Temporization, in the context of cosmetic dentistry, is the process of fitting temporary restorations over teeth that have been prepared for porcelain veneers. This phase bridges the time between the initial tooth shaping appointment and the final placement of the custom permanent veneers. These interim covers are a standard part of the overall treatment plan. They are placed to protect the underlying tooth structure and maintain the appearance of the smile while the dental laboratory completes its work.
Why Temporary Veneers Are Necessary
Temporary veneers serve several practical functions beyond simply acting as placeholders. A primary role is to shield the prepared tooth surfaces, which have had a thin layer of enamel removed to accommodate the permanent veneers. This removal leaves the underlying dentin vulnerable, so the temporaries prevent hypersensitivity to temperature changes and protect against bacterial invasion and physical trauma.
The provisionals also maintain the patient’s oral function and aesthetics, which is especially important for teeth visible when speaking or smiling. This interim stage functions as a “test drive,” allowing the patient and dentist to evaluate the proposed changes in tooth shape, length, and bite alignment before the final porcelain restorations are made. Any necessary adjustments to the aesthetic design can be communicated to the lab based on this real-world assessment.
The Technique for Creating and Placing Provisionals
The process for creating temporary veneers often begins with a pre-operative mold, or matrix, that captures the desired final tooth shape. The dentist fills this clear matrix with a temporary restorative material, such as an acrylic or bis-acryl composite resin. This material is seated directly over the prepared teeth and allowed to set, quickly taking on the pre-planned shape.
Once the resin has cured, the matrix is removed, leaving the temporary restorations bonded to the teeth. The dentist then carefully shapes, contours, and polishes the provisionals to ensure smooth margins that do not irritate the gum tissue. Retention is achieved using spot-bonding, where a small area is lightly etched and a weak, non-eugenol temporary cement is applied. This method provides sufficient hold against normal chewing forces but allows for easy removal without damaging the prepared tooth surface at the final appointment.
Essential Care and Maintenance Instructions
Maintaining the temporary veneers requires conscious modification of daily habits to prevent dislodgement or fracture. Patients must strictly avoid sticky foods like taffy or chewing gum, which can pull the temporaries off the teeth. Hard or crunchy items, such as nuts, ice, or hard candy, should also be avoided as they can chip or break the brittle resin material.
Chewing should be focused on the back teeth, and patients should avoid biting directly into hard foods with the temporaries. Oral hygiene must continue using a soft-bristled toothbrush and non-abrasive toothpaste. Flossing requires a specific modification: instead of pulling the floss up or snapping it out, which can lift the temporary, the floss should be pulled through the contact point from the side.
Dealing with Common Temporary Issues
Despite careful maintenance, issues like a temporary veneer loosening or falling off can occur, requiring immediate attention to protect the underlying tooth. If a temporary restoration becomes loose or detached, the patient should save the piece and contact the dental office immediately to schedule an emergency recementation. The exposed tooth is highly sensitive and susceptible to shifting or decay, so it must be covered quickly.
Patients should not attempt to reattach the temporary using household adhesives, which can damage the tooth surface and interfere with the final bonding process. If a sharp edge or rough spot develops, dental wax can be placed over the area to prevent irritation. Persistent pain, swelling, or sensitivity that lasts more than a few days should prompt a call to the dental team for a professional evaluation.
