How Long Does a Tooth Filling Last?

How Long Does a Tooth Filling Last?

A tooth filling is used to repair a decayed region of the tooth. It prevents it from spreading and restores the strength of the tooth. A filling will last for several years, but it will not last indefinitely. Here's how long you can expect your restoration to last, depending on the type:

Amalgam Fillings Mixtures of metals are the most conventional fillings. Amalgam fillings are long-lasting and effective, which is why they've been around for over a century. A metal filling should last about 15 years on average before needing to be replaced, although this can vary depending on factors such as grinding or clinging your teeth.

Composite Fillings A blend of fine glass and plastic particles is used to make tooth-colored fillings.

They're made to match your teeth so they don't stand out when you smile. They are durable despite not being constructed of metal. They usually last between 10 and 12 years before they need to be changed.

Why Does My Filling Need to Be Replaced?

Your filling may need to be updated for a variety of reasons over time. The majority of the time, it is the result of normal wear and tear. Your filling is put under a lot of pressure while you chew. It may break, leak, or fall out over time as a result of this. Bacteria and microscopic food particles can become trapped behind your filling if it no longer protects your teeth as it should. To avoid further degradation, you'll need to get the filling redone.

It's very typical for a composite filling to darken over time. As a result, it has the potential to stand out like a sore thumb. You can have it replaced to guarantee that it blends in perfectly when you smile.
