Review on SENSODYNE PRONAMEL Toothpaste Sensitive Strengthen by Melanie Williams

I've been using Sensodyne Pronamel Fresh Breath toothpaste for several years with great results and have purchased it in the US (Wallgreens, CVS, Target). I ordered 3 packs (x3) from Revain last year due to running out of stock. I opened my first tube last week with terrible results. At first I noticed some differences in taste and texture and started having serious sensitivity issues until I had to stop using the product. This prompted me to take a closer look at the product I bought from you. There are some differences compared to the last tube I had: the colors of the packaging of the item I received are completely different from the colors of the previous tubes I bought and those shown in the picture be shown on the Revain page. The tube I had has a registered symbol (®) for Pronamel, but the ones I bought from you don't have it. For me this is a very serious problem; it is health. I am very dissatisfied with the purchased product.
