Why did your composite filling turn gray?

Composite fillings can turn gray due to several factors, including exposure to staining agents like coffee, tea, or tobacco. Over time, wear and tear can also cause the material to lose its luster and appear dull or discolored. Additionally, the bonding agents may degrade or the composite may react to the oral environment, leading to changes in color. Regular dental check-ups can help address these issues before they become more pronounced.
