How teeth whitening works
Tooth colour comes from two layers. The outer enamel picks up surface stains from what we eat and drink, and the dentine underneath naturally darkens and yellows with age. Whitening gels contain a peroxide that passes through the enamel and breaks down the coloured molecules inside the tooth, so the whole tooth looks lighter rather than just cleaner on the surface.
Not every stain responds the same way. Yellow and brown tones usually lighten well. Grey staining from certain medicines, white spots or a single tooth darkened after an injury or root canal may need a different approach, which we will explain at your first visit.
In-clinic or take-home whitening?
In-clinic whitening is done in one appointment. We place a barrier over your gums, apply a stronger gel in timed rounds and check the shade as we go. It suits people who want a visible change quickly, for example before a wedding.
Take-home whitening uses custom trays made from a 3D digital scan of your teeth and a milder gel you wear for a set time each day, usually over one to two weeks. The change is gradual and easy to control, and the same trays can be used for top-ups later.
Your dentist will suggest one or a combination, based on your shade, how sensitive your teeth are and how much time you have.
A natural shade, not an unnatural white
A good result looks like your own teeth on a bright day. We aim for a shade that suits your skin tone and the whites of your eyes, rather than a flat, opaque white that can look artificial. We record your starting shade, agree a target together and stop when you are happy. If you would like more than whitening can offer, a fuller smile design or dental veneers may be worth discussing.
