Bits of composite or dental pocelain are formed to mimic the appearance of the outer or facial surface of the tooth. Veneers are often thought of as an exclusively asthetic treatment option, but this isn't the whole story. While their application does improve the patients smile, there are a number of other reasons why veneers are used in the world of dentistry. These include worn down, chipped or broken teeth which interfere with proper occlusion. Gaps or spaces between teeth as well as misalignment of teeth can also be corrected with veneers as long as orthodontic intervention is not required. Discoloration of teeth due to hypo or hyper calcification, excessive floride treatment, and tetracycline use in children are also reasons why patients might seek veneers as their treatment of choice.
