A majority of people will develop at least one cavity in their lifetimes and will therefore experience a treatment of this early form of tooth decay with a dental filling. You might have received a filling in your childhood. But you may not know what this filling does for your smile.
A dental filling, usually made from composite resin, fills a hole in your tooth after a dentist drills away the decayed part of your tooth.
When it comes to materials, you’ll typically have two main options: amalgam or composite. Amalgam is a silver-colored filling made from a blend of metals, and it’s been a reliable choice in dentistry for decades. Composite resin, on the other hand, is a tooth-colored material crafted from a mixture of plastic and glass particles. Many people prefer composite for its ability to blend in seamlessly with your natural tooth, though both types are safe and effective at restoring your smile.
You can feel confident that tooth decay is gone for good and that the filling will keep this vulnerable area of your smile protected in the aftermath. Read on to learn more about dental fillings and what you can expect after this treatment from your dentist.
Why Choose Composite Resin Fillings?
When it comes to restoring a tooth after a cavity, your dentist will likely offer you a choice between amalgam and composite resin materials. Both options have their merits, but composite resin fillings are becoming increasingly popular for several reasons.
First, composite resin is designed to blend in with your natural tooth color. Unlike traditional metal amalgam, which can appear silver or gray in your smile, composite fillings are virtually invisible once placed. This makes them an attractive option for anyone concerned about aesthetics—especially when repairing front teeth.
Some patients also report less sensitivity to hot or cold with composite resin compared to metal fillings, which can sometimes conduct temperature changes more easily. And while amalgam fillings do contain minor amounts of mercury, many people prefer the peace of mind that comes with mercury-free composite materials—though it’s important to note that the American Dental Association considers amalgam fillings safe.
In short, if you want a durable, discreet, and tooth-colored restoration that blends seamlessly with your natural smile, composite resin fillings are often the go-to choice. You can feel confident that tooth decay is gone for good and that the filling will keep this vulnerable area of your smile protected in the aftermath.
What Are the Main Types of Dental Fillings?
When it comes to treating cavities, dentists usually offer two primary types of dental fillings: amalgam and composite resin.
Amalgam fillings have been a staple in dental care for generations. Crafted from a blend of metals—including silver, tin, copper, and trace amounts of mercury—these fillings are well-known for their impressive durability. Because they’re particularly tough, dentists often use them for molars, which experience the most chewing force.
On the other hand, composite resin fillings have become increasingly popular in recent years, especially for those seeking a more discreet restoration. Made from a mixture of plastic and tiny glass particles, these fillings are shaded to match the color of your natural teeth. As a result, composite fillings blend seamlessly into your smile, making them a go-to choice for cavities in more visible teeth.
While both types are perfectly safe and effective, each comes with its own set of advantages:
- Amalgam fillings typically last longer and tend to withstand biting forces better, making them ideal for back teeth.
- Composite fillings offer a more natural appearance and are less likely to cause temperature sensitivity, which some patients experience with metal fillings.
Understanding the differences between these materials can help you make an informed decision if you ever need a cavity filled. Read on to learn more about dental fillings and what you can expect after this treatment from your dentist.
What Are the Differences Between Amalgam and Composite Resin Fillings?
When it comes to cavity treatment, your dentist might offer a couple of distinct options for fillings: amalgam and composite resin. These choices differ in several ways, each offering unique advantages depending on your dental needs and cosmetic preferences.
Amalgam Fillings:
Amalgam has a long-standing history in dental care. Composed of a blend of various metals, this option is known for its strength and durability. Amalgam is often used for molars and other teeth
that do a lot of heavy chewing, since it can stand up to the pressures of daily biting without breaking down as quickly. However, because of its metallic color, it will be noticeable against your natural tooth enamel.
Composite Resin Fillings:
Composite resin is a more modern material that leverages a combination of fine glass and plastic particles. One of its key benefits is its ability to blend seamlessly with your teeth, creating a tooth-colored filling that many patients find much more appealing. Composite resin also bonds directly to the tooth, which can help preserve more of your natural tooth structure.
