Teeth Whitening

Professional teeth whitening lightens the natural shade of the teeth using a controlled peroxide gel. Dental Clinic Jankowscy offers both in-office light-activated whitening, done in a single visit, and a take-home tray system with custom-made trays you use over a couple of weeks. Both are supervised by the dental team, which protects the gums and checks suitability beforehand for a safer, more even result than over-the-counter kits.

Professional whitening uses a peroxide-based gel to break down staining within the enamel and dentine and lift the overall shade of the teeth by several levels. Because it is carried out or supervised by the dental team, the concentration, gum protection and number of applications are controlled, which generally gives a more even and predictable result than shop-bought strips or kits — and lets the clinic check first that the teeth and gums are healthy. Dental Clinic Jankowscy offers two routes. In-office whitening is completed in a single appointment: the gums are isolated, a stronger gel is applied to the teeth and activated, usually with a light or laser, in repeated cycles during the visit. The take-home option uses custom-made trays and a milder gel that you wear at home for a set time over roughly two weeks, which many people find gentler and easy to top up later. The clinic usually recommends a professional clean beforehand so the whitening acts on the natural tooth surface. Temporary tooth sensitivity is the most common side effect and settles after treatment. Whitening works on natural teeth only — it does not change the colour of fillings, crowns or veneers, which may need replacing to match a new shade — and it is not carried out during pregnancy or breastfeeding. Suitability, expected results and aftercare are explained at consultation.
