Primrose it needn’t be a long process. If you are clinically suitable, it can done all in one (long) day. That’s how mine was done. I had a pre-procedure appointment for examination, scans, measurements etc. Then on the actual day I had a 10am appt. The usual quick check up then he got to work removing the dodgy tooth. It was out before I realised!
Then he got to work installing the metal post. It’s quite a complicated procedure (to my amateur eyes, anyway) but eventually that bit was done. I went off for a rest in the waiting room while the machine they have produced the new tooth - I guess it’s like a 3D printer, really.
The tooth was then installed onto the post and there were checks to make sure it was oriented properly and was the correct size. Mine needed a little adjustment to match my bite as with a crown. That was the end of it, then, after being given instructions for oral hygiene, how to look after my mouth, pain relief and what foods are suitable while it’s healing. I think it was about five or six hours, all told, which included some hanging around time.
I did feel a bit knocked about for a day or two but regular painkillers helped and after 48 hrs I was back to normal. I had an issue later on when the cap come off but it was easily replaced and I think if it ever happened again, I could replace it myself.
