Tooth extraction can be defined as the removal of a tooth from its socket in the bone.
Your dentist always aims to save your tooth; however there could be circumstances wherein your tooth has to be extracted.
In the early days of human history many of the illnesses were attributed to tooth infections. Since there was no antibiotics in those days tooth extraction was performed for curing the illness.
Different tools were being used for extracting tooth at various points of time. The first one was invented by Guy de Chauliac in the fourteenth century and this was known as the dental pelican. This was the main tool that was being used until 18th century wherein dental key replaced dental pelican as an extraction tool. Dental key is replaced by modern forceps in 20th century and this is the main tool used at present for tooth extraction. Dental extractions vary widely and to facilitate different types of extractions a wide variety of instruments are being used.
