The truth about over the counter whitening. This interesting BBC  programme which was televised last night followed the trials of several over the counter whitening treatments and found that all of the results were not detectable by the human eye. You may think your getting a bargain but realistically you would be better off investing in a professional whitening service that only your dentist can provide!
