Whitening lightens natural teeth and keeps your enamel. It suits healthy teeth with yellowish staining. Veneers cover the front of the tooth to change its colour, shape or length. They suit staining that whitening cannot shift, or chipped, worn or uneven teeth.
Many smile plans use both: whitening first, then veneers matched to the brighter shade.
Patients often come in asking for one when the other would suit them better. Someone who only wants brighter teeth may not need veneers at all. Someone with chipped, worn edges may be disappointed by whitening alone. The right answer depends on what you would like to change.
