What is Amalgam and How is it Used in Dentistry?
Amalgam is a type of dental filling material that consists of a mixture of metals, such as silver, tin, copper and mercury. Amalgam has been used for over 150 years to restore teeth that have been damaged by decay or trauma. Amalgam is also known as silver fillings or metal fillings.
Benefits of Amalgam Fillings
Amalgam fillings have several advantages over other types of dental fillings, such as composite resin or porcelain. Some of the benefits of amalgam fillings are:
- They are durable and can withstand high chewing forces.
- They are relatively inexpensive and widely available.
- They are easy to place and require less tooth preparation than other fillings.
- They have a long history of safety and effectiveness.
Risks of Amalgam Fillings
Amalgam fillings also have some drawbacks that may make them unsuitable for some patients. Some of the risks of amalgam fillings are:
- They contain mercury, which is a toxic metal that can cause allergic reactions or health problems in some people. However, the amount of mercury released from amalgam fillings is very low and below the safety limits set by the World Health Organization.
- They can cause discoloration or staining of the teeth or gums over time.
- They can expand or contract with temperature changes, which can cause cracks or gaps in the tooth or filling.
- They are not aesthetically pleasing and do not match the natural color of the teeth.
Alternatives to Amalgam Fillings
If you are looking for a more natural-looking or mercury-free option for your dental fillings, you may want to consider some of the alternatives to amalgam fillings, such as:
- Composite resin fillings, which are made of a tooth-colored plastic and glass material that can bond to the tooth structure.
- Porcelain fillings, which are made of a ceramic material that can mimic the appearance and strength of natural teeth.
- Gold fillings, which are made of a metal alloy that can last for a long time and resist corrosion.

How to Care for Your Amalgam Fillings
If you have amalgam fillings in your teeth, you should follow some basic guidelines to maintain their function and appearance. Some of the tips for caring for your amalgam fillings are:
- Brush your teeth twice a day with a fluoride toothpaste and floss daily to prevent plaque and tartar buildup.
- Avoid chewing hard or sticky foods that can damage or dislodge your fillings.
- Avoid extreme hot or cold foods and drinks that can cause sensitivity or expansion of your fillings.
- Visit your dentist regularly for checkups and cleanings to monitor the condition of your fillings and detect any signs of decay or damage.
- Inform your dentist if you experience any pain, sensitivity, swelling or infection around your fillings.
How to Replace Your Amalgam Fillings
If you are unhappy with your amalgam fillings or if they are worn out, cracked or leaking, you may want to consider replacing them with a different type of filling material. Replacing your amalgam fillings can improve the appearance and health of your teeth and reduce the risk of mercury exposure. However, replacing your amalgam fillings also involves some costs and risks, such as:
- You may need to pay out-of-pocket for the replacement procedure, as some dental insurance plans may not cover it.
- You may experience some discomfort, bleeding or infection during or after the procedure.
- You may lose some healthy tooth structure during the removal of the old fillings.
- You may need multiple appointments to complete the replacement process.
Therefore, you should weigh the pros and cons of replacing your amalgam fillings and discuss with your dentist the best option for your situation. Your dentist will evaluate the condition of your teeth and fillings and recommend the most suitable type of filling material for you. You should also ask your dentist about the safety precautions and protocols they follow when removing amalgam fillings to minimize the risk of mercury exposure or contamination.
