Professional teeth whitening is one of the most popular cosmetic dental treatments there is. Patients across Seion choose it because the shade lift is calibrated to their teeth and sensitivity. Results can appear in a single in-chair session or build gradually over two to three weeks at home.
How Tooth Colour Is Measured
The VITA guide gives whitening an objective before-and-after in Seion: most teeth start near A2–B3, and a course commonly achieves a 4–8 shade improvement.
Response depends on the cause of the staining — surface and yellow discolouration whiten well, developmental and grey staining resist it, and any crowns or composite won't shift, so mismatches are worth discussing first.
Teeth Whitening in Seion — Local Context
Expect in-chair whitening in Seion to cost £300–£700, with take-home tray kits typically £200–£450.

Professional whitening is legally restricted to registered dental professionals in the UK. Always verify that any clinic offering whitening treatment is registered with the General Dental Council before proceeding.
Tooth Sensitivity and Aftercare
Sensitivity is the most common side effect — usually a sharp, transient twinge with air or cold that settles within 24–48 hours. A sensitivity toothpaste used for two weeks beforehand noticeably reduces it.
For 48 hours afterwards, avoid intensely pigmented foods and drinks — coffee, tea, red wine, berries, tomato sauces — while the enamel is temporarily more porous. Results typically last 12–24 months before a short top-up restores the shade.
