Peter Attia prefers a children's soft toothbrush over a mechanical toothbrush for brushing his tongue.

“although i have to be honest with you i've never been able to brush my teeth sorry brush my tongue with the mechanical toothbrush because i the no yeah i have to use the okay all right i got it you have find a i usually like i like a children toothbrush yeah so you want a soft duracell toothbrush right soft soft for the tongue yeah just get a separate one”

“i used to scrape my tongue i have one of those tongue scrapers i used to do that and then my wife got so mad at me because she said that's so disgusting it makes me sick get rid of that stupid tongue scraping piece of expletive so i still have it don't tell her but i don't use it anymore”
