Did you know? Dental fillings typically have a 10-year lifespan. For most patients who have experienced a serious toothache or needed a root canal and crown, the cause is an old silver mercury filling that, in time, has caused the tooth to crack. From the day a silver filling was placed, it began to expand and contract with heat and cold. The filling slowly leaks and corrodes at the edges, and can even cause a fracture in the tooth. Many of our patients prefer to replace with silver fillings before the situation gets to the point of pain or a broken tooth. If you have concerns about your old silver fillings, we can help with a no-charge appointment to make a plan to help you avoid future toothaches and dental emergencies.
