Most patients don’t realize their old fillings are slowly working against them.
Every filling has an edge — the margin where restoration meets tooth. Over time, that seal breaks down. Bacteria get underneath. Decay starts growing in a place you can’t see and can’t feel until it’s already done real damage.
That’s marginal leakage. And it’s one of the most common reasons old fillings eventually need to be replaced.
Biomimetic restorations bond differently. They’re designed to seal and flex with the tooth instead of pulling away from it. The goal is a margin that holds — not for a few years, but for the long run.
