Just a moan really. Totally self-inflicted wound. I splurged on the enlighten teeth whitening programme and tonight was my second night on the stronger gel. I wore it for two hours, then woke up at midnight to take out the trays. Then woke again at 1:00 with unbearable pain in teeth, from sensitivity. I've taken paracetamol, sensodyne, the little densitising swabs, and it doesn't touch the sides. This is absolute crap.
