment.
Age Factors That Affect Longevity
Silver fillings generally last 10 to 15 years, but age-related wear can lead to failure over time. Many patients in Portland, OR have silver fillings placed in their teens or twenties, which may now be nearing the end of their functional lifespan.
How long do silver dental fillings last?
Most silver fillings last between 10 and 15 years, depending on the patient’s oral hygiene, bite pressure, and dental habits. With excellent care, some may last 20 years or more, but even the most durable restorations will eventually break down.
Several age-related factors can shorten the lifespan of amalgam fillings, including:
- Repeated chewing cycles that wear away the surface
- Wear and tear from chewing or grinding (especially for patients with bruxism)
- Thermal expansion and contraction from hot or cold foods, which may cause gaps to form
- Recurrent decay beneath or around the filling
Older fillings also tend to lose their tight seal, making them more likely to leak or crack. If your silver fillings were placed more than 10 years ago, it may be time to have them evaluated by our dentist at Burlingame Dental Arts in Portland, OR.
Health Considerations for Older Silver Fillings
Silver fillings contain mercury, which raises health concerns for some patients, especially when the filling is cracked, leaking, or deteriorating. At Burlingame Dental Arts in Portland, OR, our dentist helps patients understand the risks and determine whether replacement is necessary based on science-backed safety guidelines.
Are silver dental fillings dangerous?
Silver fillings are generally considered safe when they are intact and functioning properly. According to long-term research and recommendations from the ADA and FDA, dental amalgam is a stable and effective restorative material for most adults.
The concern arises when a silver filling breaks down, potentially allowing trace amounts of mercury vapor to release during chewing or grinding. Still, scientific studies have shown that this exposure is typically below harmful levels for the general population.
Can silver dental fillings cause health problems?
Problems from silver fillings typically arise when they crack, leak, or separate from the tooth, not because of the mercury content alone. In those cases, bacteria can enter and cause decay, gum irritation, or secondary infections. In rare situations, a broken filling may trigger exposure concerns if mercury vapor is released during eating or grinding.
If you notice discomfort, a metallic taste, or changes in the filling’s appearance, it’s best to have it examined by a qualified provider.
Do silver dental fillings contain mercury, and should you be concerned?
Yes, traditional silver fillings contain approximately 50% elemental mercury combined with other metals. While this has raised concerns, both the ADA and FDA maintain that these fillings are safe for most patients. Still, mercury vapor can be released during chewing or grinding, especially if the filling is failing.
Patients concerned about cumulative mercury exposure or interested in mercury-free dentistry can explore modern options like composite fillings or ceramic inlays. Our Portland team offers thorough evaluations and evidence-based guidance to help you make the best decision for your health and comfort.
Aesthetic Impact of Silver vs White Fillings
White composite fillings blend seamlessly with natural tooth enamel, while silver fillings remain visibly dark. In Portland, OR, many patients choose to replace old amalgam fillings with tooth-colored alternatives to improve their smile’s appearance and boost confidence.
Should I replace silver fillings with composite for cosmetic reasons?
Yes, many patients replace silver fillings with composite ones to improve aesthetics, especially for visible teeth. Unlike silver amalgam, composite fillings match the natural shade of your teeth and are virtually undetectable when smiling or speaking.
Benefits of tooth-colored fillings include:
- No visible dark spots when laughing or speaking
- Improved confidence in personal and professional settings
- Seamless appearance with the surrounding enamel
- Mercury-free material for peace of mind
If your silver fillings are visible when you smile, or if they cause self-consciousness, our cosmetic team at Burlingame Dental Arts can help you decide if replacement is the right choice. We’ve helped countless Portland residents transition to a brighter, more natural-looking smile.

Will dental insurance cover replacing silver fillings in Portland, OR?

However, if the replacement is done purely for cosmetic reasons, coverage may not apply.
Common factors influencing insurance coverage include:
- Presence of secondary decay
- Filling failure or fracture
- Documented sensitivity or discomfort
- Replacement for esthetic reasons only (often not covered)
Our team can help you review your policy and explain dental insurance and treatment costs during your initial consultation.

FAQs About Silver Fillings
How long should a silver filling last?
Silver (amalgam) fillings typically last between 10 to 15 years, though some can remain functional for 20 years or more with excellent oral hygiene. Over time, fillings may crack, wear down, or separate from the tooth structure. If you’re wondering how long a silver filling should last, our team in Portland can evaluate your specific case during a dental exam.
Is it better to remove silver fillings?
It depends on the condition of the filling. If the filling is old, leaking, cracked, or causing sensitivity, removal and replacement may prevent future decay or discomfort. Patients with aesthetic concerns or metal sensitivities may also opt to replace amalgam. Always consult a qualified provider to determine if it is better to remove silver fillings based on your oral health and risk factors.
Can old silver fillings cause bad breath?
Yes, leaking or damaged silver fillings can trap bacteria and contribute to bad breath. If decay forms under or around the filling, it can release odor and irritate gum tissue. A dental exam can confirm if a restoration is the source of the issue.
Should I replace my silver filling with white fillings?
