When you visit the dentist to get a dental filling, you may wonder how long it will last. Fillings are a common dental treatment for cavities, but not all fillings are the same. Different materials have different lifespans, and several factors can influence how long your filling will last. In this article, we’ll discuss the different types of fillings, factors affecting their longevity, and how you can make your fillings last as long as possible.
What is a Dental Filling?
A dental filling is a treatment used to restore a tooth that has been damaged by decay or cavities. When a dentist fills a cavity, they remove the decayed part of the tooth and replace it with a material that restores the tooth’s structure. The goal of a filling is to prevent further decay, protect the tooth, and restore its function.
There are various materials used for fillings, including amalgam (silver), composite resin (tooth-colored), gold, and porcelain. The type of material used will affect the lifespan and durability of the filling.
Types of Dental Fillings and Their Longevity
1. Amalgam Fillings (Silver Fillings)
Amalgam fillings are made from a combination of metals, including silver, mercury, tin, and copper. These fillings are durable and have been used for over a century. Amalgam fillings are most commonly used for fillings in the back teeth, where the pressure from chewing is the greatest.
How long do they last?
Amalgam fillings are known for their durability and can last anywhere from 10 to 15 years, and sometimes even longer with proper care. They are resistant to wear and tear, making them a popular choice for restoring molars.
2. Composite Resin Fillings (Tooth-Colored Fillings)
Composite resin fillings are made of a mixture of plastic and glass. These fillings are designed to match the natural color of your teeth, making them a popular choice for fillings in the front teeth.
How long do they last?
Composite resin fillings typically last between 5 to 10 years. While they may not be as durable as amalgam fillings, they are a great option for people who want a more aesthetic solution. However, they may wear down faster over time, especially in areas that experience a lot of pressure from chewing.
3. Gold Fillings
Gold fillings are made from a mixture of gold, copper, and other metals. These fillings are custom-made in a dental laboratory to fit your tooth perfectly.
How long do they last?
Gold fillings are known for their longevity and can last 15 to 20 years, or even longer with proper care. They are extremely durable and resistant to corrosion, making them an excellent option for back teeth. However, gold fillings are more expensive than other types and are not as aesthetic since they do not blend with the natural color of your teeth.
4. Porcelain Fillings (Inlays and Onlays)
Porcelain fillings are custom-made to fit your tooth. They are often used for larger cavities and can be a good option for people who want a natural-looking filling that matches the color of their teeth. Porcelain inlays and onlays are created in a dental laboratory and then placed in the cavity.
How long do they last?
Porcelain fillings can last between 10 to 15 years, depending on how well they are cared for. They are more durable than composite resin fillings but may not be as strong as gold or amalgam fillings.
5. Resilon Fillings
Resilon is a relatively new type of filling material. It is made from thermoplastic compounds that can be heated and molded to fit the cavity. This material is sometimes used in root canals, but it can also be used as a filling.
How long do they last?
Resilon fillings can last up to 10 years or longer with proper care. However, they are not as widely used as other materials like composite resin or amalgam, so their longevity can depend on how the material is applied.
Factors That Affect the Lifespan of Dental Fillings
While the material of your filling is a major factor in determining how long it will last, other factors can also play a role in the longevity of your filling. Let’s take a look at some of these factors.
1. Location of the Filling
The location of your filling can affect how long it will last. Fillings in the back teeth, especially the molars, are subject to more pressure from chewing and grinding. This means that fillings in these areas may wear down faster than those in the front teeth, which are used less for grinding food.
2. Size of the Cavity
The size of the cavity being filled can also impact the lifespan of the filling. Larger cavities may require larger fillings, which may not be as durable as smaller fillings. Additionally, the more material that is used to fill a cavity, the greater the likelihood of the filling experiencing stress or fracture over time.
3. Oral Hygiene Habits
Good oral hygiene is essential for maintaining the health of your fillings and your teeth. Brushing and flossing regularly can help prevent plaque and bacteria from building up around the filling, reducing the risk of decay or damage. Using mouthwash and visiting your dentist for regular check-ups can also help ensure that your fillings stay in good condition.
4. Grinding and Clenching
People who grind or clench their teeth (often due to stress) put extra pressure on their fillings. This can cause fillings to wear down faster and may lead to cracks or fractures in the filling. If you have this habit, your dentist may recommend a night guard to protect your fillings.
5. Dietary Habits
Your diet can have a significant impact on the longevity of your dental fillings. Foods and drinks that are highly acidic or sugary can break down fillings more quickly. Hard foods, like nuts or ice, can also put extra pressure on fillings and cause them to crack. It’s important to avoid chewing on hard objects to prolong the life of your fillings.
6. Age of the Filling
Fillings naturally wear down over time. As the material ages, it may become more prone to cracking, chipping, or discoloration. It’s important to have regular dental check-ups to ensure that your fillings are still in good condition and that there is no decay around the edges.
7. Dental Treatment and Care
The type of dental treatment and care you receive can also affect the lifespan of your fillings. If you have a cavity filled and the filling is not placed properly or if the cavity is not fully cleaned before the filling is applied, it can lead to premature filling failure. Always make sure you see a reputable dentist for your dental treatments.
How Can You Make Your Fillings Last Longer?
While dental fillings are durable, there are things you can do to help extend their lifespan. Here are a few tips:
1. Maintain Good Oral Hygiene
Brush your teeth twice a day with fluoride toothpaste, floss daily, and use mouthwash to keep your teeth and gums healthy. Keeping the area around your fillings clean will reduce the risk of decay and help prevent the filling from becoming loose or damaged.
2. Avoid Hard Foods
Avoid chewing on hard foods like ice, nuts, or hard candy, as these can put pressure on your fillings and cause them to crack or break.
3. Wear a Night Guard
If you grind or clench your teeth at night, consider wearing a night guard to protect your fillings from excessive wear.
4. Visit Your Dentist Regularly
Make sure to visit your dentist for regular check-ups and cleanings. Your dentist will be able to spot any potential problems with your fillings and recommend solutions before the issue becomes serious.
5. Be Mindful of Your Diet
Try to avoid acidic or sugary foods and drinks that can damage your fillings. Drinking plenty of water can help rinse away food particles and bacteria, reducing the risk of damage.
Conclusion
Dental fillings are an essential part of maintaining good oral health, and they can last many years with proper care. The lifespan of a filling depends on the material used, the location of the filling, your oral hygiene habits, and other factors like teeth grinding and dietary choices. By following good dental practices and taking care of your fillings, you can ensure they last as long as possible and keep your smile healthy.
Remember to visit your dentist regularly to ensure that your fillings are in good condition and replace any that may have worn down over time. With proper care, your dental fillings can serve you well for many years.
