In-Practice Whitening

Our in-practice whitening treatment delivers a visibly brighter smile in a single visit. The procedure is carried out by our trained clinicians using a controlled professional whitening system that achieves stronger, faster results than at-home products.

Before treatment begins we carefully assess your teeth and gums to confirm whitening is suitable for you. A protective barrier is applied to shield the gums while our advanced whitening gel lifts deep staining and lightens the overall shade of your teeth.

The process is fully supervised throughout, with steps in place to reduce sensitivity and protect the enamel. It is an excellent option for patients seeking a brighter smile ahead of a wedding, an event or a special occasion. We recommend booking at least a week in advance, as gums can appear slightly pink or irritated immediately after treatment before settling, so it's best not to leave this until the last moment.

In the UK, tooth whitening is the practice of dentistry and may only legally be carried out by professionals registered with the General Dental Council. All whitening at Only One Clinic is delivered under the supervision of our GDC-registered clinicians.

Whitening a single dark tooth

Sometimes one tooth darkens on its own, most often after root canal treatment, when the discolouration comes from within the tooth itself rather than from surface staining. Standard whitening alone can't always reach it.

For these cases we offer inside-outside whitening, a careful technique that lightens the tooth from within as well as from the surface, gradually bringing it back in line with its neighbours. It's a conservative approach that can restore an even, natural-looking smile without the need for a crown or veneer, and we'll advise honestly on whether it's suitable for your tooth at consultation.
