How much shifting do teeth do after 65 - recently had #28 extracted #29 is also missing (#27 inplace #30 slightly slanted inward #31 still in place and all healthy). Am in good health otherwise.

Hi, thanks for using JustAnswer.com!
It's essentially impossible to predict whether your teeth are going shift as a result of the recent extraction of 28, since literally every single person is unique with regard to their tendency toward tooth shifting, once the "full, intact-arch equilibrium" has been disrupted by extractions
However, since you say that #29 has been missing for some time, it might be pretty safe to say that most of the shifting that #30 is going to do mesially, that is, toward the front, will have already occurred.
Now, what does tend to continue to happen, although quite slowly, is that the upper teeth that are now unopposed, meaning no lower teeth to bite against, will continue to grow downward to try to fill in that lower space. This is technically called "super-eruption" and would occur just the same if the upper teeth were the ones that were missing: the lowers would then tend to slowly "grow" upward to try to fill the space
Of course. without being able to see your entire clinical picture I cannot provide specific diagnoses for you, but you say that #30 is tilted slightly forward toward that now empty space. What happens when these molars are permitted to shift mesially like that is the back side of the biting surface moves up as the front side of the biting surface tilts down. This makes that back part of the biting surface of the tooth into what we technically call an "occlusal interference", meaning that part of the tooth tends to hit early in the bite. This is generally a v. bad thing, and can lead to a habit of clenching and grinding, technically called "bruxism". This can lead to TMJ problems, which can be quite nasty.
The same kind of thing can often happen as the upper, unopposed teeth begin to shift downward: parts of their biting surfaces come into the bite earlier than they're supposed to...
over the v. long term, if those unopposed teeth are allowed to super-erupt too much, they can literally come down and touch the lower gum, or ridge, where the lower tooth used to be when all the rest of the teeth come together in the bite. Then there is no longer any room to place any sort of tooth replacement, should you ever want to do that to restore some of the chewing function of that area
Have you ever considered getting some sort of replacement teeth for that now empty area on the lower right in back/
the only way to prevent any more of this slow but steady shifting of the teeth is to restore the equilibrium with in the arches of the teeth by placing some sort of replacement teeth into the spaces and restoring the chewing function
Is there any other information I can provide for you?

#30 is a crown as is tooth above. both are solid and the top tooth meets #30 at the front edge (that is - at the lip side of my mouth) solidly and a little less touching at the back side. am not considering a bridge which was the solution advise among several because of my age and reluctance to damage two healthy teeth to fix one space.
ok, I agree completely with the concept of leaving healthy teeth untouched when possible!
an excellent treatment option for replacing the missing 28 and 29 might be dental implants
