Simple Extraction: form a vital part of general dentistry as there are various reasons for which extraction and subsequent tooth replacement is the only viable option. The various conditions which mandate an immediate extraction are vertical tooth fracture, grossly decayed tooth, highly disfigured or discolored tooth structure. Also in infected deciduous or milk teeth in children where the in grossly decayed teeth there is a high chance of the infection spreading to the underlying permanent tooth bud. This can cause permanent or irreversible damage to the developing permanent tooth.

There are certain cases in which intentional extractions are necessary like for creating space in orthodontic cases. This is important in patients with excessive crowding and lack of space due to a small arch. Also in cosmetic cases of smile designing and makeover sometimes extractions are necessary for creating space and aligning the teeth for a perfect smile.
