I have been using Dr Hisham's mouth-rinse and Dental Powder for over 2 years now.
Recently I had run out of the Dental Powder for 3 days. Having had to go back to normal toothpaste was a shocking reminder as to why I don't use it anymore. It not only tastes unnatural, but it doesn’t leave me feeling like I have a fresh, clean, neutral balance in my mouth. I'll be keeping the powder backed up in the cupboards from now on so I don't run out again!
