The Lifespan of a Dental Filling

Many dentists will not replace dental fillings without good reason. Even if you have a filling that is more than a decade old, it could be several years before it needs replacement. Additionally, regular dental checkups can extend the life of your filling.

How many times can a filling be replaced? The answer depends on different factors, such as:

  • Type of filling material
  • Remaining tooth structure 
  • Sustained sensitivity 

Your dentist will use these factors to determine if your filling can be replaced or if a different kind of dental procedure is more appropriate. 

Material Used 

Fillings can consist of several different types of material. Each one has a varying lifespan and cost. 

  • Glass Ionomer: best for temporary fillings and on surfaces that are not used to chew, such as the side of a molar, and can last up to seven years 
  • Amalgam: best for high durability and low cost and can last up to 15 years
  • Ceramic: best for a filling that needs to match your tooth color and can last up to 15 years
  • Gold: best for longevity as they last the longest, up to 30 years

Remaining Tooth Structure 

Each time a filling needs replacement, your dentist must drill away new decay. This increases the size of the filling while decreasing tooth structure. Eventually, a tooth with multiple cavity treatments will become too fragile to hold the filling. When this occurs, your dentist may discuss other treatment options with you. 

Reasons to Replace a Filling 

Though your dentist will not replace a filling without good reason, you may require a replacement long before the filling falls out. Reasons to replace a filling include: 

  • A routine exam discovers the filling has cracked.
  • You begin to experience tooth sensitivity that lasts several weeks.
  • Your filling is still in place but has become very worn down.
