What is an Extraction?
A tooth extraction, is the removal of a tooth from its socket in the bone.
What it is used for
If a tooth has been broken or damaged by decay, your dentist will try to fix it with either a filling, crown or other treatment. In some cases that there's too much damage for the tooth to be repaired, the tooth needs to be extracted.
How it's done
There are two different types of extractions:
Simple extraction, is performed on a tooth that can be seen in the mouth. Most dentists commonly do simple extractions. In a simple extraction, the dentist will loosen the tooth with an instrument called an "elevator". The dentist then, uses an instrument called a "forceps" to remove the tooth.
Surgical extraction, is a more complex procedure. This is done if a tooth may have broken off at the gum line or has not come into the mouth yet. Surgical extractions are normally done by oral surgeons. However, they are also done by some general dentists.
Normally simple extractions can be done using just an injection( a local anesthetic). You may or may not receive a prescription to help you relax. For a surgical extraction, you will receive a local anesthetic, and you may have anesthesia through a vein (intravenous) if you go to an oral surgeon. Some people who might need general anesthesia includes, patients with specific medical or behavioral conditions and young children.
