Abstract, a good dentist, good home cleaning and a mouthguard make a really big difference, even when there's already a lot of damage. Teeth and gums actually repair themselves to some extent if we give them the right conditions.
When I had the initial assessment with my current, good dentist, he was expecting to have to do some surgery on my gums and possibly replace some inlays and crowns. He waited because he never rushes in, always waits to see if work can be avoided or at least delayed, in the best interests of the patient. We've been waiting for almost four years now, and still no need.
There's a really good dental hygienist at the practice who I see every three months. She taught me how to clean my teeth properly, including things for the damage that's already done (like brushing with water only, not toothpaste) and everything has completely stabilised.
Do you actually have a splint? Apparently in 99% of cases they stop any further damage. They're really expensive but I do think they're worth it. Dental work is expensive too, and that may be unnecessary if you have a splint. In my case, it has been.
