I've only used Mentadent toothpaste for over 30+ years, and have not had any cavities since I've started using it! I, along with many others I've confirmed both personally and online, are very disappointed to learn that it has been discontinued! We would love to see this great product brought back, as the demand from loyal customers is indeed significant! The look and cost may be different than the majority of toothpastes out there, but, I have come to appreciate the uniqueness of the product design, and the cost is actually not really that different from other products on the shelf when you compare it realistically based on the amount of product received. This toothpaste has by far been the best I've ever used, and, I've always told anyone who asked that I completely believe that I've been cavity-free strictly due to solely using Mentadent! Though it is just a toothpaste to most, those of us who've been loyal to our Mentadent know it is the reason for great oral health! We don't want to all start walking around with less than desirable oral health and superb smiles; We simply Must have our Marvelous Mentadent back!
