Tooth extraction

What are the possible causes for tooth extraction?

Although permanent teeth can last a lifetime, sometimes extractions may become necessary for a number of reasons. Teeth that have become damaged or decayed may need to be removed or extracted.

Other reasons for extraction may include:

A crowded mouth

Dentists may extract teeth to prepare the mouth for orthodontics. The aim of orthodontics is to correct teeth and jaws that are positioned improperly in the mouth. For example, people getting braces may require tooth extraction to create room for the teeth that are being moved into place. Similarly, some people have extra teeth that block other teeth from coming in. In such cases, your dentist may recommend extraction.


If tooth decay or damage reaches down to the pulp, the central part of the tooth containing nerves and blood vessels, bacteria in the mouth will enter the pulp, giving rise to infection. If infection is so extreme that antibiotics do not cure it, extraction may be needed to prevent the infection from spreading.

Risk of infection

Some teeth run a high risk of becoming a source of infection, if your immune system is compromised. For instance, people with organ transplants have a high risk of infection because they must take drugs that suppress the immune system. In such cases teeth may need to be extracted.

Gum disease

If periodontal disease- an infection of the tissues and bones that surround and support the teeth- have caused loosening of the teeth, tooth or teeth extraction may become necessary.

Delayed tooth fallout

Sometimes baby teeth don’t fall out in time to allow the permanent teeth to come in.


Your dentist  will perform the tooth extraction . Before removing the concerned tooth, the dentist will numb the area where the extraction needs to be performed, by injecting with local anaesthesia. If you are having several or more than one extractions, your dentist may use a general anaesthetic, this will prevent pain throughout your body and put you to sleep through the procedure. If the tooth is infected, the dentist will cut away gum and bone tissue that cover the tooth and then, using forceps, grasp the tooth and gently move it around in its socket to loosen it from the jaw bone and ligaments holding it in place. Sometimes, a tooth that is difficult to remove may need to be taken out in pieces.

Once the tooth has been extracted , you’ll be asked to bite on a piece of gauze for a few minutes. This pressure will allow the blood to clot. Typically, there will be minor bleeding for the next 24 hours or so. It should stop after that. In some cases, the dentist may even place a few stitches – usually self-dissolving – to close the gum edges over the extraction site.

After this procedure you are advised to eat soft food for a few days. In some cases, the blood clot in the socket may break loose, exposing the socket – causing a painful condition called dry socket. If this happens, your dentist will probably place a special dressing over the socket for a few days to protect it as a new clot forms.
