Silver Metal Fillings
What Are Silver Metal Fillings?
Silver metal fillings (commonly known as dental amalgam) are an inexpensive and highly durable material commonly used for filling tooth cavities. Amalgam is a combination of metals that has been the most popular and effective filling material used in dentistry for the last 150 years. Amalgam actually consists of a combination of metals. These include silver, mercury, tin and copper. Small amounts of zinc, indium or palladium also may be used.
Tooth-colored white filling materials now can be used to restore teeth. Therefore amalgam is used less often than in the past. However, the newer materials can’t be used for all situations. Amalgam is less costly than other materials. It also holds up better over time, especially in teeth that undergo a lot of pressure and wear from chewing like the back molar teeth.
Do Some People Have Reactions To Amalgam?
In rare cases, people have allergic reactions to the mercury in amalgam. In order for you to find out whether you have an allergy to mercury, you will require an allergy test from your medical doctor. People allergic to mercury can receive other filling materials instead of using dental amalgam, such as white composite fillings.
Are There Alternatives To Silver Metal Fillings?
Dentists now commonly use other materials to restore teeth. These include composite resin (white fillings), porcelain and gold. Amalgam is stronger than composite resin and requires less time in the dentist’s chair. Composite resin is a tooth-colored material. Because it wears faster than amalgam, composite resin can’t be used in every situation. Porcelain and gold are also very strong materials, but they are more costly to place.
Should I Have My Amalgam Fillings Removed?
In general, you should replace amalgam fillings only when they are worn, broken or when there is decay beneath the filling. There is no evidence that dental amalgams can cause a problem. Removing good amalgam fillings results in unnecessary loss of healthy parts of the tooth and can release more mercury.

Frequently Asked Questions
1. What are silver metal fillings?
Silver metal fillings, also known as dental amalgam, are a durable material used to restore teeth affected by decay. They are made from a mix of metals including silver, tin, copper, and small amounts of mercury. They have been used in dentistry for many years due to their strength and reliability.
2. Why are silver fillings still used today?
Silver fillings are strong and long-lasting, especially in back teeth that handle heavy chewing pressure. They are often more cost-effective compared to some alternative materials. In certain situations, they may still be the most suitable option for restoring a tooth.
3. Are silver fillings safe?
Yes, silver amalgam fillings have been widely used and studied for decades. They are considered safe for most patients, although some people may have rare allergic reactions. If you have concerns, your dentist can discuss alternative materials with you.
4. What are the alternatives to silver fillings?
Alternatives include tooth-coloured composite (white fillings), porcelain, and gold restorations. These options may be more aesthetic, but they can vary in durability and cost. Your dentist will recommend the best option based on the tooth and its location.
5. Do silver fillings look noticeable?
Yes, they are more visible than tooth-coloured fillings due to their dark metallic appearance. For this reason, they are less commonly used in visible front teeth. Many patients choose white fillings for a more natural look in those areas.
6. Should I replace my silver fillings with white fillings?
In most cases, replacement is only recommended if the filling is damaged, worn, or there is decay underneath. Replacing fillings for cosmetic reasons alone is not always necessary. Your dentist will assess whether replacement is beneficial for your oral health.
7. How long do silver fillings last?
Silver fillings are known for their durability and can last many years with good oral hygiene. Their lifespan depends on factors such as bite pressure and daily habits like grinding. Regular check-ups help ensure they remain in good condition.
8. Do silver fillings require special care?
No special care is needed beyond regular brushing, flossing, and dental check-ups. Good oral hygiene helps extend the life of the filling and prevents further decay. If you notice any discomfort or damage, it’s best to have it checked promptly.
