Tis a reet bugger drawing cold air into your mouth and then experiencing, what can only be likened to, a red hot nail being prodded into your jaw.

Any, non – smartarse, tips on treating/preventing this? 🙁

Do you get it every winter or following a cold?
I had a similar thing a couple of years ago and teh dentist just asked if i had had a cold recently,yes i had and its something to do with the nerves in the nose?! Passed after a week or so.

I find Arm & Hammer "Sensitive" works really well. Sooo much better than Sensodyne.

Just started last weekend.
*goes to look for comedy toothpaste stuff* Thanks for the tip.

I had the same problem. Had to ride to work remembering to keep my mouth shut. Needed a filling. Dentist said I also brush my teeth 'too vigourously' and have worn them down!
