In-clinic versus at-home whitening
Whitening is the simplest cosmetic treatment and the one most often done badly. In the clinic, under supervision, it lifts the natural shade of your enamel by several tones in one visit without damaging it. Unregulated products cause sensitivity and patchy results. The difference is not only speed but safety.
What does whitening actually work on?
Whitening works only on natural tooth structure. Veneers, crowns and fillings do not change colour, and stains from inside the tooth (after a root canal, for example) need a different approach. That is why the examination comes first — you are told which category you are in before anything is booked.
How the session works
Examination and cleaning first (whitening over tartar gives uneven results), then gum protection, then the whitening gel activated in the clinic over three to four short cycles in a visit of about an hour. Your shade is recorded before and after, with advice for keeping it.
How long do results last?
Usually from many months to a couple of years depending on habits (coffee, tea, smoking), and they can be topped up. Mild sensitivity for 24 to 48 hours is normal and passes; avoid strongly coloured food and drink for the first two days.
A tip before veneers
If you are planning veneers or a smile design, whiten your natural teeth first so the restorations are matched to the new shade. The aim is always a natural, bright shade that suits your face, not an artificial white.
Frequently asked questions
Does whitening damage enamel? Supervised in-clinic whitening does not damage enamel; problems come from overusing unregulated products.
