Composite fillings are a great tooth-colored filling option, but they’re not foolproof. Composite fillings can last for many years, but they are likely to need to be replaced at some point.

Now a new study gives us a thorough breakdown of the possible causes of composite filling failure.

Why Composite Fillings Fail

According to a recent study in the Australian Dental Journal, about 13% of composite restorations fail. That’s based on a meta-analysis of studies published from 2006 to 2016 that focused on composite restorations. The data included a total of 4300 restorations, of which 568 failed.

The most common causes of restoration failure were:

  • Restoration fracture 39%
  • Secondary caries 26%
  • Tooth fracture 24%

These three causes of failure accounted for about 90% of all composite filling failures. Remarkably, postoperative sensitivity or pain was not a significant cause of restoration failure. Less than 1% of composite fillings failed because they caused discomfort. That’s a large improvement over the previous decade, when nearly 12% of restoration failures were caused by tooth sensitivity.

A Better Approach to Tooth-Colored Fillings

So what do you do if you are unhappy with the failure rate of composite fillings? Do you have to go back to metal amalgam? Not at all. We have another approach to tooth-colored fillings that can give you much better-lasting results.

With our CEREC system, we can create ceramic inlays and onlays. These fillings are very strong and very durable. In studies, they have shown that they have the lowest failure rate of any restoration, including metal amalgam and gold.

Much of the secret is in their strength. CEREC restorations are almost as tough as diamonds. With nearly two-thirds of filling failures related to fracture of either the restoration or the tooth, the strength of CEREC inlays and onlays is a major asset.

And CEREC fillings aren’t just strong: they’re beautiful, too. The luster of the ceramic material is the closest we can achieve to natural tooth enamel. It’s much more natural in appearance than composite fillings.

The CEREC system is a much better approach to inlays and onlays than we used in the past. Instead of having to send away to a lab to get your inlays, we can make them while you wait!

With strength, beauty, and convenience, CEREC is a great approach to restoring your teeth.
