Last May I embarked on: 6 implanted sockets for 8 (or 9?) teeth, which included the four teeth immediately in the front of my upper mouth ("All I want for Christmas is my four front teeth..."), a sinus lift, and a bone graft where the bone between the sinus and the jaw had become literally paper thin. About three weeks ago I had the last of implant sockets implanted in the bone graft AND! A SPECIAL BONUS PRIZE!! a large polyp removed from my right maxillary sinus and yes, I CAN breath better now!

Wickedly expensive, and the polypectomy (if that's what it's called) was the only thing covered by insurance. But the fix should last for the rest of my life (my brother busted out my two front upper teeth back in 1959 by making me go ass over handlebars on my bicycle), I can play the trumpet better that I could even in high school*, I can eat a apple or corn on the cob without worrying about the partial plates I wore for years, and I don't know how to describe how good I look since there is nothing above the perfection I was.

A sinus lift doesn't show, but it does help you to breathe better. Ripping out a polyp the size of a pack of small post-it notes also helped, of course. The bone graft was needed because I could have eventually chewed something and broken through the bone of the jaw.
My blood oxygen level (I've been seen doctors a lot lately because the end-of-the-year rush for surgery and such is over) has gone from 92-94% to 97%.

Warning: this is a looooooong-term commitment. A bone graft will take about 5 or 6 months to "take" enough so that the implant sockets can be put in. The metal "posts" for the sockets for my latest (and last) sockets will be put in in June.

I will state it bluntly: if you can in any way afford it, do it. Especially the sinus lift and bone graft. I was lucky -- we had some "Required Minimum Distribution" coming in and this allowed us to claims some of the expensive as medical and use it as a deduction on our income tax instead as taxable income (this year will be different!).

Just two further thoughts. First, be sure that they use general anesthesia because the pain will be bad enough for the first few days afterwards, and secondly, please do get someone to drive you home from the surgery -- and hopefully stay with you for the next three days or so, holding your hand and bathing your fevered brow and making sure you don't do something REALLY dumb like try to walk down the stairs to the basement.
