Pain, discomfort, and functional impairment after extraction of primary teeth in children with palatally displaced canines - a randomized control trial comparing extraction of the primary canine versus extraction of the primary canine and the primary first molar.

Tooth extraction was associated with low levels of pain and discomfort on a group level. Extraction of both the canine and the first molar was associated with significantly more pain and discomfort than was the extraction of the canine only. Extractions were associated with chewing problems among one-third to half of the children, otherwise, few children reported any jaw impairment after extraction.
