For health of young teeth, avoid traditional veneers on teenagers and go for Prepless Veneers. If veneers are placed when a young patient is still growing, there are chances they will need to be replaced for maximum esthetics after a growth spurt. Theoretically, someone could get veneers at 14, replace them at 18 and again at 22. To minimize such cost, a safe bet is 18 years of age for females and 20 for males.
