Spinach contains oxalic acid, which is released when you chew it. (same feeling with rhubarb).
Calcium oxalate is not soluble -it deposits on your teeth, which results in the gritty, spinach-mouth feeling.
BTW: The sensation worsens if you drink milk while eating spinach, since this introduces even more calcium into the mix.
Note: If you're subject to calcium oxalate kidney stones (the most common kind), spinach is on the top of the list of foods to avoid!!!
