Extractions of teeth are done if the advantages of removing a tooth outweigh the advantages of keeping a tooth. Such situations arise when the teeth are grossly decayed beyond repair or if they are severely infected.
Extractions of teeth are also done for Orthodontic treatment when suggested by the orthodontist based on space availability and requirements for correcting different malocclusions. Extractions are also done when teeth erupt in awkward positions and can’t be set right.
