Composite Dental Fillings Vs. Amalgam Fillings Comparison

Dental fillings are used to help restore teeth damaged by decay and cavities. While there are several different types of dental fillings, the two most common are composite and amalgam. Both are effective at restoring teeth and have their own unique advantages and disadvantages. Understanding the differences between composite and amalgam fillings can help you make an informed decision when it comes to choosing the right filling for your needs.

Appearance One of the key differences between composite and amalgam fillings is the appearance. Amalgam fillings, also known as silver fillings, are made of a mixture of metals, such as silver, tin, copper, and mercury. This gives them a distinct silver color, which can be quite visible when smiling or talking. Composite fillings, on the other hand, are made of a mixture of plastic and fine glass particles, so they are tooth-colored and blend in with the natural color of the tooth.

Durability When it comes to durability, amalgam fillings are generally the more durable option. They can last up to 15 years, while composite fillings typically last between 5 and 7 years.

Cost The cost of composite and amalgam fillings can vary widely, depending on the size and location of the filling. In general, amalgam fillings tend to be less expensive than composite fillings.

Procedure The procedure for getting a composite filling is a bit more involved than for an amalgam filling. The dentist will first need to prepare the tooth by removing the decay and cleaning it. Then, the filling material will be applied, shaped, and hardened with a special light. With an amalgam filling, the process is much simpler. The dentist will simply remove the decay and shape the filling to fit the tooth.

Both composite and amalgam fillings are effective options for restoring teeth damaged by decay. Ultimately, the decision of which type of filling to get should be based on your individual needs and preferences. Be sure to discuss your options with your dentist to determine the best solution for you.

Understanding the Difference Between Composite and Amalgam Fillings

When it comes to fillings, there are two main types to choose from: composite and amalgam. Each type has its own benefits and drawbacks, and it’s important to understand them before making a decision about which type of filling is best for you.

Composite fillings, also known as tooth-colored fillings, are a mixture of plastic and glass. They are designed to match the color of your natural teeth and are often used to fill cavities in the front teeth. They are extremely durable and long-lasting, and they are also the most aesthetically pleasing option.

Amalgam fillings, on the other hand, are made from a combination of metals. They are silver-colored and highly visible, so they are not the best choice for cavities in the front teeth. They are, however, the more affordable option and are very strong.

One of the biggest differences between the two types of fillings is their longevity. Composite fillings typically last anywhere from 5 to 7 years, while amalgam fillings can last between 10 and 15 years. It’s also important to note that composite fillings require more frequent replacement than amalgam fillings, as they are more prone to breaking down over time.

In addition to the differences in longevity, the cost of composite and amalgam fillings also varies significantly. Composite fillings are usually more expensive than amalgam fillings, but they may be covered by insurance depending on the type of policy you have.

Ultimately, the decision of which type of filling is best for you depends on your individual needs. Consider the cost, longevity, and aesthetics before making a decision. Your dentist can help you decide which type is best for your situation.

Pros and Cons of Composite Fillings

Composite fillings are a popular choice among dentists and patients alike, often chosen as a preferred alternative to silver amalgam. A composite filling is a tooth-colored resin material and glass mixture used to restore decayed teeth. They are also used to repair cracked or chipped teeth and to close the spaces between teeth.


One of the biggest benefits of composite fillings is that they look much more natural than silver amalgam fillings. Because the resin can be closely matched to the color of your teeth, it can be virtually unnoticeable. This is especially beneficial for fillings on visible surfaces like front teeth.

Another benefit of composite fillings is that they can be bonded directly to the tooth, providing additional strength and durability. They are especially well-suited for restoring small to mid-size cavities.

Composite fillings also contain no mercury, which is the main component of silver amalgam fillings. This makes them a popular choice for people who are concerned about the possible health risks associated with amalgam fillings.


Although composite fillings offer many benefits, there are also some disadvantages. For one, they aren’t as strong as silver amalgam fillings and may not be suitable for large cavities or molars. Additionally, they can be more expensive and take longer to place than amalgam fillings.

Composite fillings may also require more frequent replacements since they can wear down over time and are prone to staining. They are also not ideal for people who grind their teeth, as the material may not be able to withstand the pressure.

In conclusion, composite fillings offer many benefits, including a more natural look and no mercury content. However, they can be more expensive, require more frequent replacements, and may not be suitable for larger cavities or molars. It’s important to discuss your options with your dentist and weigh the pros and cons before deciding which type of filling is best for you.

Pros and Cons of Amalgam Fillings

Amalgam fillings, also known as silver fillings, have been used for decades as a safe and reliable way to fill cavities and repair tooth decay. However, in recent years, they have come under scrutiny due to concerns about their safety and environmental impact. This article will discuss the pros and cons of amalgam fillings to help you decide if they are the right choice for you.


The biggest advantage of amalgam fillings is their durability. They are strong and long-lasting, which means that they don’t need to be replaced as often as other types of fillings. Amalgam fillings also have a low cost, making them an affordable option for most people.

In addition, amalgam fillings are easy to place and require a relatively short amount of time to complete. They also provide good protection for the teeth, which can help prevent further damage.


The biggest downside of amalgam fillings is their appearance. They are silver in color and can be very noticeable when you smile or laugh. This can make some people feel self-conscious.

In addition, amalgam fillings contain mercury, which can be toxic if it is released into the environment. They also require more drilling and removal of healthy tooth tissue than other types of fillings, which can weaken the tooth structure.


Amalgam fillings are a common and affordable way to fill cavities and repair tooth decay. They are durable and require less time to place than other types of fillings. However, they are not aesthetically pleasing and contain mercury, which can be toxic if it is released into the environment. Ultimately, the decision to use amalgam fillings is up to the individual and their dentist. They should weigh the pros and cons carefully to make an informed decision.
