How do you keep holes clear of food?

For context the doctor did NOT give me a syringe. I’m 6 days post op (extraction on 12/20) I had all 4 removed and the surgeon placed dissolvable stitches. I mainly have been eating mashed potatoes, baby food, soups, and cut up pasta that I swallow whole. I’m kinda scared to chew lol.

Today one of my stitches came out but when I look there is still a small hole. I’m worried that when I eat, food will get stuck in there.

Any advice would be great! Thanks! :)
