Whitening lightens natural tooth structure. It does not change crowns, veneers, or fillings — which is why sequence matters if you have existing dental work at the front.
If restorations are planned for front teeth, whitening usually comes first so the new work can be matched to the lighter shade. Doing it the other way round means restorations that no longer match.
Sensitivity during whitening is common and usually temporary. Spacing sessions, shorter wear times, and desensitising products help. Existing decay or exposed root surfaces should be treated before whitening, not during.
A page can inform you. It cannot examine you.
A quick exam before whitening avoids the two common disappointments: unmatched restorations and unexpected sensitivity.
