Short answer: Tooth whitening works best when it is dentist-supervised, planned around sensitivity risk and matched to realistic expectations.
Why assessment comes first
Sensitivity, gum problems, decay, cracks and leaking restorations can change what is safe or realistic. Whitening should not be started on an untreated dental problem.
Professional whitening and safety
Professional whitening starts with an assessment because sensitivity, gum problems, decay and existing restorations can change what is safe or realistic. Whitening gels work on natural tooth structure, not crowns, veneers, bonding or fillings.
What results to expect
Shade change varies between patients. The aim is a cleaner, brighter smile that still suits your tooth type and complexion, not an artificial target shade.
Managing sensitivity
Sensitivity is usually temporary but should be planned for. Your dentist may adjust the whitening schedule, gel strength or toothpaste advice if you are prone to discomfort.
Whitening before other cosmetic work
If you are considering bonding, veneers or crowns, whitening may need to happen first so new restorations can be matched to the final shade.
