Composite and amalgam fillings both repair cavities effectively, but they differ in appearance, durability, and where in the mouth they tend to work best. The right choice usually comes down to the location of the cavity, your budget, and your personal preference.
When you have a cavity, your dentist will recommend a filling, but did you know there is more than one type? Composite and amalgam fillings are the two most common options, and each comes with its own set of benefits depending on your needs, budget, and preferences. Understanding the difference can help you make a more informed decision about your dental care.
At Esteem Dental in Winter Garden, our team offers both composite and amalgam fillings as part of our comprehensive restorative dentistry services. Whether you are coming in for a routine checkup or addressing a cavity for your child, we are proud to be a multi-specialty, one-stop practice where your whole family can get the care they need under one roof. Our team will walk you through your options and help you choose the right filling for your smile.
What Are Amalgam Fillings?
Amalgam fillings have been used in dentistry for over 150 years. They are made from a combination of metals, including silver, tin, copper, and mercury, which work together to create a durable, long-lasting material.
Here is what makes amalgam fillings a common choice:
- Durability: they can last 10 to 15 years or more with proper care.
- Cost-effectiveness: amalgam is generally less expensive than composite.
- Strength: they hold up well under the pressure of chewing, making them a reliable option for back teeth.
- Speed: they are typically quicker to place than composite fillings.
Amalgam fillings are most often recommended for molars and premolars, where strength and durability matter most. While their silver appearance makes them more visible in the mouth, many patients still choose them for their proven track record.
What Are Composite Fillings?
Composite fillings are made from a tooth-colored resin material that blends in naturally with your enamel. According to the National Library of Medicine, tooth-colored restorative materials have become increasingly popular as patients prioritize aesthetics alongside function.
Composite fillings are preferred for several reasons:
- Aesthetics: they match your natural tooth color for a seamless look.
- Versatility: they can be used on both front and back teeth.
- Bonding: composite bonds directly to the tooth, which may help preserve more of the natural structure.
- Mercury-free: they contain no metal, which some patients prefer for peace of mind.
Composite fillings are an excellent option for visible teeth or for patients who want a more natural-looking result. They may require slightly more maintenance over time, but they remain a popular choice for both adults and children.
How Long Does Each Type of Filling Last?
Amalgam fillings tend to have the edge on raw durability, often lasting 10 to 15 years or more, while composite fillings typically last 5 to 10 years before they may need to be replaced or touched up. Composite fillings can wear a bit faster in areas that take heavy chewing pressure, which is one reason amalgam remains a common choice for back molars even though composite has become more popular overall. Regular checkups let us catch early signs of wear on either type before a filling needs full replacement.
How to Choose Between Composite and Amalgam Fillings for Adults and Children
Choosing between composite and amalgam fillings depends on a few key factors. Your dentist will consider the location of the cavity, the size of the filling needed, your insurance coverage, and your personal preferences. For back teeth that experience heavy chewing pressure, amalgam may be the more durable choice. For front teeth or smaller cavities, composite is often the preferred option. Both types are safe and effective, and both come up regularly during our dental exams and cleaning appointments.
Both composite and amalgam fillings can also be used for children, although composite is often the preferred choice for younger patients because of its natural appearance. At Esteem Dental, our pediatric dentistry team takes special care to help kids feel comfortable throughout the process. If your child needs a filling on a back tooth with more significant decay, our page on stainless steel crowns for children covers another option worth discussing with your dentist. We consider the size of the tooth, the child’s age, and the location of the cavity when making our recommendation.
Are There Other Filling Materials Available?
Composite and amalgam are the two most common filling materials, but they are not the only options. Glass ionomer fillings, for example, release fluoride over time and are sometimes used for small cavities or in areas less exposed to heavy chewing pressure, though they tend to be less durable than composite or amalgam. Gold and porcelain restorations are also available for larger cavities or where extra strength and longevity matter most, though these options typically involve a higher cost and an additional office visit to place.
For the vast majority of everyday cavities, composite and amalgam remain the most practical choices, balancing cost, durability, and appearance. Your dentist can walk you through whether a less common material might be worth considering for your specific situation.
What to Expect During and After Your Filling
Both composite and amalgam fillings are placed using local anesthesia, so you should not feel pain during the procedure itself. Composite fillings are applied in thin layers and hardened with a curing light, which is why they can sometimes take a little longer to place than amalgam. Afterward, some mild sensitivity to hot or cold is common for a few days, and our page on how soon you can eat after a dental filling covers what to expect as the area settles.

Frequently Asked Questions About Composite and Amalgam Fillings
Are amalgam fillings safe?
Amalgam fillings have been used safely in dentistry for over 150 years and remain an accepted treatment option today. Patients who prefer to avoid metal-containing materials for personal reasons can choose composite fillings instead.
Can I replace an old amalgam filling with a composite one?
Yes, existing amalgam fillings can often be replaced with composite once they wear out or if you prefer a more natural appearance. Your dentist will evaluate the tooth to confirm it is a good candidate before making the switch.
Does insurance cover composite fillings the same way it covers amalgam?
Coverage varies by plan. Some insurance plans cover composite fillings at the same rate as amalgam, while others only cover the cost equivalent to amalgam and require you to pay the difference for composite on back teeth. Our team can help you check your specific benefits.
How do I know if my filling needs to be replaced?
Signs that a filling may need attention include visible cracks, rough edges, new sensitivity, or a filling that feels loose. Regular checkups let your dentist spot wear before it leads to a bigger problem.
