You can whiten your teeth through professional treatments or at-home methods. Professional whitening is done by a dentist using stronger whitening agents, while at-home options include whitening toothpaste, strips, or trays. Each method can brighten your smile but varies in strength and results. Professional whitening done by a dentist usually leads to better results as the strength of the whitening legally allowed with non dentist / at home treatments is much lower.

You can get professional teeth whitening in London at any of our Ruh Dental clinics. We offer safe, effective whitening treatments at our Harrods, Fleet Street, and Notting Hill Gate locations, providing both in-clinic and dentist-supervised at-home options. Whether you’re looking for quick in-chair whitening or a customised whitening kit, our London clinics offer predictable results under expert care.

Teeth whitening works by using bleaching agents like hydrogen peroxide or carbamide peroxide to break down stains on your teeth. These chemicals penetrate the enamel to lighten the colour of the tooth, leaving you with a brighter and whiter smile.

Professional teeth whitening can last between 6 months to 2 years, depending on your habits. Certain habits like smoking or consumption of stain-causing foods and drinks (like coffee or red wine), can make results fade faster. Regular maintenance, such as top-ups, helps extend the results for a longer period of time.

Professional whitening treatments usually take about 1-2 hours in the dentist’s chair. For at-home whitening kits, it can take several days or weeks, depending on the strength of the product and how often you use it, you can also stop using it once you are happy with the results.

Natural methods include brushing with baking soda and oil pulling. However, these methods are far less effective than professional treatments and should be used with caution. We always advise consulting a professional at one of our London clinics when considering tooth whitening.
