Recommended by one of Britain's top dental specialists, Overnight White is the safe, fast and easy solution for teeth that are yellowing or stained. Invented by an Italian doctor, the pen dispenses a unique gel containing whitening properties. The active ingredient forms a light, transparent, impenetrable membrane which, as soon as it's in contact with saliva, breaks down and removes the molecules that are causing your teeth to yellow. To use the pen, simply rotate the top, brush the gel onto your teeth's surface, let it dry for a minute then leave for 3-4 hours – or overnight for best results. You can then brush your teeth as normal.
