Teeth Whitening (In-Office)

Professional teeth whitening lightens the natural shade of the teeth using a controlled peroxide gel. DEN-MED offers in-office lamp-activated whitening for a faster result in a single visit, a laser whitening option for both arches, and custom take-home trays for gradual whitening at home. A single darkened root-treated tooth can also be whitened internally. A clean and check-up beforehand gives the most even result.

Professional whitening uses a dental-grade peroxide gel to break down the staining within tooth enamel and lighten the overall shade, achieving results that over-the-counter products generally cannot. At DEN-MED the in-office method applies the gel under supervision and activates it with a lamp, lifting the shade noticeably in a single appointment, while a laser-activated option is offered for treating both arches. For those who prefer to whiten gradually, the clinic makes custom-fitted trays so the gel can be worn at home over a couple of weeks; an in-office result can also be topped up later with a lower-cost refresh session. Before whitening, the dentist checks that the teeth and gums are healthy and usually recommends a professional clean so the gel acts evenly — existing fillings, crowns and veneers do not change colour, which is taken into account when planning. Temporary sensitivity to cold is the most common after-effect and typically settles within a day or two. A separate internal whitening technique is available for a single tooth that has darkened after root canal treatment, applied from inside the tooth over one or more visits. Whitening is suited to adults wanting to refresh discoloured but healthy teeth; it is not carried out during pregnancy or breastfeeding, and results depend on the starting shade and on limiting staining foods, drinks and smoking afterwards. The dentist confirms suitability and the best method at consultation.
