In-Office Teeth Whitening

Professional chairside whitening that lightens the natural shade of the teeth using a controlled, higher-strength gel applied by the dental team in a single session. In-office whitening produces a faster, more uniform result than over-the-counter products and is carried out after the teeth are assessed and cleaned. At SmileOn a take-home tray system is offered at the same price, and a special internal technique can lighten a single discoloured root-treated tooth.

Professional teeth whitening lightens the colour of natural teeth by using a peroxide-based gel that breaks down stains within the enamel and dentine. In-office (chairside) whitening uses a higher concentration than home kits and is applied by the dental team under controlled conditions, which gives a quicker and more even result in a single visit. At SmileOn Dental Studio the teeth are first examined to confirm they are healthy and, ideally, professionally cleaned beforehand so the gel works evenly; the gums and lips are protected before the whitening gel is applied and activated. A session typically lightens the teeth by several shades, though the exact outcome depends on the starting colour and the nature of the staining — whitening works on natural tooth structure and does not change the colour of existing fillings, crowns or veneers, which may need replacing to match afterwards. Some temporary sensitivity to cold is common for a day or two and usually settles. As an alternative or complement, the clinic provides custom take-home trays with whitening gel for gradual lightening at home, priced the same as the in-office treatment. For a single tooth that has darkened after root canal treatment, an internal (non-vital) whitening technique can be used to lighten it from the inside at a lower cost. Whitening suits adults with healthy teeth and gums who want a brighter smile; the dentist checks for decay, exposed roots and the cause of any discolouration first, and advises on realistic results and how to maintain them.
