When you eat cookies or biscuits and at the same time drink water or coke, you may notice that the flour of the cookies is mixed with water to form a sticky substance like mud that sticks to your teeth, which makes you uncomfortable.
You can use a toothpick or a string of dental floss to get the the sticky flour off the teeth, but most people don't bother to do that. Instead, you may use your tongue to do that.
Is it correct to say "wriggle your tongue on your teeth to get the sticky flour off"?
