No. Veneers are only one route to a smile makeover. Some cases are better treated with whitening, bonding, orthodontics, gum treatment, replacement of old restorations, or reshaping of small chips.
A responsible cosmetic plan starts with diagnosis. If veneers are recommended, the dentist will explain why they are more suitable than simpler options, how many teeth are involved, and how the bite and tooth structure will be protected.
