A dental extraction is the process of removing a tooth from the mouth. There are many different reasons for the need to remove teeth. The most common reason for extraction is tooth damage due to breakage or decay, that leaves the tooth beyond repair. Other reasons for extracting teeth include: dental abscess, pain, impaction of the tooth and periodontal disease.
X-rays are necessary for extracting teeth so the doctor can evaluate the shape of the tooth and location of surrounding structures, that could create potential complications. After the diagnosis has been made, local anesthetic will be given, so the area is completely numb.
The doctor will then gently lift the tooth from its socket in the bone. The majority of the time the tooth can be removed with relative ease, but occasionally, the tooth or tooth roots might require surgical extraction. If a patient is anxious about the procedure, extractions can be done under the influence of an oral sedative, IV sedation or nitrous oxide sedation, also called laughing gas.
