Porcelain veneer placement follows a two-appointment protocol. At the first appointment, the dentist removes a thin layer of enamel from the facial surface of each tooth to be treated — typically 0.3 to 0.7 mm — to create space for the veneer shell and prevent the restoration from appearing bulky. Impressions or intraoral scans are then taken and sent to a dental laboratory, where the veneers are custom-fabricated over approximately one to two weeks. Temporary veneers are usually fitted to protect the prepared teeth in the interim. At the second appointment, the temporary restorations are removed, the permanent veneers are tried in for fit and shade assessment, and then bonded with resin cement following acid etching and surface conditioning.
Candidacy is based on adequate enamel thickness (preparation into dentine is associated with higher sensitivity and lower bond longevity), the absence of active periodontal disease, and realistic patient expectations regarding achievable shade and shape. Significant bite abnormalities or parafunctional habits such as bruxism substantially increase the risk of fracture and are relative contraindications. Composite veneers can be completed in a single appointment and require less or no tooth preparation, but are less durable and more prone to staining than laboratory-fabricated porcelain restorations.
Recovery is minimal; post-operative sensitivity typically resolves within a few days. Porcelain veneers have an average clinical lifespan of ten to fifteen years, after which they will require replacement. Patients should be counselled that the procedure is irreversible: once enamel has been removed, the teeth will always require some form of coverage.
