Is the numbness in your tongue gone yet?
Maybe it's because I haven't had enough Vitamin C, but my tongue has been rough lately.
No, thank you. I burned my tongue last night, so I don’t want to drink any coffee.
The kanji and the word are exactly the same. That means they share meanings as well.
Uses the same reading that you learned with the kanji. Go ahead and use your tongue and say the reading out loud... "した."
