Studies suggest that dental veneers typically last between 10 and 20 years, but there are cases in which they last longer, explains Legacy Dental. Grinding or clenching of the teeth can cause a veneer to fall off prematurely, so individuals who tend to do so should consider wearing a night guard.Continue Reading
A veneer is a tooth-colored, porcelain or resin shell bonded to the front of a tooth to cover up imperfections, explains WebMD. Some imperfections that veneers can mask include tooth discoloration, gaps, chips, broken teeth, shape irregularities and minor misalignments. Before bonding a veneer, a cosmetic dentist trims about 1/2 millimeter of enamel off of the tooth's surface to make room for the veneer. The trimming process is not usually painful and does not require the patient to receive anesthetic, but anesthetics or sedation are occasionally necessary, notes Legacy Dental.
In dentistry, the most conservative possible treatment is often considered the best option, according to Legacy Dental. Since crowns are a less conservative method of covering tooth imperfections, veneers are usually recommended when they are an option. Conversely, orthodontic treatment is considered a more conservative way to correct misaligned teeth because it does not involve removing enamel, and it is accordingly often recommended above applying veneers to cover up teeth that are out of alignment.Learn more about Dental
