Interproximal Reduction (IPR) is the removal of small amounts of outer enamel between two teeth to correct crowding or reshape the way teeth meet. Removing a small amount of enamel does not damage teeth, and since IPR doesn’t go near the teeth’s nerves, the process doesn’t hurt. IPR can be done manually, with a flexible diamond-coated file strip; or mechanically, with a thin spinning file.
