Then cream of wheat, broth, and mashed potatoes shall you eat. Did your surgeon say if you’ll be able to use sauces and spices? If so, a little tiny bit of olive oil followed by some garlic powder and maybe a drizzle of BBQ sauce in the mashed potatoes makes them to down a lot easier (gravy likewise if that’s allowed). Heavy whipping cream in vegetable or chicken broth along with some miscellaneous spices like Italian seasoning, garlic and onion powder, pepper, etc. will surely make it less healthy but could make it a bit tastier. Cream of wheat can have some pumpkin spice in it and maybe a drizzle of maple syrup (the real stuff).

That being said, do absolutely none of what I’ve just said unless your oral surgeon advises you that you can. I would check any notes the surgeon might’ve given you and call their office to see if maybe this is something the receptionist would know. If not and you’re not able to communicate with the surgeon directly, then be conservative: this is your health. If anything, you can rationalize it as a way to get even more out of food once your new implants are here!

Like other commenters have suggested too, if you call their offices, I would ask about meal replacement shakes. The plant-based ones I drink on occasion have 32g of protein, and they have a good flavor and texture and make me feel full for a pretty long while.

Well, then there’s your answer. Go ahead and ignore it. It’s your mouth. Show that oral surgeon they aren’t the boss of you!
