@SpaceManJim I'm not sure about receding gums but anytime i have gum inflammation tocovit clears it up rapidly, not sure of the mechanistic functions of how this works. Sometimes I think my gums aren't necessarily receding but the teeth are protruding; I think widening the upper and lower palettes could provide more room for the teeth to fit comfortably in their proper place. I think good oral hygiene, a healthy microbiome, and good nutrition are you're best bet. It could be gum disease which could be explained by a weak microbiome, maybe methylene blue could be an effective short term way to reduce any bacteria causing minor gum disease. I also have had this problem but my microbiome is now healthier than it has ever been I believe and my gums are no longer receding; and it all started when i started taking methylene blue and then stopped taking it and focused on clearing out SIBO, and eating healthy. If i have any suspected microbiome issues I usually go to herbs rather than antibiotics. Ginger, garlic, oregano, etc are all good but i'm not sure how much oregano oil effects the microbiome to be honest it might be overkill unless you need a reset.

in my experience my pen0r feels incredible with red light and IR, i wouldn't be surprised it it promotes growth, that's certainly what it feels like.
