Dental Fillings

Everything to Know about the Lifespan of Dental Fillings

When it comes to dental fillings, one of the most necessary things you need to know is how long they typically last. The lifespan of a dental filling will depend on its material, as different materials have different properties that determine how long they stay.

Here are essential things to know about the life span of dental fillings.

3 Common Types of Dental Fillings 

1. Amalgam Fillings 

Amalgam fillings are produced from a combination of metals, including silver, tin, zinc, and copper. They are the most common type of dental filling and are known for their strength. Amalgam fillings can even last up to 15 years before needing to be replaced.

2. Composite Fillings 

Composite fillings are composed of a mixture of plastic and glass particles and are popular because they can match the color of your teeth. These fillings are more aesthetically pleasing than amalgam fillings but could be stronger. Composite fillings typically last for five to seven years before needing to be replaced.

3. Porcelain Fillings

Porcelain fillings are made from a ceramic material fused to the tooth. They are known for their durability and can last up to ten years before needing replacement.

How to Identify You Need to Replace Your Dental Fillings

Dental fillings do not last forever, and you will need to replace them at some point. Knowing when to replace your fillings is vital to maintain good oral hygiene and prevent further damage to your teeth.

Here are three factors to know about the life span of dental fillings that can help you identify when you need to replace them:

1. Fillings Usually Last between Five and 15 Years

Dental fillings are meant to be a long-term solution but are not permanent. The lifespan of a filling will depend on a few considerations, such as the type of material used, how well you take care of your teeth, and how much pressure the filling is exposed to. While fillings are generally expected to last between five and 15 years, you may need to replace them sooner if there are any signs of wear and tear.

2. Signs of Wear and Tear

While fillings are meant to last, being aware of any signs is vital. If you notice that the filling has become loose or cracked, it is likely time to replace it. Additionally, you may need to replace your packing if you experience pain or sensitivity when biting or chewing.

3. Check with Your Dentist

If you are still determining whether or not it is time to replace your filling, it is best to check with your dentist. Your dentist can take a look at your filling and determine if it needs to be replaced. They can also recommend the best type of filling for your needs.


By being aware of the life span of your dental fillings, you can better identify when it is time to replace them. Remember to check with your dentist if you are still determining whether or not you need to replace your filling. Taking good care of your fillings can help prevent further damage to your teeth and keep your oral hygiene in shape.
