A small cavity may look harmless on the surface, but decay can continue spreading through the softer inner layers of the tooth.
If left untreated, it can eventually reach the pulp—the living center of the tooth that contains nerves and blood vessels. At that stage, treatment often becomes more complex than a simple filling.
This is why dentists recommend treating cavities early, even when they are small and painless. Early intervention helps preserve more of the natural tooth and can prevent deeper damage over time.
