That's always easier said than done, isn't it? I'm sure many of us wish they had taken better care of their bodies when they were younger, but sometimes life gets in the way, long term impacts are unclear, and we overestimate our ability to "fix it later".
Reversing a condition once you have it is an order of magnitude more difficult to fix than to prevent, but if you're in luck and able to do so, every day now has the potential for taking a step in the right direction.
My favorite example of this is post-menopausal women regaining bone density, muscle mass, balance, mood etc. to rival women half their age in a matter of a few weeks (weight training). The same can be said for pre-diabetes, early T2, high blood pressure, addictions... the list goes on.
With regards to OP, I hope you find some relief somehow! I still have some baby teeth with very short roots; the second I get inflamed gums my pain level approaches levels were I can't function properly. What is the symptoms of receded gums?
Nowadays my gums just don't bleed ever, period, even when the hygienist is scrapping away calculus.
The potential of the stem cell space is incredible. Another interesting development is patients "cured" of HIV following stem cell transplants to treat leukaemia - which has no direct clinical implications given the significant risk of stem cell transplant but does inspire hope for the future [1].

I think too many HIV patients were too compromised by opportunistic infections to ever be healthy enough for stem cell transplants
