[This review was collected as part of a promotion.] This toothbrush is incredible and after only 1 week of using the 2 week whitening program which I have linked to my phone and toothbrush via Bluetooth and the Oral B app, I have honestly noticed the difference in the appearance of my teeth. I have always struggled with plaque build-up and a general discolouration of my teeth which I have obviously never been happy about. I have always brushed my teeth twice a day as recommended and used an electric toothbrush, but nothing has ever worked up until NOW! My teeth look whiter, feel smoother and cleaner, which makes me feel like I have left the dentist every time I brush. It also reminds me to floss!
