Since they require approximately .5mm of tooth reduction, porcelain veneers are NOT considered a reversible form of treatment. Occasionally the preparation of a Porcelain Laminate Veneer does not necessitate the use of a local anesthetic. However, for those patients that are particularly sensitive or anxious, a local anesthetic is advisable.
The laboratory time required for the fabrication of a Porcelain Laminate Veneer is approximately one week. Due to the minimal amount of tooth reduction, it is usually not necessary to fabricate any type of temporary restoration. Should a temporary be needed, they can, in most circumstances, be made at the time of treatment.
Between your preparation visit and the insertion visit, you can expect some sensitivity to hot and cold. This is normal and is due to the removal of a small portion of the enamel covering of the tooth. This sensitivity should disappear after the placement of your Porcelain Laminate Veneer.
Your second visit, the insertion of your laminate, can be accomplished, once again, with or without local anesthetic. This visit is usually longer in length. The laminates are placed with a light sensitive resin which is hardened by using a white light.
Once placed your laminates are very strong and will resist most of the forces placed upon them by a normal diet. Porcelain has great crushing strength but poor tensile strength. Therefore, you should avoid anything that will tend to twist the laminate.
