Many people are familiar with the techniques used to whiten teeth from the outside, but I doubt many of you know that discoloured teeth can also be bleached from the inside, out!

There are times when the teeth are discoloured from within rather than from run of the mill red wine and coffee stains on the outside. It usually involves one or two front teeth (upper or lower) that have been root-filled in the past and have become severely discoloured (brown, yellow or orange).

When these badly discoloured teeth are combined with a generalised yellow appearance of the other teeth (from years of staining) this makes for the hand-over-mouth, or lip over teeth, smile that so many patients seem to put up with.

Standard dental bleaching involves either using trays at home or a special light source used in the dental chair (see my teeth whitening blog for views on which works best). However it is also possible to bleach the inside of these very dark (root-filled) teeth, and at Winning Smiles we use a technique that combines both bleaching the outside of all the teeth and bleaching the inside of those extra-orange ones. The results are quite spectacular and often avoids the need for drilling and crowning these individual problem-teeth.

In the photo, two of these front teeth were ‘off-the-scale’ orange, the rest were just a creamy shade of yellow from normal staining. The patient had 10 days to go before his dream wedding in the caribbean. This is how he looked after a week of Inside-Out-Bleaching. Can you tell which ones used to be orange?

If you look really closely, two of the teeth are whiter than the others – yep, you guessed it, those are the ones that were orange a week ago!
