The material from which your dental filling is made will determine how long you can expect it to last.  

If you’ve had a dental filling placed as a treatment for tooth decay, you may be wondering how long it will last. Dental fillings can last for many years, and their longevity will depend on the type of material used and how well you take care of your teeth. In this blog post, we’ll discuss the different types of dental fillings and how to prolong their lifespan.

How long do dental fillings last?

Although it varies from case to case, you can usually expect your dental filling to last about 10 years. The material that is used to fabricate your restoration will play an important part in its lifespan, but there are several other factors that could impact its longevity. Some of these factors include your unique dietary choices; your oral hygiene habits; habits like teeth grinding; and any oral health issues that you have, such as tooth decay or trauma.

What types of fillings are available?  

The most common types of fillings are amalgam and composite fillings.

Amalgam fillings, also known as silver fillings, are made of a combination of metals, including silver and copper. Amalgam fillings have been a popular and effective choice for many years and are made of extremely durable materials. In fact, silver fillings can last for up to 15 years before they need to be replaced.

Composite fillings are made from ceramic and acrylic resins and are designed to match the colour of the natural teeth. These fillings can usually last up to 10 years with the right care.

Although less common, fillings are also available in gold and ceramic. Gold fillings tend to be more expensive than other materials, but are extremely durable, lasting 20 years or more. Ceramic fillings are made from porcelain, a natural-looking and strong material that can last 15 years or more with the proper maintenance.

When should you replace a filling?

If you have had a filling placed, it is possible that you will never have to have it replaced. It is possible, however, for your restoration to wear down or crack over time. Sometimes, fillings can fall out, in which case, they will need to be replaced. If you notice a problem with your filling, it is important that you see your dentist as soon as possible. They will let you know if it’s time to have your restoration replaced.

Does your diet have an impact on your fillings?

One of the factors that can have an impact on the lifespan of your fillings is the food that you eat on a regular basis. Sugary foods and drinks can contribute to the build-up of plaque on your teeth and restorations, which can lead to tooth decay and cavities on healthy teeth, and under your fillings. For this reason, it is advisable that you limit your consumption of processed sugar and that you practice proper oral hygiene.

It is also a good idea to avoid certain hard foods that can damage your teeth and fillings — these include whole nuts, ice, and hard candy.
