Enna,
So sorry to hear about the eating diffculty. Does that tooth need to come out to give you relief?
I just went through wisdom tooth removal with my son and had my own taken out just about 3 years ago. I found getting creative to power pack nutrition helpful. In addition to smoothies you might try Power Pancakes. You can make them with egg white, quick oatmeal and either cottage cheese or yogurt for either sweet or savory. Sometimes I grate in zucchini. Toppings like pureed black beans go nicely on the cottage cheese variety with avocado and sour cream. I know it doesnt sound great but they are actually pretty tasty and good for you. Cheesy risotto cakes are yummy and easy to eat too...
Hamburgers run through the blender do not sound appetizing.
