How long does a dental filling last?

 
 

Dental fillings vary widely in durability depending on three things: the material of the filling, the dental hygiene of the person with a filling, and the preventative steps followed to increase filling longevity.

If you want your dental fillings to last, a more expensive material might be worthwhile. Gold is one of the popular options because of its strength, despite its cost. 

The following is a list of common filling materials with their approximate years of longevity:

  • Composite Resin: 7-10 years

  • Porcelain: about 15 years

  • Silver Amalgam: 10-15 years

  • Gold: 10-30 years (usually at least 20)

The reasons that everyone does not choose gold vary from style to expense. This list can provide insight into the level of durability you need.

You might have noticed that longevity amongst each material varies quite a bit. The dental hygiene of an individual can play a role in how long their filling lasts.

To properly care for your dental fillings, follow general dental hygiene tips:

  • Brush teeth twice a day

  • Floss daily

  • Follow specific dental advice

In addition to proper care, you can also take preventative steps with eating to avoid damage to fillings. Avoid eating the following foods (or eat them in small amounts very rarely):

  • Excess sugar (can cause cavities)

  • Hard foods

  • Exceptionally sticky foods

Even following these steps and choosing the most durable filling material does not guarantee the longest possible lifespan for your filling. Your mouth is unique. To know what is best for you and your teeth, visit a dentist at Cascade Dental Care and discuss your options.
