do you have a blender to use after the chopping ? adding some stock or yogurt to thin it ?
the issue after dental surgery is to be very careful to not disturb the ' clot ' on the surgery side.
you can disturb it w blended food , but it helps not to chew first .
so think about keeping the food on the other side of the mouth from the surgery
small amounts might be a good place o start.
and don't use a straw . using a straw created negative pressure in the mouth and can disturb
a clot.
good luck.
