Why a crown instead of just a new filling?

Each time a filling is replaced, more tooth structure is removed. At some point, a crown provides better protection than repeatedly replacing fillings.

Old Failing Filling

Replace failing fillings with lasting crowns

What is old failing filling?

Fillings don't last forever. Old amalgam or composite fillings can crack, leak, or fall out, allowing decay to form underneath. When a filling fails, a crown often provides better long-term protection.

Why should you treat it now?

Failing fillings allow bacteria under the tooth surface. The longer you wait, the more decay can spread, potentially requiring root canal or extraction.
