I know this guy who spends probably 30-40 minutes cleaning his teeth before bed. He flosses with multiple things (regular string floss, floss picks, threaders - for people who have braces/permanent retainers, I think they’re called interdental brushes, and then he water flosses). After he is finally done flossing he brushes with an electric toothbrush. Then he will brush with a regular toothbrush, and use a baby/kid toothbrush in the “hard to reach areas.” He will wait 30 minutes or right before he finally goes to sleep and then use fluoride mouthwash. It’s great he wants nice and healthy gums and teeth but it’s just a little weird how many products he uses. He also obsessively stares at his teeth and gums examining them. I think he even has plaque disclosing tablets. It’s just odd. Is this normal?
