Tongue Yellow at Back

Sexual health

Hi,

I’ve discovered yellow goo at the back of my tongue is this normal or anything I should be concerned of?

its just built up debris of food etc use a tongue scraper

if i didn’t use a tongue scraper could it cause an infection over long term? I’ve never thought my tongue would require attention.
