How Long Do Dental Fillings Last?

When it comes to treating mild to moderate tooth decay, fillings are the most common option. They can prevent decay from spreading, reduce dental pain and sensitivity, and restore the shape and function of a damaged tooth. But how long do fillings last? That really depends on a few factors. In this blog post, you will learn about the average lifespan of fillings, how to make your fillings last longer, and how to tell when your fillings need to be replaced.

The Average Lifespan of Dental Fillings

The lifespan of a dental filling depends on a few factors, including the material used, as well as the size and location of the filling.

On average, amalgam fillings, which are made of a mixture of metals, can last between 10 and 15 years. Composite fillings, which are the most popular option in modern dentistry due to their beautiful appearance and biocompatibility, usually last between 5 and 10 years.

Generally speaking, fillings on molars may wear down faster due to the additional pressure they endure during chewing. Smaller fillings may last longer than larger ones because they do not cover as much surface area.

Tips to Make Your Fillings Last Longer

Here are some tips that can help your fillings last as long as possible:

• Maintain excellent oral hygiene by brushing your teeth twice a day with fluoridated toothpaste and flossing daily to remove plaque and food particles.
• Schedule regular dental checkups and cleanings to identify any issues with your fillings before they worsen.
• Avoid biting down on hard objects, such as ice, pens, or your nails, to prevent placing unnecessary pressure on your fillings.
• Limit your consumption of sugary foods and beverages to reduce the risk of further tooth decay.
• Use a mouthguard at night if you grind your teeth while sleeping, as grinding can cause fillings to crack or wear down prematurely.

Signs That Your Fillings Need to Be Replaced

It is important that you attend a dental checkup and cleaning at least twice a year so your dentist can check on both your natural oral tissues and your fillings. They can inform you when you need to get them replaced. They will look for both missing fillings and damage to the tissues around your fillings.

They may also take some X-rays to look for signs of decay beneath your fillings. Additionally, you should be sure to inform them if you are experiencing unusual pain or sensitivity in a tooth with a filling.

Dental fillings are very durable, but they are not designed to last forever! Keep careful watch on your oral health so you can get old restorations replaced in a timely manner.
