Teeth Whitening (Take-Home Trays)

A professional whitening treatment that lightens teeth discoloured by age, food, drink or staining habits using custom trays you wear at home. The dentist takes impressions to make trays that fit precisely, then supplies professional whitening gel and instructions for safe, gradual lightening. In-chair laser whitening and internal whitening of a single dark tooth are also available.

Professional teeth whitening lightens the natural shade of the teeth using a controlled peroxide-based gel, reversing discolouration that builds up over time from food, drink, smoking and ageing. At Leśnickie Centrum Stomatologiczne the take-home approach begins with impressions to create custom-fitted trays; you then wear the trays with professional-strength gel for a set period each day over a couple of weeks, allowing the colour to lighten gradually and evenly under the dentist's guidance. Because the trays are tailored to your teeth, the gel is kept where it is needed and contact with the gums is minimised. The clinic offers established systems — Opalescence and Vivida — for tray whitening, as well as an in-chair laser whitening option for those who prefer a single-session treatment at the practice. A separate internal whitening technique is available for a single tooth that has darkened after root canal treatment, working from the inside to match it back to its neighbours. Whitening works best on clean teeth, so a hygiene appointment beforehand is often recommended, and it lightens natural tooth structure only — existing fillings, crowns or veneers do not change colour, which the dentist will take into account when planning. Some temporary sensitivity during a whitening course is common and usually settles afterwards. Results vary between individuals and are not permanent; avoiding strongly staining habits and occasional top-ups are associated with maintaining the effect for longer.
