Stripping (interproximal reduction, IPR) is a procedure in which a small amount of enamel is carefully removed from the sides of a tooth (where two teeth touch) using an abrasive material. These areas of the teeth (the side contacts) are normally out of reach of the triggers that cause painful sensitivity – the acids in fruit and juices, cold food and drinks, and cold air breathed in. Teeth may become more sensitive for two or three weeks after IPR, but this isn't typical and more often than not it doesn't happen, because these triggers don't get in between the teeth anywhere near as much as they affect the front surfaces.
This answer is for general information. Your own case needs an examination by an orthodontist.
