My co worker has straight gum rot, like a few millimeter layer where the gums meet their teeth that’s all whiteish green and they have horrendous breath I can smell 15 feet down wind of the AC system. This is due to their horrible personal hygiene, he has a wife with good teeth, I don’t know how she kisses him, I would vomit.
He’s only in his early 30’s and also just had to get one of his K9 teeth pulled out.
Just gotta get a reputable brand. I recently got a Popur X5 and it’s been real nice.
