A crown replaces the weakened or defective tooth structure with a stronger material. Traditional crowns are normally completed in two visits. Our in-house CEREC® one-day crown system can prepare, fabricate, and deliver your crown in a single appointment. From start to finish, the process typically takes just two hours. CEREC software also allows Dr. Kottman to design a crown that fits precisely, feels like your natural tooth, and is metal-free.
