Abstract
Ceramic laminate veneers are widely recognized in aesthetic dentistry for their lifelike appearance, favorable mechanical behavior, and the ability to improve a patient’s smile with minimal removal of tooth structure. Their reliable bonding protocols and long-term clinical performance have made them a preferred option for many restorative and cosmetic treatments. Nevertheless, situations such as functional failure, esthetic concerns, chipping, secondary caries, or the need for design modifications may require the removal of an existing veneer. Detaching a bonded veneer, however, is often difficult when using traditional rotary instruments. The strong adhesion between the ceramic, resin cement, and enamel can make controlled removal challenging, increasing the risk of overheating, excessive enamel loss, and accidental damage to surrounding tissues. In response to these limitations, laser-assisted debonding has gained attention as a more conservative and predictable method for veneer removal. Specific laser wavelengths—especially those in the erbium family—can interact with the underlying resin cement by promoting thermal softening or micro-ablation without significantly affecting the ceramic structure or the tooth itself. This selective interaction weakens the adhesive interface, allowing veneers to be detached with less force and greater precision. Clinical studies have shown that laser-assisted techniques can shorten treatment time, enhance patient comfort, and substantially reduce the likelihood of enamel damage compared with mechanical removal. This narrative review discusses the development of laser technologies relevant to veneer debonding, the scientific principles behind laser interactions with dental materials and tissues, and the available clinical evidence supporting their use in modern restorative practice.
