There are two methods of removing wisdom teeth. They can be by simple extraction or they are removed by simple minor surgical procedures. These are determined by their degree of impaction. Removing wisdom teeth either by extraction or surgery can be performed under local anaesthesia or under general anaesthesia.
Local anaesthesia means that they can be done in the clinic when you are fully awake or sedated.
General anaesthesia will mean removing them while you are asleep and is usually done in a hospital environment under Day Surgery. i.e, you go home about four hours after the procedure is performed. These can be carried out either in the private hospitals or restructured hospitals. The surgeons can be private practitioners or from government service.
The healing process begins immediately after surgery as your body sends blood to nourish the tooth socket. Simple pressure from a piece of gause is usually all that is needed to control the bleeding and to help a blood clot to form in the socket, which promotes healing. Within a day or two, soft tissue begins to fill in the socket, aided by the blood clot. Eventually, the bone surrounding the socket begins to grow, eventually filling in the socket completely, as illustrated here:
(note that there is a possibility of a swelling developing in the area which is normal and will reduce within a short time)
