The use of mercury fillings, also known as dental amalgam, in dentistry has been a topic of debate for many years. Dental amalgam is a mixture of metals, including mercury, silver, tin, and copper, that has been used to fill cavities in teeth since the 1800s. Mercury is a toxic substance, and concerns about its potential health effects have led to a decline in the use of amalgam fillings in recent years.
Despite the concerns, amalgam fillings are still used by some dentists because they are durable and relatively inexpensive. They are also less likely to fracture than other types of fillings. However, due to the potential health risks, many countries have banned or restricted the use of amalgam fillings. In the United States, the Food and Drug Administration (FDA) has classified amalgam fillings as safe and effective for use in adults and children over the age of 6.
There are a number of alternative filling materials available, including composite resins, glass ionomer cements, and ceramics. These materials are generally more expensive than amalgam fillings, but they are also less likely to contain toxic substances. Ultimately, the decision of whether or not to use amalgam fillings is a personal one that should be made in consultation with a dentist.

Ultimately, the decision of whether or not to use amalgam fillings is a personal one that should be made in consultation with a dentist. There are both risks and benefits to consider, and each patient should weigh the options carefully before making a decision.
Toxicity
Mercury is a toxic heavy metal that can damage the brain, kidneys, and other organs. It is released from amalgam fillings in small amounts over time, and these amounts can accumulate in the body. Concerns about the potential health effects of mercury have led to a decline in the use of amalgam fillings in many countries.
In the United States, the Food and Drug Administration (FDA) has classified amalgam fillings as safe and effective for use in adults and children over the age of 6. However, the FDA also acknowledges that there is some evidence that mercury from amalgam fillings can be harmful to the developing brains of children and fetuses. As a result, the FDA recommends that pregnant women and children under the age of 6 avoid getting amalgam fillings.
There are a number of alternative filling materials available that do not contain mercury. These materials include composite resins, glass ionomer cements, and ceramics. These materials are generally more expensive than amalgam fillings, but they are also less likely to cause health problems.
The decision of whether or not to get amalgam fillings is a personal one. Patients should weigh the risks and benefits of amalgam fillings before making a decision.
Durability
The durability and affordability of amalgam fillings are key factors contributing to their continued use by dentists. Amalgam fillings can last for 10-15 years on average, which is longer than most other types of fillings. They are also less likely to fracture or break than other materials. This makes them a good choice for patients who are looking for a long-lasting and affordable filling material.
- Cost-effective: Amalgam fillings are the most affordable type of filling material. This makes them a good option for patients who are on a budget.
- Easy to place: Amalgam fillings are relatively easy to place, which makes them a good choice for dentists who are short on time.
- Versatility: Amalgam fillings can be used to fill both small and large cavities. This makes them a versatile option for dentists.
Despite their durability and affordability, amalgam fillings have some drawbacks. They are not as aesthetically pleasing as other types of fillings, and they can cause allergic reactions in some patients. Additionally, amalgam fillings contain mercury, which is a toxic metal. However, the amount of mercury released from amalgam fillings is very small, and it is not considered to be a health risk for most people.
Safety
The FDA's classification of amalgam fillings as safe and effective is a key factor in the continued use of these fillings by dentists. The FDA's decision was based on a review of scientific evidence, which found that amalgam fillings are safe for use in the vast majority of people. The FDA also found that amalgam fillings are effective in preventing tooth decay and restoring damaged teeth.
Despite the FDA's classification, there is some debate about the safety of amalgam fillings. Some people believe that the mercury in amalgam fillings can cause health problems, such as neurological damage and kidney problems. However, the FDA maintains that the amount of mercury released from amalgam fillings is very small and does not pose a health risk to most people.
The FDA's classification of amalgam fillings as safe and effective is an important factor in the decision of whether or not to use these fillings. Patients should weigh the risks and benefits of amalgam fillings before making a decision.
Alternatives
The availability of alternative filling materials has played a significant role in the decline in the use of mercury fillings. These alternatives, such as composite resins, glass ionomer cements, and ceramics, offer several advantages over amalgam fillings.
Composite resins are tooth-colored, which makes them more aesthetically pleasing than amalgam fillings. They are also less likely to cause allergic reactions and do not contain mercury. Glass ionomer cements release fluoride, which helps to strengthen teeth and prevent decay. Ceramics are the most durable type of filling material and are also very resistant to wear and tear.
The development of alternative filling materials has given dentists more options for restoring decayed teeth. These materials are safer and more effective than amalgam fillings, and they offer a more natural appearance. As a result, amalgam fillings are being used less and less frequently.
However, amalgam fillings are still used by some dentists because they are durable and relatively inexpensive. They are also less likely to fracture than other types of fillings. The decision of whether or not to use amalgam fillings is a personal one that should be made in consultation with a dentist.
Cost
The cost of dental fillings is a major factor in the decision of whether or not to use amalgam fillings. Amalgam fillings are the least expensive type of filling material, costing an average of $50 to $100 per filling. Alternative filling materials, such as composite resins and ceramics, can cost up to $250 per filling.
- Affordability: Amalgam fillings are the most affordable type of filling material, making them a good option for patients who are on a budget.
- Insurance coverage: Amalgam fillings are often covered by dental insurance, which can further reduce the cost to patients.
- Availability: Amalgam fillings are widely available and can be placed by most dentists.
The lower cost of amalgam fillings makes them a more attractive option for dentists and patients alike. However, it is important to weigh the cost of amalgam fillings against the potential health risks before making a decision.
Availability
The wide availability of amalgam fillings is a major factor contributing to their continued use by dentists. Amalgam fillings are available in most dental offices and can be placed by most dentists. This makes them a convenient and accessible option for patients.
In contrast, alternative filling materials, such as composite resins and ceramics, may not be as widely available. These materials require specialized training and equipment to place, and they may not be available in all dental offices. This can make them less accessible and more expensive for patients.
The availability of amalgam fillings is a key reason why dentists still use them. Amalgam fillings are a convenient and affordable option for patients, and they are widely available. As a result, amalgam fillings are likely to continue to be used by dentists for many years to come.
