Does a Tooth Filling Last Forever?

A tooth filling, also known as a dental filling, is one of the most popular ways to restore teeth that are in bad shape due to decay, injury, or imperfections. They have been the standard for rebuilding teeth for as long as dentistry has existed. The procedure of placing a tooth filling is simple, quick, and very beneficial to the health of the oral cavity. When considering dental restorations, it is a good idea to become familiar with the lifespan of each option. This allows patients to make an educated decision on which option is most suitable for them.

The average lifespan of a tooth filling

Tooth fillings can last anywhere from five to 30 years. However, on average, they last about 15 years. While the restoration is intended to be a permanent restoration, it is hard to ensure that due to everyday wear and tear in the mouth. Wear and tear occur over time as a result of eating and teeth grinding (bruxism).

What is important to know is that the lifespan of a tooth filling relies heavily on the type of material used. For example, gold tooth fillings are said to last the longest (about 15 to 30 years) as the material is strong and very reliable. However, composite resin tooth fillings may not last more than 5-7 years as the material is often used for temporary purposes. That said, the most common tooth filling material is porcelain, which is a good in-between. It offers a natural appearance while lasting about 10 to 15 years on average.

How to make tooth fillings last longer

Tooth fillings are much more likely to last longer if the oral cavity is maintained carefully and properly. Outlined below are a few tips from a general dentist on how to make a tooth filling last:

• Brush twice a day or after every meal to remove food debris and plaque build-up
• Floss once a day as this eliminates build-up between the teeth, which could cause infections in a filled tooth
• Rinse the mouth a few times a week with salt water or mouthwash to reduce accumulate bacteria
• Avoid hard, tough, or sticky foods that could damage the tooth filling, particularly when the dentist first places it
• See the dentist on a regular basis so that the filled tooth can be monitored

When it is time to replace a tooth filling 

Even the best oral hygiene routine cannot prevent everyday wear and tear. Fillings can wear down over time because they are not as strong as natural tooth enamel. Bacteria can enter the tooth through worn fillings, which can lead to further decay and damage. Patients should call the dentist to replace a willing if they experience the following:

• Persistent pain, particularly when chewing food
• Yellow, gray, or brown discoloration
• Visible cracks or chips
• Bad breath or taste in mouth
• Difficulty flossing
• Changes in bite alignment
