Professional whitening is dosed and timed by the dentist, unlike home strips. The aim is a lighter shade without harming enamel. Veneers and crowns do not bleach; their colour is planned separately.
Short-term sensitivity and colour settling are normal. Staining food and drink are limited for the first 48 hours.
Whitening is not a substitute for smile design on its own. If shape or a chipped edge is the issue, it is planned with veneers.
