A flap of gum has grown over the lower wisdom teeth on each side of my mouth, so I cannot chew. (My previous statement that my gums were swollen was incorrect.) After consulting with oral surgeons and my other doctors, we have decided there is no good solution under my circumstances, or at least no solution better than living with it.
So far, I have been relying heavily on thinned hot cereals, pureed bean soups, banana ice cream shakes, yogurt and fruit smoothies, and a commercial nutritional drink with a lot of calories, protein, and fat. Though I'm generally in favor of real food, the commercial drink is very convenient and very chocolatey.
I have been feeling sorry for myself about needing to get all my nutrition in liquid form from now on. I miss eating solid food a lot.
Then I saw that people with broken jaws face the same problem. This gave me hope that I could find a tasty variety of nutritional drink/smoothie/shake recipes.
Some of what I found sounded terrible. For example: pizza, hamburgers, Chinese food, or Mexican food, plus some extra liquid, put in a blender and then strained. Also, baby food. I have been having problems with nausea and vomiting, and I get queasy just thinking about these. But if I get desperately bored with what I'm doing, I might have to give them a try.
I did learn about some promising additions like nut butters, hemp and flax seeds, and tofu. Those are probably where I'm going next to boost the nutrition of what I'm doing. Vegetable juice, too.
If you have some clever ideas for drinkable, nutritious, and tasty foods, please pass them along.
