Professional whitening uses a peroxide gel to break down the stain molecules held inside enamel and dentine. It lightens your own teeth; it does not change ceramic, composite or any existing restoration.

What whitening can and cannot lift

It works well on staining from coffee, tea, red wine, tobacco and age. It works poorly or not at all on tetracycline banding, fluorosis patches, and the grey of a single dead tooth — that last one needs internal bleaching, which is a different procedure done through the back of the tooth.

Combining the two — one in-clinic session followed by trays — gives the most stable result, because the trays let you top up later without another appointment.

The sequencing that people get wrong

Whiten before any ceramic work, never after. Veneers and crowns are matched to whatever shade your natural teeth are on the day the colour is chosen. Whiten afterwards and your natural teeth lighten while the ceramic stays exactly where it was — leaving a mismatch that can only be fixed by remaking the ceramic.

Leave two weeks between finishing whitening and choosing a shade. The colour rebounds slightly and then settles; matching to the rebounded shade is what keeps it looking right a year later.

Cost and how long it holds

Prices for an in-clinic session change with our current offers, so message us for an up-to-date quote. Expect the result to hold one to three years, depending almost entirely on what you drink and whether you smoke. Top-up trays extend it indefinitely at low cost.

Sensitivity, honestly

Some sensitivity during and shortly after treatment is common and normal — sharp, brief, triggered by cold. It settles within a day or two. A desensitising gel applied at the end reduces it substantially. If you already have sensitive teeth, tell us before rather than after; we lower the concentration and lengthen the schedule.

Common questions

Does whitening damage enamel?

Professionally supervised whitening at controlled concentrations does not damage enamel. The risks come from unsupervised high-strength products and from repeating treatment too often, which is why we set an interval rather than whitening on demand.

Will my crowns and fillings whiten too?

No. Ceramic and composite hold their colour, so existing restorations stay exactly as they are. If you have visible crowns or bonding on front teeth, whitening the natural teeth around them will make them stand out — plan the sequence with us first.

How white will my teeth actually go?

Usually several shades on the standard guide, but the ceiling is set by your own enamel. We show you the realistic end point on a shade guide before starting rather than promising a number.

Can I whiten if I have gum recession?

With care. Exposed root surfaces are dentine, not enamel: they whiten less and are more sensitive. We shield those areas and often prefer the gentler take-home route in these cases.

How soon before a wedding or event?

Finish at least two weeks before. That covers the shade rebound and gives room to repeat a session if the result is not even.
