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.
Professional Whitening Choices in Trethomas
In-chair (laser/light-activated) whitening delivers the fastest visible result — one supervised session with professional-strength gel, most patients leaving 4–8 VITA shades lighter that day.
Take-home tray whitening involves bespoke trays and dentist-supplied gel worn over roughly a fortnight — excellent, controllable results at your own pace.
Combined whitening (an in-chair session followed by take-home top-ups) is often recommended in Trethomas because it maximises the initial jump and lets you maintain the shade over time.
Over-the-counter kits are legally capped at very low peroxide levels and can't match professional results. They suit minor maintenance at best, not a genuine shade change.
Sensitivity, Aftercare and Keeping Results
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.
A brief 'white diet' — skipping strongly coloured food and drink for two days — protects the fresh result. Long-term, good hygiene and an occasional top-up every 12–18 months keep teeth bright.

Will whitening affect my crowns or veneers?
