In one of the support groups, i read h pylori can colonise in oral cavity.. i have some roughness in my buccal mucosa, last year there was hyperpigmentation and it was in both the sides, can this be due to h pylori? All my stomach issues started post this. I was told to use a toothpaste with biocin so that is disrupts the biofilm coating of the bacteria.. i have attached a pic of my mucosa, you can see the residual pigmentation (its very less though).. After 1 round of antibiotics, H pylori was still positive, so this time i want to take additional precautions... please suggest me any biocin toothpaste/mouthwash to aid the h pylori eradication! Thank you
