Clinical Outcome
Multiple porcelain crowns and veneers were placed over several appointments to replace failing restorations and improve smile aesthetics. Replacing old crowns eliminated dark gingival appearance and restored natural tooth colour.
Individual responses to extensive crown and veneer treatment vary significantly. Treatment outcomes cannot be guaranteed. Porcelain restorations can chip, fracture or debond over time. Typical longevity ranges from 10-15 years though outcomes vary considerably.
