What Should I Do If My Filling Becomes Loose? A Complete Guide!

Not exactly. While amalgam (silver) fillings have been used for decades, they have a few downsides. Metal fillings can expand and contract with temperature changes, causing cracks in your tooth over time. They also contain mercury and are more visible when you smile.

Our office uses composite resin fillings, which are safer and more advanced. They are mercury-free, blend naturally with your tooth color, and don’t react to hot or cold foods. They’re also versatile, making them ideal for both front and back teeth. For most patients, they’re a more comfortable and aesthetic solution that supports long-term oral health.

Although rare, dental fillings can become loose. Possible reasons include: 

• Normal wear and tear: Chewing pressure and time can gradually weaken older fillings.
• Tooth decay: New decay under or around the filling can loosen the bond.
• Fractured tooth: If part of the tooth breaks, the filling may lose its support.
• Improper bite pressure: If a filling is too high, it can cause extra stress and eventually loosen.
• High bite pressure for patients who grind or clench their teeth.

While a filling will eventually need replacement, good maintenance can extend its longevity. Observe good oral hygiene and visit your dentist regularly for cleanings and check-ups. Avoid using your teeth as tools and consider a custom nightguard if you grind your teeth at night.
