Does whitening really work? The proof!
There’s a lot of misleading nonsense in advertising and social media about tooth whitening, and a resulting confusion in the general public about what works and what doesn’t. The simple answer, like with most things in dentistry, is that if it’s done properly by a dentist who knows what they’re doing the results can be amazing and most people should do it.
Annoyingly, if you look even a little closely at many of the photos used to advertise whitening, you can see they’ve been Photoshopped (look out for telltale signs like much lighter gums and lips in the “after” photos or, in some cases, just a completely different set of teeth). So I’m posting these to show what really happens after a proper course of home whitening, using well designed whitening trays, the right product, and an appropriate regime.
The photo with the grey card is calibrated to make sure the camera hasn’t altered the brightness of the photo, and the shade tabs are the same tabs used before and after (these photos are taken with a cross-polarisation filter that removes reflections and allows you to see the real internal colours of the teeth).
