In-Office Teeth Whitening

Professional in-office whitening lightens the natural teeth using a dental-grade gel applied under supervision, covering both the upper and lower arches. It is used to brighten teeth that have darkened with age, diet or staining. KM Dental Experts recommends a hygiene clean beforehand so the result is even, and the dentist checks that the teeth and gums are healthy before treatment. Results vary with the starting shade and habits such as coffee, tea and smoking.

In-office tooth whitening uses a concentrated, dental-grade bleaching gel applied to the teeth under the supervision of the dental team to lighten the natural enamel and dentine. It targets general yellowing and staining from age, food and drink rather than the colour of fillings, crowns or veneers, which do not change with whitening. At KM Dental Experts the price covers both arches in a single in-clinic course. Before whitening, the centre recommends a professional clean — scaling and polishing — so that surface deposits are removed and the gel can act evenly on the enamel; this is listed separately within the hygiene menu. The dentist first checks for untreated decay, exposed roots or gum problems, as whitening is only carried out on healthy teeth and gums. During treatment the gums are protected and the gel is applied to the teeth; some people notice short-lived sensitivity afterwards, which typically settles within a day or two. Results depend on the starting shade and on lifestyle factors: coffee, tea, red wine and smoking all encourage staining to return over time, and a touch-up may be wanted later. Whitening is a cosmetic procedure for adults and is generally avoided during pregnancy and breastfeeding. The dentist will explain realistic expectations, aftercare and how to maintain the result, and will advise whether any existing restorations might need replacing to match a brighter shade.
