Short Answer: Probably.
A good general rule in life is if something seems too good to be true it probably is. We get asked everyday about information that is all over Facebook and other media. It is very dangerous to take these at face value, when often they are posted by someone trying to make money. Recently a friend asked about a brand of toothpaste being marketed on Facebook, it was promoted as a new remineralizing agent that would rebuild (heal) the enamel on teeth. They quoted a prominent dental researcher from Japan, who’s research is in remineralization of teeth. He asked me to find out if this toothpaste was legitimate. I went to the companies website, found that they claimed the majority of the research was done by this dentist in her private lab, and a research facility at a university in the UK. I went to the University’s research website and could find no research published on this toothpaste or even this topic in general. I then went to the Research Dentist in Japan’s website. At the top of her website was a Disclaimer, “We are not associated with [toothpaste brand], we do work on products that remineralize teeth, but they are in trial stages and the products we use, if put in the form of a toothpaste, would melt the tissue of your face.”
Our recommendation is that when you see these things, if you feel they might be realistic or beneficial to you, please discuss it with your dentist. Often the home remedies and “Amazing” products online, do not help and are potentially harmful to your teeth and overall health. Your dentist should know about new and upcoming treatments and products. It takes years for some of these new things to pass through health Canada, so by the time they are available everyone knows very quickly because dentists have been waiting for the Health Canada approval to start using it.
In short, Yes those things are probably too good to be true, so please ask a professional.
