Extractions or exodontia is the removal of teeth when these cannot be restored due to tooth decay, infections, dental trauma or gum disease. Before the procedure, the dentist will apply local anesthesia to numb the area where the tooth will be removed. Once the tooth has been pulled, a gauze pad is put into the socket and the dentist will have you bite down on it to help stop the bleeding; sometimes stiches are needed to close the gum edges as well.
Overall, having an extraction is generally safe but the procedure is prone to get bacteria and putting gum tissue at risk of infection. Your doctor might prescribe antibiotics and painkillers to lessen any disconformity. It is recommended to avoid rinsing or spitting forcefully for 24 hours after the extraction to avoid removing the clot that forms in the socket, eat soft foods during the recovery time, apply an ice bag to keep down swelling and continue brushing and flossing to prevent any infection.
