I was always hesitant to smile and show my teeth. After years of coffee for breakfast, diet coke with lunch and red wine at dinner, the pearly whites were not so white. I went to a place in Canary Wharf called Moda Donna Beauty Clinic and had laser whitening in an hour. It was so simple and the results were immediate. Now i smile all the time and just wish i had done this sooner!! (especially since i have a toddler and thus the camera comes out for photos a lot more these days)
