The Virginia Dental Association and its members abide by a strong Code of Ethics that was written to protect the public.  Our member dentists deliver crowns to their patients intending to have these restorations last much longer that 5 years.  Unfortunately, diet, poor dental hygiene, medications, and lack of saliva are some of the predisposing factors that lead not only to crown failures but other dental treatment as well.  To target crowns or any other dental procedures for warranty periods is simply ill founded.  The overwhelming majority of dentists take pride in their ability to privide quality dental care to their patients.  Adding additional regulations in the form of warranties would be burdensome to dental practitioners, impossible to monitor and completely unnecessary.
