Clinical Advantages and Negative Consequences of Dental Veneers: A Review

Abstract

Despite the widespread use of dental veneers within contemporary esthetic dentistry as a restorative treatment option capable of masking imperfections of the dental appearance with little tooth structure loss, there has not been an attempt to identify and evaluate dental veneers within the dental literature along the lines of evidence-based benefits and harms with a clear clinical focus. Clinical benefits of veneers consist of superior aesthetic results, superior tp color stability, optimal tooth form and ideal patient acceptance especially if conservative preparation designs are used in conjunction with contemporary ceramic materials. A classic illustration of the strengths of these materials would be lithium disilicate or feldspathic ceramics; they retain excellent optical properties and demonstrate the best long-term survival when bonded appropriately to enamel. However, dental veneers have their complications. Adverse effects may include irreversible loss of enamel, dentine hypersensitivity, marginal staining, fracture of the ceramic, debonding, and inflammatory reaction of the periodontal tissues, especially in case of inadequate case selection or over-preparation. Based on this, biological risks such as pulp irritation or long-term restorative dependence should also be evaluated, especially in young patients with an intact dentition. Introduction Occlusal overload, parafunctional habits, and inadequate bonding protocols are frequently implicated in mechanical and technical failures of fixed partial dentures (FPDs). Conservative treatment planning, an accurate diagnosis, and a patient-centered approach play an important role in achieving favorable clinical outcomes and preventing adverse effects, as summarized in this review. Dentists need to be mindful of both the pros and cons of dental veneers to ensure reliable esthetic results while still protecting healthy teeth for years to come.
