even just touching it will make it hurt.

your condition is known as post-restorative cold sensitivity. It is one of the issues that arise with restorations (fillings) such as amalgam and composite. There are two different types of sensitivity: cold and hot. You seem to be experience cold sensitivity. This is when the cold substance, whether its air or water, creates a slight pull on the nerve on that tooth; this very slight pull is whats causing your pain/sensitivity. This pulling action only arises when a portion of your tooth, the dentin, is exposed to the outside. This exposure is mainly due to the restoration as it is allowing the air/water to create this pull. You can try using sensitivity toothpaste, such as Sensodyne, to relieve the pain as some of these may help close the exposure area. I would also suggest seeing your dentist as he will supply you with personalized information based on your case. Good luck!
