The "Piano" effect : This discoloration from the bleaching agent is a common problem. The strip whitens only the surface leaving the space between the teeth dark. Ask your dentist for professional teeth whitening without laser, followed by home whitening system with custom trays for the long term effect. You will be very happy with the results.
