Amalgam: A Dental Filling Material Composed Of A Mixture Of Metals, Including Mercury, Silver, Tin, And Copper.
If you’ve ever had a cavity, then chances are you know what dental amalgam is. This filling material has been used for over 150 years and is still the most popular choice for filling cavities today. It’s composed of a mixture of metals, including mercury, silver, tin, and copper. But while it’s an effective way to restore teeth damaged by decay or injury, there may be some concerns about its safety and effectiveness. In this blog post, we’ll explore everything you need to know about dental amalgam – from its different types to alternatives that might work better for your needs!
Cost Ranges
The cost of dental amalgam fillings can vary based on factors such as the size of the cavity and the location of the dental practice. On average, prices can range from $50 to $150 per filling. Comparatively, composite fillings, which are an alternative to amalgam, can cost between $90 and $250.
Alternatives to Dental Amalgam
- Composite Resins: These tooth-colored materials offer a more aesthetic option and are suitable for visible teeth. They bond directly to the tooth, providing additional support.

Local Tips
When considering dental treatments, it is advisable to consult with a local dentist who understands regional healthcare guidelines and can provide personalized advice. Ask about the dentist's experience with different filling materials and their recommendations based on your dental history and lifestyle.
What is Amalgam?
Dental amalgam is a filling material that has been used by dentists for more than 150 years. It’s composed of a mixture of metals, including mercury, silver, tin, and copper. Amalgam fillings are known for their durability and cost-effectiveness.
Mercury is the main component in dental amalgam, making up about 50% of the total weight. The rest is made up of other metals like silver, tin and copper. Once mixed together with mercury in a process called amalgamation, it forms a pliable substance that can be molded to fit into cavities where it hardens over time.
Amalgams have been considered safe by many health organizations around the world, including the World Health Organization (WHO) and American Dental Association (ADA). However, concerns about mercury toxicity have led some people to question its use as a filling material.
Despite this concern there are still many dentists who continue to use dental amalgams because they are durable and long-lasting compared to other types of fillings such as composite or resin-based fillings. Ultimately whether or not you choose an amalgam filling will depend on your personal needs and preferences along with your dentist’s recommendation based on clinical judgement
The Different Types of Amalgams
There are different types of amalgams that are commonly used in dental fillings. The traditional or conventional amalgam is composed of a mixture of metals, including mercury, silver, tin, and copper. This type of amalgam has been used for over 150 years due to its durability and strength.
Another type of amalgam is the high-copper alloy which contains more copper than the traditional one. It is known for its improved properties such as better resistance to corrosion and shrinkage compared to the conventional one.
The third type is known as the spherical or dispersed-phase amalgam which uses particles with a round shape instead of powdered metals. This results in a stronger filling material with less creep deformation and wear resistance.
There’s also an admixed dental amalgam which combines both powdered metal alloys and spherical particles resulting in a strong filling material with good dimensional stability.
It’s important to note that all these types contain mercury; hence patients should be well-informed by their dentist about their options when getting dental fillings.
Pros and Cons of Amalgam
Amalgam has been used as a dental filling material for over 150 years. It is known for its durability and strength, making it an ideal choice for back teeth that undergo significant pressure from chewing. However, like any dental material, amalgam has its pros and cons.
One of the biggest advantages of amalgam is its longevity. Amalgams can last up to 10-15 years or longer with proper care. They are also relatively inexpensive compared to other types of fillings like composite resin or porcelain.
Another advantage of amalgam is their strength. This makes them ideal for use in molars where they need to withstand the forces generated during chewing.
However, one major disadvantage of amalgam is their unsightly appearance which can be noticeable when placed on front teeth. Another concern surrounding amalgams is the presence of mercury in the mixture; although studies have shown that there isn’t enough exposure to cause health risks.
In addition, some patients may experience mild sensitivity after getting an amalgam filling due to thermal conductivity differences between metal and natural tooth structure.
While there are pros and cons associated with using dental amalgams as a filling material – it’s important that your dentist discusses these options with you so you can make an informed decision about what’s best suited for your individual needs
What are the side effects of Amalgam?
Amalgam fillings have been in use for over 150 years, and while they are durable and long-lasting, there are still some concerns about their potential side effects.
One of the primary concerns regarding amalgam fillings is that they contain mercury, which is a toxic substance known to cause various health problems when exposed to high levels. However, research has shown that the amount of mercury released from amalgam fillings is generally too small to cause any significant harm.
Some people may experience an allergic reaction or sensitivity towards one or more components of dental amalgams such as silver or copper. This could result in symptoms like swelling, itching, rashes or even difficulty breathing.
In rare cases where patients have many large amalgam restorations placed near each other can lead to galvanic shock leading to nerve pain and damage.
Additionally, chewing food and exposure to hot or cold temperatures may cause the metal filling material to expand or contract slightly causing tooth fractures due to its non-bonded nature with teeth structure.
It’s important for individuals who are concerned about potential risks associated with dental amalgams should speak with their dentist regarding alternative treatment options available based on their unique case history before considering having them removed unnecessarily.
How to remove Amalgam fillings?
If you’re considering removing your amalgam fillings, it’s important to know that it can be a complicated process. Here are some steps to help guide you through the procedure:
1. Find a qualified dentist who specializes in safe amalgam removal. They should follow strict protocols such as using rubber dams and high-volume air filtration systems.
2. Prioritize proper preparation before the actual removal process starts, including having an alternative filling material ready for placement once the amalgams have been removed.
3. During the removal process itself, there may be some discomfort due to vibrations and heat from drilling, so local anesthesia is often used.
4. Aftercare is essential following an amalgam filling removal procedure – including avoiding hard or chewy foods for several hours afterward and staying hydrated by drinking plenty of water
5. Finally, get enough rest for faster recovery
While removing dental amalgams can be daunting at first, it’s worth seeking expert advice on how best to proceed with this complex dental procedure if necessary
Alternatives to Amalgam
There are several alternatives to amalgam fillings that patients can consider. One option is composite resin, which is a tooth-colored filling material made of plastic and glass particles. Composite resin is a popular choice because it blends in with the natural color of teeth and does not contain any mercury.
Another alternative to amalgam fillings is porcelain or ceramic restorations. These materials provide an aesthetically pleasing appearance and have high durability, making them ideal for larger cavities.
Gold fillings are another alternative to amalgam, although they tend to be more expensive than other options. Gold has been used in dentistry for centuries due to its durability and strength.
Glass ionomer cement (GIC) also provides an alternative to amalgam fillings. This material contains fluoride, which helps strengthen teeth and prevent further decay.
Ultimately, the best choice for dental fillings depends on each individual’s unique situation and needs. It’s important for patients to discuss their options with their dentist before making a decision on what type of filling material they want.
