The second method is reserved for those teeth which are not erupted (impaected), those teeth whose roots either cannot be gripped using the forceps or the roots are of odd shape and defy all efforts to remove them by using forceps. In this method, the gums are cut open and the bone around the tooth is cut to allow removal of the teeth 

Extractions are done after administration of local anesthesia that makes the tooth and the surrounding tissues numb. Thus extraction procedure generally are not painful. But a feeling of pressure may be experienced by the patient during the procedure.

The wisdom teeth are often inside the bone and therefore cannot be removed easily by using the forceps. In addition their position and angulation may be abnormal. They often require surgical extraction by cutting open the overlying gums and cutting the bone around the teeth.

Some extractions are followed by appearance of swelling. There is nothing to worry about, as it is a part of normal healing process. In reaction to the extraction, the tissues show an inflammatory reaction to heal the wound created by the removal of the tooth. Swelling is a part of the normal inflammatory process. However the dentist may advice you to have cold fomentation over the area to reduce the swelling. 

Sutures are stitches which maybe given after an extraction. These stitches help in approximating the gums and therefore restrict the size of the wound. Sutures also help in controlling the bleeding.

Sutures are of two types: absorbable and non-absorbable. The absorbable sutures are broken down by the enzymes in the human body. So they just dissolve in a few days and need not be removed. The non-absorbable sutures need to be removed after 7-10 days.   

Local anesthesia is temporary loss of sensation to pain and other sensations such as pressure, temperature and touch in a localized area. This is done by injecting a local anesthetic drug around the tooth being extracted. This numbness lasts for a few hours. Most extractions are done under local anesthesia.   

General anesthesia is reversible loss of consciousness along with loss of all sensation. General anesthetic drugs also help in controlling pain and relax the muscles of the body. General anesthetics are used in complicated surgical procedures that may take a long duration and when the surgery is done in multiple sites. They are also useful in unco-operative patients.         

The dentist must be informed of any medical problems that you may have or had in the past. There are certain systemic problems, which may require certain precautions during the dental treatment so as to avoid complications. In some cases the dentist may require consent from your physician before he can extract. Some of the systemic conditions are mention below.

Usually extractions may not pose any problems for heart patients. However the dentist may require your physician's consent. Patient is Advised to Stop any Antiplatelet drugs (Aspirin) Prior to any Procedure. In addition prophylactic antibiotics may be prescribed prior to the extraction as a precautionary measure.

Patients who have their diabetes under control by diet and medication can undergo extraction. However the dentist may give you a prophylactic antibiotic prior to the procedure. He would also advice you to have normal food and medicine before the appointment. 

A tumor is uncontrolled duplication of certain cells in the body. Tumors are of 2 types - benign and malignant. Benign tumors are relatively harmless while the malignant tumors are serious and tend to spread to nearby and far tissues and pose a threat to life.

Oral cancers can occur due to a number of factors such as chewing of tobacco and betel nut, excessive alcohol intake, smoking, tissue irritation from sharp tooth or ill fitting denture etc.

Most oral cancers may appear as a swelling or painless ulcer. Sometimes a patch of whitish tissue or red tinged tissue may be seen. Pain is usually a feature in the late stages due to infection of the lesion. The cancer can spread to nearby and far tissues.     

1. Chemotherapy: This means the tumors are treated by drugs or chemicals that kill the tumor cells. These drugs are usually very toxic to the body.
2. Radiation therapy: The tumor is exposed to radiation, which is found to cure certain tumors.
3. Surgical removal: The entire tumor is removed along with a border of normal tissue. In case the tumor has spread to nearby lymph glands, they may also be removed surgically.                         

They are certain lesions of the oral tissue that show an increased risk of transforming into malignant oral cancer. These lesions are called precancerous lesions. The dentist will try and determine what type of lesion it is and take treatment measures so as to prevent malignancy from developing.
