Tooth sweater 

When you go for a day or so without brushing your teeth, and the texture in your mouth feels like your teeth are wearing fuzzy little sweaters.

"Does anyone have gum? I forgot to brush my teeth this morning, and it feels disgusting."
"Oh, you've got tooth sweaters?"

The warm coat left on your teeth after giving a blowjob.

"After taking my man juice's moneyshot last night I woke up this such a tooth sweater."
