Stripping (interproximal reduction, IPR) is a procedure in which a small amount of enamel is carefully filed away from the sides of the teeth to create space for aligning them. It is most often used on teeth that are wider or triangular in shape, particularly the lower front incisors. The amount of enamel removed is minimal and does not affect the strength of the tooth.
IPR can be used in two main situations – when the lack of space for aligning the teeth is slight, or when the shape of the teeth needs to be corrected to reduce the gaps between them.
This answer is for general information. Your own case needs an examination by an orthodontist.
