Can't open her mouth, I have a few observations and suggestions that I wish someone had given me a couple of weeks ago:
Safeway Signature soups (the kind that come in a refrigerator case and cost about $4 for 24 ounces) blend better than anything else that tastes good. Coconut Thai Chicken Bisque is incredible. My mother justly termed it a "beautiful soup".
If you've ever thought you only like food and drink really cold, or really hot, this situation will change your mind. When you can't sip and everything has to go past your teeth, tepid has its virtues. Oddly, Ensure is better fairly hot.
Ask for that wax they give people with braces. Buy Anbesol and Biotene. And those little plastic toothpicks with green rubber tips. And Benefiber. (It really does dissolve completely in liquid, and you may be sorry if you don't use it, because juices, it turns out, don't contain much fiber. Especially that stupid "Green Machine" which has the look of virtue and the fiber content of pudding.)
It's surprisingly easy to turn away from real food and just not think about it when you have no real choice. And I love, love, love real food. I will run back to its arms as soon as they let me. But now, I just turn a cold eye and keep moving.
I have not found anything that helps me talk better. I know someone has tips, I just don't.
You will be tempted to think and talk about this condition all the time because you are inevitably obsessed because it affects almost all you do. It would be wise for everyone's sake to resist the temptation as much as possible. I have failed. As you can see.
