Dental amalgam, commonly known as silver fillings, is a dental material used to fill cavities caused by tooth decay. It is composed of a mixture of metals, including mercury, silver, tin, and copper. Dental amalgam has been widely used for over 150 years due to its durability, affordability, and resistance to wear. However, concerns have been raised about the potential health effects of mercury in dental amalgam, particularly its neurotoxicity.
In recent years, there has been a growing movement to reduce the use of dental amalgam, and many countries have restricted or banned its use. In the United States, the Food and Drug Administration (FDA) continues to allow the use of dental amalgam, but it has issued warnings about its potential health effects. The FDA recommends that pregnant women, children under 6 years of age, and people with certain medical conditions avoid dental amalgam fillings.
There are several alternative materials to dental amalgam that can be used to fill cavities, including composite resins, glass ionomer cements, and ceramic materials. These materials are generally more expensive than dental amalgam, but they are also considered to be safer and more aesthetically pleasing.

Safety
Concerns about the safety of mercury fillings have led to a decline in their use. Mercury is a toxic metal, and exposure to it can have adverse health effects. The primary concern with mercury fillings is that they can release mercury vapor into the body, which can be inhaled or absorbed through the skin. Mercury vapor can accumulate in the body over time and can cause a variety of health problems, including neurological damage, kidney damage, and developmental disorders.

There are several alternative materials to dental amalgam that can be used to fill cavities, including composite resins, glass ionomer cements, and ceramic materials. These materials are generally more expensive than dental amalgam, but they are also considered to be safer and more aesthetically pleasing.
Alternatives
As concerns about the safety of mercury fillings have grown, dentists have increasingly turned to alternative materials for filling cavities. Composite resins, glass ionomer cements, and ceramic materials are all considered to be safer and more aesthetically pleasing than mercury fillings.
- Composite resins are a tooth-colored material that is made from a mixture of plastic and glass. They are strong and durable, and they can be used to repair both front and back teeth.
- Glass ionomer cements are a type of dental cement that is made from a mixture of glass and acrylic acid. They are strong and durable, and they can release fluoride, which helps to prevent tooth decay.
- Ceramic materials are a type of dental material that is made from a mixture of ceramic and glass. They are strong and durable, and they are highly resistant to wear and tear.
These alternative materials are all considered to be safe and effective for filling cavities. They are also more aesthetically pleasing than mercury fillings, and they can be matched to the color of your teeth.
Durability
The durability of mercury fillings is a key factor in their continued use. Mercury fillings are able to withstand the forces of chewing and biting, and they can last for many years without needing to be replaced. This makes them a cost-effective option for filling cavities.
- Longevity: Mercury fillings have a long lifespan, lasting an average of 10-15 years or more with proper care.
- Strength: Mercury fillings are strong and can withstand the forces of chewing and biting without breaking or chipping.
- Resistance to wear: Mercury fillings are resistant to wear and tear, making them a durable option for filling cavities in areas of the mouth that are subject to heavy use.
Despite their durability, mercury fillings have a number of disadvantages, including their potential health risks and their unaesthetic appearance. As a result, many dentists are now using alternative materials, such as composite resins and ceramic materials, to fill cavities.
Cost
The cost of dental fillings is a significant factor for many patients. Mercury fillings are typically less expensive than alternative materials, such as composite resins and ceramic materials. This is because mercury is a relatively inexpensive metal, and it is easy to work with. As a result, dentists can offer mercury fillings at a lower cost to their patients.
The lower cost of mercury fillings has contributed to their continued use, despite concerns about their safety. However, it is important to note that the cost of dental fillings should not be the only factor that patients consider when making a decision about which type of filling to get. Patients should also consider the safety, durability, and aesthetics of different filling materials before making a decision.

Appearance
The appearance of dental fillings is an important consideration for many patients. Mercury fillings are noticeable and can be unsightly, especially when they are placed in visible areas of the mouth. This is because mercury fillings are a dark color and they can reflect light, making them stand out from the surrounding teeth.
- Unaesthetic: Mercury fillings are not as aesthetically pleasing as other types of fillings, such as composite resins and ceramic fillings.
- Dark color: Mercury fillings are a dark color, which can make them noticeable, especially in visible areas of the mouth.
- Light reflection: Mercury fillings can reflect light, making them even more noticeable.
- Metal taste: Mercury fillings can leave a metallic taste in the mouth, which some people find unpleasant.
Due to their unsightly appearance, many patients are now opting for alternative materials, such as composite resins and ceramic materials, to fill their cavities. These alternative materials are more aesthetically pleasing and they can be matched to the color of the surrounding teeth.
Toxicity
Mercury is a toxic metal that can have adverse health effects, including damage to the brain, kidneys, and lungs. Exposure to mercury can occur through inhalation, ingestion, or skin contact. Dental amalgam fillings are a major source of mercury exposure for the general population. When dental amalgam fillings are placed or removed, mercury vapor is released. This vapor can be inhaled by the patient and the dental staff. It can also be absorbed through the skin.Children and pregnant women are particularly vulnerable to the effects of mercury exposure. Mercury can cross the placenta and accumulate in the developing fetus. It can also be passed to infants through breast milk. Exposure to mercury in the womb or during infancy can lead to developmental problems, including learning disabilities and impaired motor skills.Due to the potential health risks associated with mercury exposure, many countries have restricted or banned the use of dental amalgam fillings. In the United States, the Food and Drug Administration (FDA) continues to allow the use of dental amalgam, but it has issued warnings about its potential health effects. The FDA recommends that pregnant women, children under 6 years of age, and people with certain medical conditions avoid dental amalgam fillings.

The use of dental amalgam fillings has declined in recent years due to concerns about the potential health effects of mercury. However, dental amalgam fillings are still widely used in many parts of the world. It is important for patients to be aware of the potential risks and benefits of dental amalgam fillings before making a decision about whether or not to get them.
