But there are a few who did for other people, without a thought for their own vanity or self-improvement. They transform their teeth from dull beige to a sparkling white in order to help others in tricky situations. However, what could these situations possibly be?

Lighting the Way
If you really go to town on transforming your teeth, you could end up with a smile so brilliant that it could guide ships back through rocky seas, or lead a party of lost hikers back down a mountainside in the pitch darkness. Not often is someone able to save lives simply by smiling but in these instances, it could easily happen.

Picture the scenario: a group of valiant local walkers has gone on their annual trip. It starts of fine but then bad weather unexpectedly sets in and they become lost and disorientated. They begin to panic, supplies are running low and everyone has finished off their last drops of water. With night fast approaching, it looks as though all might be lost and they'll have to sleep on the mountainside and just hope they make it through to the following day. Then, one of them spots a small, glowing light somewhere in the distance.

The light seems to be getting closer and as it does, it gets much brighter and the walkers can see each other once more. They wonder what can be creating such a powerful glow and then they spot the outline of a man. As he gets close, they can see his is grinning from ear to ear and the light seems to be coming from his mouth. Incredible as it seems, the man is picking his way up the mountainside with the glow of his teeth. He leads the party of hikers back down to safety and they thank him as they sip cocoa.

The benefits of white teeth
This is just one of the fantastic extra benefits of tooth whitening. Just think of all the good you could do, not just for your image, but also for other people. A set of pearly white teeth could turn you into a local hero and you could use your incredible new-look teeth for all kinds of little jobs around the community. How about lighting the way back from the bingo hall so elderly ladies don't slip on the pavement and sprain an ankle?

Alternatively, perhaps you could save the church hall some money but using your teeth to provide light for the annual Christmas party. There really is no end to all the good things you can do with your new teeth: it just comes down to imagination. Nothing quite beats the warm glow of helping others and all this could be yours for the price of a tooth whitening kit.
