What is Tooth Extraction?


Tooth extraction is the process of pulling out a tooth or teeth which is decayed beyond any repair or treatment.

Why Tooth Extraction
Your dentist will recommend tooth extraction under any one of the below mentioned circumstances:

• Repairing a damaged tooth is not practical in cases such as –

• Broken, cracked, or extensively decayed teeth

• Teeth that are not suitable candidates for root canal treatment

• Teeth associated with advanced periodontal disease (i.e., gum disease)

• Mal-positioned or non-functional teeth (e.g., wisdom teeth)

• Preparation for orthodontic treatment (e.g., braces or other alternatives such as Six Month Smiles treatment)

Tooth Extraction Procedure

Following is the common procedure that is followed worldwide for tooth extraction:
1. A cotton bud soaked in anaesthetics is rubbed round the tooth to be extracted on both the side front as well as back.

2. After a little wait, your dentist will start pushing a series of anaesthetics injections around the tooth to be extracted. A little bit of pain may be experienced while injecting.

3. After a while, another series of deeper anaesthetics injections are applied around the tooth to be extracted and if there is a tooth abscess, an injection will likely be placed into the abscess – which is extremely painful.

4. If the dentist is caring then there will be another few deep anaesthetics injections to make the area numb.

5. A small wait, then the dentist starts to peel down the gum from the tooth to be extracted, so that no flesh is left attached to the tooth - prevents the flesh being torn from the tooth when the tooth is extracted.

6. The dentist uses a pair of purpose built pliers to grip the tooth to be extracted, then starts rotating the tooth. This process is repeated till the tooth is ready to be pulled out at ease.

7. Once the tooth is extracted the dentist will then clean up the area, squeeze the area hard to remove any puss, push the loose gum tissue into the hole that's left and possibly crush the tooth socket to promote a firmer area - to encourage good healing.

8. The dentist will place a wet cotton gauze, rolled up, across the hole left by the tooth being extracted, asking you to bite down on it hard for the next 30 minutes, so as to encourage a solid blood clot to form. Being wet beforehand, the cotton gauze should leave the blood clot intact in the hole when the gauze is lifted out at home by your self.

Post Treatment Effect

Long Term problems from extracting a tooth:
• Once a tooth is extracted other teeth may tilt into where the tooth was extracted from, thereby making eating difficult and teeth that tilt to fill the gap are at greater risk of tooth decay. The tilt is normally forwards.

• In case of front tooth, extraction may result in adverse cosmetic appearance of the mouth.

• If it was a molar that was removed, chewing food may be difficult to achieve, particularly if it was a large molar that made up a large section of the chewing area.

• Further it may create problem while chewing food like bread crust or an apple, pieces can be pushed down into the extraction socket by the tooth opposing it, causing pain.

• Another long term problem is thinning of the jaw bone, particularly when several teeth have been extracted.

• If a nerve is damaged during a tooth extraction, it will likely to heal in several weeks to a couple of years and sometimes even the nerve will never recover fully. Symptoms can include loss of feeling - numbness - and tingling in any of the parts of the mouth, including the tongue.

Pros and cons of Tooth Extraction
Pros Cons

Food and bacteria will hover around the wisdom teeth and surrounding teeth as well. Since it is difficult to remove the debris from the area, it finally results in tooth decay.
Wisdom tooth extraction is not a chosen method of treatment while presently suffering from an infection. Wisdom tooth extraction should be done after all infection subsides.
Sometimes wisdom teeth are only partially erupted leaving the surrounding gums a collection pocket for bacteria and food particles, a perfect foundation to initiate a gum infection which can easily spread to the cheek and even the neck When post-op instructions are not properly followed, post surgical problems like bleeding, swelling, and additional pain will be experienced by the patient.
An eruption of a wisdom tooth will shift other teeth and cause mal positioning. When tooth becomes crooked it is not advisable to go for smile design. After the wisdom tooth extraction, a dry socket condition may appear which is a blood clot formed in the area of extraction, only to dislodged and expose the vulnerable bone lying below. This painful condition would most likely occur from not following post-op instructions.
The wisdom tooth can become abscessed or an infectious cyst may form around the wisdom tooth, especially since hygiene in the area is more difficult.
For individuals needing dentures at some point, wisdom teeth should first be removed.
