Heres mine.
It's not intended to scare, but be thankful that you wont be as deep as I was. You shouldn't encounter this for getting dentures.
I had maxifacial surgery, due to my lower jaw protruding out, and mis-aligning my bite.
SO, they had to move the Upper Plate and the lower Jaw.
You go in, they prep you for surgery, and then wheel you in to the operating room. The last thing you see are the big round lights, and the nurse saying "BYE BYE". POOF - your out cold.
I awoke during my surgery, and they very quickly put me back out - I didnt experience any pain during that time, just heard the cutting going on.
They cut the area right under your nose on your skull straight back, and then cut the lower jaw bone and reset that to match the top. By cutting the top, they mess with your nasal cavities, and fluids may - may go down in your lungs.
With Plates, screws, lots of wire, and surgical stitches, I was sewen up and sent out.
A few hours later, I woke up with my upper and lower jaw Wired together so that I could not move. I could not open my mouth.
I felt like I had 500lbs of weight on my chest.
I was turning blue. My sister screamed, and I put both hands in an x on my chest and grabbed for my throat. Then I exhaled and the room was in shock.
I had about a cup of blood exhale from my nose and my mouth.
The nurses quickly rushed me to the Male Intensive care unit.
On the way there, the nurses threw a BIG bundle of blankets on my crotch, as I got a hardon from all the bumping and the meds (LOL).
I pass out, and then come to again once I hit the table in the male ICU.
Worst case scenario - they have to cut the wires on my jaw to get the breathing tube down my windpipe, or Puncture my side to get into my lungs...OR....the tube down the nose.
So they tell me "Ok you have to swallow when we put this in ok??"
I nod, "Here we go".
Keep in mind that the nasal cavity is still pretty raw from surgery. All I did was swallowed as much as I could.
By far..that was the most painful thing I have ever done.
I grabbed the bed, and ripped the mattress.
They started pumping my lungs out - through my nose.
600CCs later, they emptied my lungs of blood, after 2 trips down with the tube.
I apparently had clotted after that, as I didnt have many more issues.
I could finally breathe.
My healing process was slow, and eating was a bitch because everything went through a straw.
Luckily your surgery for dentures wont be that severe, as I was wired shut for 6 weeks.
Expect some pain, some swelling, but you'll be able to breathe, and eat soft foods I would imagine.
