Losing a dental filling can feel alarming, especially if it happens suddenly while eating or brushing your teeth. Fillings are designed to restore and protect teeth that have been affected by decay, but they don’t last forever. Over time, normal wear and tear, chewing pressure, or even biting into something hard or sticky can cause a filling to loosen or fall out.

When this happens, the inner part of your tooth may be exposed, which can lead to sensitivity, discomfort, and a higher risk of further damage if not addressed quickly.
