Tooth extraction is the complete removal of one or more teeth from your mouth. Depending on the conditions of your teeth, your dentist may suggest the pull-out method or dental surgery for the extraction. Dentists generally prefer to keep your natural teeth intact, but sometimes the damage rate is too high, or your teeth are so much decayed that extraction is the only way out. The whole process is carried out under the influence of local anesthetics, so you would not feel any pain. But you experienced some discomfort after the procedure.
A bone graft is a minor surgical procedure that helps to build up your jaws in case it is too thin or too soft. The procedure uses processed bone materials, and once it is done, your body will start depositing natural bone cells around it. As the natural deposits start growing gradually, the graft material will get completely replaced.
