Provisional crowns and fixed bridges are used to protect the teeth and to provide a satisfactory appearance while the new permanent crown(s) and fixed bridge(s) are being fabricated. A provisional restoration is usually made of acrylic resin, which is not as strong as the final porcelain/metal restoration. A provisional is attached to the teeth with temporary cement; therefore, it is important to minimize the chewing pressure on a provisional restoration since it can fracture and/or become dislodged. If this does occur, call our office as soon as possible for repair or recementation. Waiting more than a few days can create unnecessary problems and may delay your treatment.
