The short answer: Teeth whitening
Professional teeth whitening uses a regulated peroxide-based gel, prescribed by a dentist, to lighten the natural shade of teeth without removing tooth tissue.

If you are weighing up your options locally, the page on seeing a dentist in Pinner sets out how consultations, written plans and fees work here.

The option described on this page.
Shape after
Composite bonding
Where shape or edges also need changing, bonding is placed after whitening so the shade can be matched.
Position
Invisalign
Whitening changes colour only. Where crowding is also a concern, alignment is planned first.
Ceramic option
Ceramic veneers
Where discolouration is intrinsic and does not respond to whitening, ceramic may be the realistic option.
Suitability is confirmed and the cause of discolouration identified.
Scans are used to make close-fitting trays.
Gel is worn as prescribed over an agreed period.
Shade is checked and any further steps planned.
Shade typically remains stable for one to three years, with periodic top-up whitening.

Common questions
Home whitening kits start from £395 and Enlighten whitening from £595 at this practice. Suitability and the cause of discolouration are assessed before a whitening plan is provided.
Whitening is not carried out where there is untreated decay, active gum disease or leaking fillings, and it is not provided during pregnancy or breastfeeding. Teeth darkened by a single root-treated tooth, or by internal staining, may need a different approach, which is discussed at assessment.
Temporary sensitivity during or shortly after whitening is common and usually resolves within a few days. Tray fit, gel strength, wear time and desensitising products are adjusted to keep sensitivity manageable.
Whitening results commonly last from several months to a couple of years, depending on diet, smoking, hygiene and the original cause of discolouration. Occasional top-up wear with the same trays maintains the shade.
No. Whitening changes natural tooth structure only; crowns, veneers and composite do not lighten. Where restorations are visible, whitening is completed first and the restorations are then matched or replaced to the new shade.
Keep the trays clean and stored dry, continue normal brushing and interdental cleaning, and limit strongly staining drinks such as red wine, coffee and tea in the days immediately after each phase. Routine hygiene appointments and occasional top-up gel help hold the shade.
The common issues are temporary sensitivity and gum irritation, usually from gel overflowing a poorly fitting tray. Results can also look uneven where crowns, veneers or fillings sit alongside natural teeth, because those materials do not lighten. Dentist-prescribed, custom-tray whitening reduces both risks.

Enhance
A smile makeover is a planned combination of treatments — which may include alignment, whitening, bonding, ceramics or gum treatment — sequenced to change the appearance of the smile while protecting long-term dental health.
Restore
A ceramic veneer is a thin, custom-made porcelain facing bonded to the front of a tooth to change its shape, colour or alignment, usually requiring a small amount of enamel to be prepared.
Straighten
Invisalign is a clear aligner system that moves teeth using a sequence of removable, custom-made trays planned from a digital scan of your mouth.
