Take-Home Teeth Whitening (Trays)

Professional tray-based whitening that lightens the natural teeth using custom-fitted trays and dental-grade gel used at home over a short course. At Dentica the trays are made to fit your teeth precisely so the gel stays in contact evenly and away from the gums. For a single dark tooth that has had root canal treatment, the clinic also offers internal (non-vital) whitening to address the discolouration from within.

Tray-based whitening is a professionally supervised way to lighten the colour of the natural teeth. At Dentica impressions or a scan are taken to make custom whitening trays that fit your teeth closely; you then wear the trays with a measured amount of dental-grade whitening gel for set periods over a short course at home. Because the trays are individually made, the gel is held evenly against the teeth and kept away from the gums, which supports comfortable, consistent results compared with generic kits. Whitening works on the natural tooth structure and is most effective on general yellowing or age-related darkening; it does not change the colour of fillings, crowns or veneers, so any visible restorations on front teeth may need to be reviewed afterwards to match a lighter shade. A dental assessment beforehand checks that the teeth and gums are healthy and identifies the cause of any discolouration, since some stains respond better than others. Temporary tooth sensitivity is the most common side effect and usually settles after treatment. For a single tooth that has darkened following root canal treatment, the cause is internal, so the clinic offers non-vital (internal) whitening, which lightens that tooth from the inside rather than from the surface. Whitening suits adults wanting a brighter smile with healthy teeth and gums; it is not carried out during pregnancy or breastfeeding, and the dentist will explain the expected outcome and how to maintain it.
