Of course 20 years down the road all those side-effects will start to surface--maybe sooner! Cavities are a part of life--things in our bodies start to die off--some sooner then others--some are genetic, some from not proper care and some just happen! It would be a wonderful thing to find a way to totally prevent dental problems but I doubt this is it!
Seems may are looking for the easy way of course but as of now the only way I am sure of having the least amount of dental problems is work on your part to keep your mouth clean and also keeping up with your regular dental appointments and cleanings! That's life in the real world!
I would love this to be the real deal---who wouldn't?
