Porcelain restorations are the happy medium of color and strength. Placing porcelain usually involves two appointments. The first appointment is to remove the decay, prepare the inlay or onlay restoration and take an impression or scan. The dental laboratory fabricates a custom porcelain restoration that is bonded in place at the second appointment. Current porcelain restorations are very strong, have good color and hold up well to wear. Porcelain restorations have a higher fee than composite (plastic) fillings but will last much longer in most cases.
