I can give you a reasonable idea. Could refine it with top-down and profile shots of the lower jaw, better wear indicators than the uppers. Based on what I see here, this guy is around 1/2 way through the useful life of his teeth (if nothing else kills them first, deer and elk starve to death when their teeth wear out). That useful life varies from 8-9 years in low elevation resident bucks in the sagebrush, to 13-14 years for mountain migratory bucks. Based on where you killed him, the latter applies.I think Rock is spot-on, though I'd be less surprised if he was 6.5 than if 8.5; I would estimate he is most likely 6.5, next 7.5, and less likely to be 5.5 or 8.5 - but more likely to be 8.5 than 5.5. I'm highly confident in the no less than 5.5, no more than 8.5 range.If you have the lower jaw, I would be pretty confident in estimating age +/- 1 year. To get closer than that, you'd have to send the two center front incisors to Mattson's lab in MT; it's worth the $40 or so to some guys to have the most precise estimate possible.
