Hi again B.Bach
Lets see... yogurt, applesauce, oatmeal, instant breakfast, pastas (cut up), ground beef, and rice. Those last three can be served up in different combinations. Many vegetables like green beans, peas and carrots can be mushed up against the roof of your mouth with your tongue if they are well cooked. You've already covered eggs and potatoes. They can be made in a variety of ways that don't need chewing.
If foods get stuck in the extractions sites most should come out with a slightly vigorous rinse. If something should really
get stuck in a socket, most drug stores sell syringes (such as an ear syringe) that can be used to gently flush out the offending food.
