How to Tell When Your Dental Filling Needs Replacing
Springville, N.Y. – September 19, 2026 -- Adults with aging dental fillings can watch for cracks, sensitivity, and rough edges to catch problems before they require a root canal or crown, according to insights from Dr. Amy E. Schmitt-Kingston of Springville, New York, featured in a HelloNation article.
Dental fillings restore teeth and stop cavity progression, but their lifespan varies by material, size, and daily habits. Metal amalgam fillings typically last ten to fifteen years, while composite resin fillings last five to ten years.
Fillings can crack or separate from the tooth over time
As restorations age, they may chip, crack, or pull away slightly from the natural tooth. Small gaps that form in this process let bacteria in, allowing decay to develop beneath the surface where it isn't visible to the patient.
