Just found 25% off safe and white teeth whitening products. I use their toothpaste and it actually has whitened my teeth and its also really good for bad breath! I think its also available online but you have to pay for postage if the value is less than £45.
Safe and White Toothpaste contains the unique Ardox-X technology for natural white teeth which helps to eliminate the harmful bacteria that cause gum inflammation and bad breath.
Safe and White® Toothpaste also affects the breeding ground of harmful bacteria, which makes the result long lasting. Gums are kept in optimum condition and gum problems are relieved. This ensures optimal oral hygiene and healthy white teeth.
