I will preface this review with the fact that Desy at the Citidel Mall in Colorado Springs was customer friendly and did a nice job, and yes, my teeth did come out whiter...HOWEVER, my gums and mouth paid the price!!! My gums were ""burned"" and are now very raw around the teeth in the front of my mouth, so bad they continue to hurt and bleed every time I try to brush my teeth, who knows how long this will take to heal?
