Tooth extraction is a process of removing or uprooting a tooth which is decayed, damaged beyond repair, or a removing a tooth where the tissues and bones are completely damaged.
Extraction can be done under the following circumstances:
In some cases when the root canal treatment cannot be performed then tooth extraction is carried out. There are some teeth that may require treatment of the nerve space that lies within them. While most teeth typically are candidates for root canal treatment, there can be complicating factors that remove this option and the dentist has no options other than tooth extraction in order to make a tooth repair.
Sometimes tooth extraction can be done for the ones which are mal-positioned and create constant irritation to the patients. For example, wisdom tooth which is a constant source of irritation to the person's cheek can be removed by tooth extraction.
Impacted teeth are often extracted. These are teeth with jaw bone positioning that cannot erupt into normal alignment. So by definition, impacted teeth are mal-positioned, precisely why they are often non-functional. This combination of factors makes impacted teeth common candidates for extraction.
In orthodontic treatment, the dentist is trying to perfect the alignment of the patient's teeth. But they can only do so within the confines of the person's jaw. Especially in cases where a large discrepancy exists between the size of the patient's jaws and the space needed for the improved teeth alignment. Therefore, some strategically located teeth may need to be extracted.
Using local anesthesia, a tooth can be extracted easily. Dentists use a special tool called elevator to loosen the tooth to be extracted by widening the space in the bone. Once the tooth is loosened, it can be pulled out with forceps.
In cases where the tooth is exposed and appears to be easily removable in one piece, local anesthesia is used for numbing the area to be affected of the tooth. Most dentists or oral surgeons use an instrument called an elevator to loosen the tooth, widen the space in the underlying bone, and break the tiny elastic fibers that attach the tooth to the bone. Once the tooth is dislocated from the bone, it can be lifted and removed with forceps.
In case of a difficult extraction, a general dentist may refer the patient to an oral surgeon. Oral surgeons are specialists trained to administer nitrous oxide (laughing gas), an intravenous sedative, or a general anesthetic to relieve pain. Extracting an impacted tooth or a tooth with curved roots typically requires cutting through gum tissue to expose the tooth. It may also require removing portions of bone to free the tooth. Some teeth must be cut and removed in sections. The extraction site may or may not require one or more stitches (sutures) to close the incision.
