A dental extraction is also referred to as tooth extraction, exodontia, or exodontics. It’s also informally known as tooth pulling. Extraction is a procedure of the removal of teeth from the dental alveolus (socket) in the alveolar bone.
Extractions are widely performed for various reasons but are most commonly done for things like irreversible decay of the tooth, infection, periodontal disease, or dental trauma.
For adults, wisdom teeth that are impacted are unable to grow normally into the mouth. This may cause recurrent infections of the gum, which is known as pericoronitis. In some cases, if the teeth are crowded, sound teeth can be extracted to create space so that the rest of the teeth can be straightened.
Dentists and oral surgeons can perform tooth extractions. Before removing the tooth, the dentist injects a local anesthetic to numb the affected area. If there is more than one tooth extracted or a tooth is impacted, then the dentist may use a general anesthetic to prevent pain throughout your body so that you can sleep throughout the procedure.
There are two procedures for extractions of teeth:
(a) Simple nonsurgical extractions
(b) Surgical extractions.
SIMPLE NON-SURGICAL EXTRACTIONS
In simple nonsurgical extractions, the gum tissues are separated from the tooth. Special instruments are then used to make movement of the roots within the socket in the bone where the roots are.
Following this accomplishment to the degree possible, extraction forceps are placed on the tooth for further movement until the roots of the tooth are loose enough to allow for tooth extraction.
Surgical extractions involve the principle of root removal, although the gum tissue may have to be surgically moved away and some bone may have to be removed to get access to the roots.
The tooth has to be sectioned into several pieces to permit root removal. In this case, sutures are often placed to adapt the gum to the ridge and control postoperative bleeding.
