When cementing either a temporary or permanent crown:
After placing the crown on the tooth, have a wet cotton swab ready to go round the tooth, in order to remove excess cement. After the cement has set for several minutes, take a second wet cotton swab around the margins. Then use an explorer around the margins to remove any remaining cement. Carefully use double knotted floss to go through the contacts to make sure there is no excess cement between the teeth. Make sure you check carefully into the gingival areas.
