Hey everyone, I'm having some issues with my tongue. It stays white quite often, and sometimes I wake up in the morning feeling like my mouth is incredibly dry. I manage to get rid of the white coating by brushing, but it just keeps coming back. A few days ago, I noticed a little swelling underneath my tongue on the left side, and I'm honestly not sure what it is. I've attached a photo so you can get a better look and let me know if you've dealt with anything similar.
https://prnt.sc/o3dkgf I'm getting pretty worried about this. My oral hygiene is solid—I brush every morning and night, and sometimes even during the day when I'm home. I'm 21 years old and I wouldn't call myself a heavy smoker; I usually go through one pack a week.
