It's totally normal, and you'll never be able to stop it. Pigs excrete excess calcium in their urine, and you can't, and shouldn't, lower the calcium in the diet until the spots go away. You'll wind up with a pig with broken teeth and bones if you do that.
Large and/or gritty spots are a sign that you need to address calcium in the diet. But some pigs will have excess urinary calcium no matter what you feed them. Others will never have it. I once pig-sat for a pig for six months that ate all sorts of high calcium foods all the time, and never had an issue. He lived to be eight years old with never a urinary problem. I also had two litter mates, one of which had repeated bladder stones and eventually died of complications of them, and her sister never had any difficulty.
So all you can do is keep calcium low, but not zero, in the diet, and cross your fingers that you don't have a stone-forming pig.
