What Are Porcelain Veneers?
Porcelain veneers are thin shells of medical-grade ceramic that are attached to the front surfaces of teeth to enhance their appearance. They are custom-made for each patient and are designed to look like natural tooth enamel while providing strength and resilience comparable to natural tooth structure. Veneers are often used to rectify a variety of dental issues, including stained, chipped, misaligned, uneven, or abnormally spaced teeth. The process of applying veneers involves removing a small amount of the tooth's surface to accommodate the shell, ensuring a seamless fit and a natural look. Porcelain veneers are popular in cosmetic dentistry due to their ability to provide an immediate transformation to one’s smile, offering a durable and aesthetically pleasing solution.
Material Types Used to Make Veneers
Each type of material used to make a veneer has its own specific applications, advantages, and considerations, and the best choice varies depending on the individual's dental needs, aesthetic goals, and budget.
Composite Resin Veneers
Made from a tooth-colored resin material, composite veneers can be sculpted directly onto the teeth. They are less expensive than porcelain and require less tooth enamel removal, but they may not last as long and can be prone to staining. Because the material is directly applied to the tooth chairside, it is typically a 1 visit procedure.
Feldspathic Veneers
Made from layered feldspathic porcelain by skilled ceramic artisans. They are customizable because of the layering of the porcelain powders and have a high esthetic value. The material has high translucency and is optically very close to natural teeth. However, they are not as strong as pressed or milled ceramic porcelain. But with modern advanced bonding agents, strength can be increased with strong bonds to the enamel.
Lumineers®
A brand of ultra-thin porcelain veneers, Lumineers are known for being about as thin as a contact lens, requiring minimal to no tooth reduction. They are durable and can be an option for those who wish to avoid extensive dental work. However, there are limited situations where they are a healthy fit as they are placed directly over existing tooth structures at the gum tissue level. This can cause gum tissue inflammation and periodontal problems if they are over-contoured with unnatural emergence profiles, which is a description of how the veneer seats under the gum and the contour the veneer has by the gum line.
Zirconia or Lithium Disilicate Veneers
Developed to address situations where feldspathic veneers will not be strong enough. Made from strong pressable or milled ceramic material, these veneers are ideal for patients with teeth that have significant damage or decay with strong biting forces. They provide excellent strength and are resistant to wear and staining. Drawbacks to these include the need for surface stain and glazing to build in esthetics and reduce their monochromatic look which tends to lower the optical value of the restoration. There is also the need for more aggressive tooth preparation to be able to add esthetics with possible layering over the monochromatic base.
Problems Addressed by Porcelain Veneers
Porcelain veneers are a versatile cosmetic solution, effectively addressing a range of dental issues:
- Discoloration: Veneers can cover stains and discoloration that teeth whitening procedures cannot remove, including stains from medications, excessive fluoride, or root canal treatments.
- Chips and Cracks: Minor chips and cracks in the teeth can be concealed with veneers, restoring a smooth and unblemished appearance to your smile.
- Gaps and Spacing: Veneers can close gaps between teeth, providing a more uniform and evenly spaced smile without the need for orthodontic treatments.
- Misalignment and Irregular Shape: For teeth that are slightly misaligned, uneven, or irregularly shaped, veneers offer a cosmetic solution to create a more harmonious look without extensive orthodontic procedures.
- Wear and Tear: Natural wear of teeth from grinding (bruxism) or age can be corrected with veneers, restoring the original contour and functionality of the teeth.
- Size Discrepancies: Veneers can alter the size of teeth that are too small or disproportionate, achieving a balanced and proportionate smile.
