Ultradent's whitening products are sold only to licensed dental professionals. Patients may order a limited number of products including toothpaste at our Amazon.com Patient Store. Ultradent cannot guarantee the authenticity or efficacy of tooth whitening/bleaching products sold by an unauthorized retailer such as eBay, Smilox, DentaMart, or similar online stores. We have made efforts to discontinue selling to any dentist if we can confirm that they are the owner of an online store that sells Opalescence bleaching products. If you would like to report a Website for unauthorized sales of Ultradent's products, please complete our feedback form and select "Ultradent Overall."