Consider these points when weighing your options:
- Composite fillings offer a discreet, natural look and are less likely to cause temperature sensitivity, but may not last quite as long as amalgam.
- Amalgam fillings generally outlast composite in areas that experience more intense biting
- Both materials are safe and effective, but the aesthetics and potential for minor sensitivity differences may influence your choice.
Ultimately, the right filling for you will depend on the tooth being treated, your personal preferences, and your dentist’s recommendation.
How Long Do Dental Fillings Last?
Dental fillings will effectively restore the shape and function of your teeth after getting rid of a cavity. But though durable, these fixtures do not last in your smile forever. It can stay in the tooth for ten years with proper care and maintenance.
The malleable resin molds to the appropriate shape of your tooth before the dentist cures it, solidifying it into place as a filling. It acts as a cement to stay firmly in the tooth. So you can eat and perform other oral functions as you normally would. But you will need to take proper care of your smile and dental work to avoid issues with the filling.
How Long Should You Expect Your Filling to Last?
On average, metal fillings can last about 15 years, while composite resin fillings typically remain effective for 10 to 12 years. Patients who maintain excellent oral hygiene and regular dental checkups may see their fillings last even longer. Conversely, bad habits, lifestyle choices, or apredisposition to tooth decay can shorten the lifespan of a filling, making early replacement necessary.
Sticking to good oral care routines and keeping up with your dental appointments can help you get the most out of your dental work—so your smile stays strong and healthy for years to come.
Can a Dental Filling Fall Out of a Tooth?
If exposed to high or abnormal pressures, a dental filling could become loose, wear down, or fall out of the tooth. If this happens, the protective seal created by the cured resin breaks. Then the tooth will be in danger of plaque, bacteria, and other harmful particles.
You should consider this dental damage to be an emergency and call your dentist as soon as you can. They will likely ask you to come to their office for an urgent dental evaluation, repair, and replacement of the filling.
Biting down on a hard item or at an awkward angle could generate pressure that would cause this type of harm to your dental work. Constant grating from teeth grinding could also lead to this damage. So pay attention to your oral habits after receiving a filling.
Routine Dental Visits Are Essential
Beyond protecting your filling from excessive pressure, you’ll want to keep up with regular dental visits. Seeing your dentist at least twice a year means your fillings—and your entire smile—get professional attention. Dentists can spot early signs of wear or damage in your fillings, letting you address small issues before they become bigger headaches. Plus, professional cleanings remove stubborn plaque and tartar, especially in those hard-to-reach spots between teeth and along the gumline, helping to keep tooth decay at bay and prolong the life of your dental work.
Staying diligent about both your daily oral hygiene and your routine dental checkups is the best way to ensure your fillings remain secure and your smile stays healthy.
How Do I Care for Dental Fillings?
You can take care of your dental fillings by maintaining good overall oral health habits. This will mean practicing good oral hygiene. Otherwise, plaque will linger on your smile and cause damage that could impact the fit of your filling.
You should also avoid the behaviors that create pressures that might hurt your dental filling. If you have trouble avoiding these actions, ask your dentist for preventative dental care advice.
What Dietary Choices Can Help Extend the Lifespan of Dental Fillings?
Your diet can play a significant role in how well your dental fillings hold up over time. To support both your natural teeth and any restorative dental work, consider these simple strategies:
- Limit your intake of sugary foods and Sugar feeds the bacteria that contribute to tooth decay, which can weaken the area around your fillings.
- Opt for foods high in calcium and vitamins, like leafy greens, dairy products, and nuts, to help strengthen your enamel and keep your teeth healthy overall.
- Be cautious with very hard, sticky, or crunchy snacks—think hard candies, caramels, or popcorn kernels—as these could put too much pressure on your fillings and risk dislodging or damaging them.
Choosing tooth-friendly foods and staying mindful of your oral habits will give your dental fillings the best chance to stay intact for years to come.
Directly after receiving a dental filling, adhere to your dentist aftercare instructions. This will ensure that the filling settles into place properly. If you notice any issues or abnormal side effects, call your dentist right away.
