Tea, coffee, tobacco and age-related changes can make a smile appear darker. The appropriate method depends on the type of discolouration and the health of the teeth and gums.
Fillings, crowns, veneers and implant crowns do not change colour with whitening gel. Visible restorations may require separate shade planning.
Suitability
Who may benefit from an assessment?
- People who want to lighten the shade of natural teeth
- Patients with surface stains from tea, coffee or tobacco
- People seeking a dentist-supervised plan before an event
- Patients willing to have decay and gum health checked first
Which methods are available?
In-office whitening is applied under dental supervision. Dentist-supervised home whitening uses custom trays and a prescribed gel. A combined approach may suit some cases.
Why is an examination needed?
Decay, cracks, exposed roots, gum disease and existing sensitivity should be assessed first. One dark tooth can have a different cause, including trauma or loss of vitality.
Can whitening cause sensitivity?
Temporary tooth sensitivity and gum irritation can occur. Gel strength, duration and sensitivity control are adjusted individually; severe pain should not be ignored.
How can the result be maintained?
Good oral care and limiting staining habits can support the result. Shade may darken again over time, so repeated treatment should be discussed with a dentist rather than used excessively.
