Such as nerve damage, jaw distortion, etc. So to understand more about wisdom teeth as well as complications after wisdom tooth extraction, let’s find out in detail with My Aurid through the following article.
Why is it necessary to extract tooth number 8?
Tooth number 8 is also known as wisdom tooth – this tooth is “born late” on the jaw. When the jaw bone is fully developed and strong, at the age of 17-25, the wisdom tooth begins to move. However, there are some cases where these teeth grow earlier or later depending on each person’s constitution.
Depending on each person, the number of wisdom teeth that grow varies. Some people don’t grow teeth, some people only grow lower teeth, or only grow upper teeth.

During the teething process, wisdom teeth cause a lot of discomfort due to dull, prolonged pain. And the time it takes for wisdom teeth to grow is long, it can take several years to complete the tooth. During this time, teething people will experience pain and difficulty chewing. Along with that, there are wisdom teeth that grow crookedly, grow obliquely, etc., which further affects oral health, increases disease, puts pressure on the important 7th molar, hinders chewing, etc. Therefore, removing tooth number 8 as soon as possible will be better for oral health.
Is wisdom tooth extraction dangerous?
There is quite a lot of interest and worry because nowadays not only word of mouth information but social networking sites also report a lot of news. about complications of wisdom tooth extraction. It is known that wisdom teeth are the last molars, although they do not ensure important functions, they can be removed, but the location of the teeth along with the connection to the nerves makes the extraction of this tooth even more difficult.
For wisdom tooth extraction to be safe and to prevent complications after wisdom tooth extraction, it is a combination of many factors from the doctor, the dental facility, the extraction conditions, and the eating and hygiene of the person having the tooth extracted. According to doctors, tooth number 8 extraction is not dangerous if performed at reputable dental facilities, with proper technique and procedure.
In particular, the conditions of the clinic and tooth extraction area must be sterile,Modern sterilization tools, machinery and equipment to support tooth extraction, especially skilled doctors, good techniques, rich in expertise and experience. On the contrary, it will be difficult to avoid complications after tooth number 8 is extracted, which will greatly affect oral health.

Complications after tooth extraction wisdom
As mentioned, improper extraction of tooth number 8, poor force control, poor clinic conditions,… will cause complications when removing wisdom teeth. Specifically as follows:
Causing nerve damage
The lower dental nerve is usually located close to the lower wisdom tooth root. The role of these nerves is to provide sensation to the dental arches, gums and lower lip. If the doctor uses too much force or the nerve is located too close without the doctor detecting it, it will easily cause damage, leading to numbness and dysesthesia in the lips.
Infection at the tooth extraction site
In addition to the doctor’s skills, after tooth number 8 is extracted, the important thing to follow is oral care and hygiene. If a tooth is extracted in a poor quality, non-sterile or poorly hygienic environment, the tooth socket will become infected. This causes sequelae after wisdom tooth extraction: pain and swelling, prolonged bleeding, difficulty swallowing, difficulty opening the mouth, etc. More dangerously, if not treated and resolved early, the infection can cause septicemia, leading to death.
Damage to tooth number 7
Tooth number 8 grows next to tooth number 7 – tooth number 7 is an important molar on the jaw, responsible for the main function of chewing and tearing food. Removing tooth number 8 does not affect oral function, but when tooth number 7 is lost, chewing will be impaired, jaw misalignment, jaw bone loss, etc. Therefore, teeth number 8 that grow tilted, grow crookedly, or grow into tooth number 7 must be removed early. However, if the doctor is not experienced enough, has poor skills, pulls the tooth incorrectly, or uses too much force, it will also affect tooth number 7. This makes tooth number 7 sensitive, painful, chipped, and even loose.

Rupturejaw bone
Using too much force to extract wisdom teeth also causes complications of jaw bone fracture with the following symptoms: swelling, pain and prolonged bleeding. Besides, this painful swelling can also come from a dry socket. Dry socket occurs when the blood clot does not form in the tooth hole or breaks off too early.
Perforation of the maxillary sinus
This complication after wisdom tooth extraction often occurs when the upper wisdom tooth is extracted. Because the maxillary sinus is a hollow structure, located close to the root of tooth number 8, only separated by a thin bone plate. Perforation of the maxillary sinus is a dangerous complication after wisdom tooth extraction that requires X-rays to determine the condition and come up with an appropriate treatment plan.
Tooth root extraction
After tooth number 8 is extracted, there may be bleeding and pain, but it only happens for a few hours or a few days. If this condition persists, an X-ray is needed to determine whether there is infection or residual tooth root after wisdom tooth extraction.
Anesthetic poisoning
Complications after wisdom tooth extraction that are also common and dangerous are anesthetic poisoning. Although anesthetics are allowed for medical use, they must be controlled in appropriate amounts to ensure safety. If the doctor is less experienced and cannot control the amount of medicine, causing the concentration of medicine in the blood to exceed the allowable level, it can cause poisoning. At this time, the person having the tooth extracted may have convulsions all over the body, difficulty breathing, purple streaks on the whole body, etc.
In general, complications from wisdom tooth extraction are dangerous and greatly affect oral and physical health. Therefore, choosing a reputable dental facility and address is essential and after tooth extraction, monitoring the signs and taking proper oral care is very important.
