It sounds like your implant is for a single unit, rather than as part of a longer span, or for retention of appliance. Perhaps it is 31, as 32 is the right, lower wisdom tooth. I'd speculate you are replacing the second molar, not the third.
There are multiple variables at play. Some of these include: upper vs lower (bone densities come into play), whether augmentation of the ridge is required, patient medical history, etc.
Often an OMFS or periodontist will place them, then the prosthodontist will restore. Some GP's are skilled at both the placement and the restoration.
I had to wait three months until the bone came back strong enough, which apparently it has.
Probably 30 or 31. An hour to place an implant is reasonable if there is no need to do bone or soft tissue grafting.
No bone or soft tissue graft needed, fortunately.
It looks like the only pain I'll experience is when I get the bill.
