A brighter smile is something you want to enjoy beyond the journey home. It is natural to wonder whether you will still notice the difference in next month's photographs or over coffee with a friend. The useful answer starts with realistic expectations, rather than a promise that every smile will stay the same.
Does teeth whitening last forever?
The NHS and Oral Health Foundation describe results from dental whitening that can last several years but vary. Those observations concern the treatments discussed by those sources. They do not establish how long the product used at an ishSmile visit will last; we do not advertise a duration guarantee.
Ask your dentist what is realistic for your teeth and the treatment being discussed. Your own starting shade, the change you hope for and the advice you receive are more useful than a headline number taken from another person's experience.
Which habits can affect a whitening result?
The Oral Health Foundation explains that smoking and drinks such as tea, coffee and red wine can bring staining back more quickly. It also highlights brushing and regular dental cleaning as part of maintaining a result.
That does not mean turning every meal into a test of whether you are protecting your smile. Ask for practical advice that fits your routine, and keep any instructions from your provider somewhere you can find them after the appointment.
When should I consider another whitening appointment?
There is no repeat-booking schedule advertised here for every customer. If you notice a change, discuss it with your dentist before deciding what to do next. Ask whether further whitening is appropriate and how it would fit with your dental care.
Check whether a proposed follow-up is a separate appointment, what it includes and what it costs. A discount on an initial visit does not tell you the arrangements for later care, so make those questions part of your comparison.
Make your London booking with clear expectations
The ishSmile offer is £125, usually £175, at Brick Lane or Belsize Road. The listed appointment includes product-use guidance and starting and final shade comparisons. You apply the product yourself. Ask the team about booking details; personalised dental advice must be sought separately.
Read the aftercare and staining guides alongside this article. Together they can help you prepare questions about everyday care, the result you hope to see and whom to contact if you would like advice afterwards.
