Reddit is mostly back up to full capacity Monday after a weekend revolt in which moderators locked major portions of the site off from the general public -- all because of the dismissal of Reddit's director of talent, Victoria Taylor. There's little doubt that Taylor was a beloved figure in the Reddit community.
I agree with ChitChatNine...I just had thyroid surgery, my doc told me to watch out for numbness and tingling in the face, lips, hands, and if I had that to go back to the doc.
Any inflammation of this nerve leads to the symptoms you said. Tongue numbness and face numbness is due to labial / lingual / facial branches of the nerve { as you see only half of the tongue is numb }. The cause of inflammation needs to be found out. It is mostly the tooth infection which is the culprit. You may not feel pain in the tooth that severe earlier.
