I am very interested in this too. I had horrible reseeding/bleeding gums and perhaps I am tripping but I believe they are improving dramatically already after 6 weeks of re-feeding/re-introducing gluten. I was shocked to see in the mirror just before that they almost look normal and the gingivitis type symptoms are nearly gone. I’ll keep you updated as to how progress goes, but I believe this is working.
I have been brushing every couple of days with a 1:1 mix of coconut oil and bicarb soda. And sometimes rince my mouth out at night with water/bicarb.
