Tooth filling procedures involve removing the decayed section of a tooth and replacing the area with porcelain or silver amalgam. This treatment stops cavities from growing, enhances the strength and structure of your teeth, and may even improve tooth color. However, the fillings will wear out over time. So if you've been relying on dental fillings for biting function and tooth protection for several years, here are a few signs they may need to be replaced.

How to Tell if Your Dental Filling Requires Replacement 

1. Frequent Toothache

If you experience discomfort when drinking hot or cold liquids or have tooth pain in general, it's a sign that the filling is deteriorating. A hole in the dental filling exposes nerve endings that are extremely sensitive when chewing. In addition, food particles trapped behind a broken filling can create a new cavity and inflame the dental pulp, causing more significant discomfort.

2. Obvious Damage

A discolored or broken dental amalgam may cause discomfort even with a soft touch. Check in the mirror or use your tongue to feel for gaps in fillings on your posterior teeth. If there's a visible crack, consider getting a new tooth filling to prevent cavities from worsening. However, if unsure of what to look for, visit your dentist for a professional opinion.

3. Lifespan

A dental filling can last anywhere from five to ten years, depending on the material and oral hygiene. Metal amalgams can last up to fifteen years before they must be replaced. Consult your dentist if your dental fillings show noticeable degradation but haven't yet reached the end of their expected lifespan.
