Teeth Whitening

Professional teeth whitening lightens the natural shade of the teeth to remove staining and discolouration built up from food, drinks, tobacco and age. Carried out at the clinic by trained staff, it uses a controlled whitening gel for a result that is faster and more even than over-the-counter products, with the gums protected during treatment. A hygiene appointment beforehand helps the whitening work uniformly. It suits patients wanting a brighter smile without altering the structure of their teeth.

Professional whitening uses a peroxide-based gel to break down the stains and intrinsic discolouration that accumulate in tooth enamel over time, lifting the teeth several shades lighter. Because it is performed under professional supervision, the concentration and contact time are controlled and the gums and lips are protected, which makes it both more effective and safer than shop-bought strips or kits. At Denti Clinic the teeth are first assessed to confirm whitening is appropriate and that there are no untreated cavities or gum problems; a professional clean beforehand is recommended so the gel acts evenly on a plaque-free surface. During treatment the soft tissues are isolated and the whitening gel is applied to the teeth. The result is a brighter, more uniform smile that does not change the shape or structure of the teeth. Some temporary sensitivity to cold is common for a day or two afterward and settles on its own. Results last longest when staining drinks like coffee, tea and red wine are limited and good oral hygiene is maintained, and the shade can be topped up periodically. Whitening works on natural tooth enamel but not on crowns, veneers or fillings, so patients planning visible restorations are usually advised to whiten first and match the new work to the lighter shade. It suits adults wanting a brighter smile with healthy teeth and gums; the dentist confirms suitability at the assessment.
