I have used PreviDent in the past with great success. I was happy to find it at Dental Stores. Dental Stores shipped the items quickly and they were packed to keep them from damage during shipment.
Because my teeth and gums are showing signs of sensitivity, my dentist recommended that I switch to PreviDent sensitive toothpaste. I’ve only been using it for a few weeks with my electric toothbrush but I believe that I can already tell a difference. My teeth are feeling more comfortable when I brush around my most sensitive areas. I expect that the longer I use PreviDent the more my comfort will increase!
