Can u just chew on one side??

Have you considered a baby food grinder....sort of like making your own hamburger.

cheese like mozzarella, monterery jack, these are soft cheeses
hamburger
liver
tuna salad
eggs as eggs salad, cheese omlet, fried eggs
sardines
well cooked stew meats that fall apart

good luck with the crown

i changed to brushing with baking soda which is more gentle than commo toothpastes and gums are the better for it.
