Wisdom teeth: wise or foolish?

Wisdom teeth are the common name of the 8 teeth, or the 3rd molar, usually appear on your arch after 16 years. The wisdom tooth removed should be conducted by a specialist oral, especially those trapped or grow under gums.

So far, except those wisdom teeth need to be extracted because they grow underneath or implicit, those wisdom teeth growing straight are not identified whether this tooth can cause complications or not? Some dentists recommend removing wisdom teeth even when teeth are not offensive to you. Although there are different views, but you should understand the benefits or disadvantages that may occur while retaining or removing wisdom teeth.



These disadvantages can occur when retain wisdom teeth:

  1. Cover wisdom teeth gingivitis: A very common infection during teething. The disease manifested by inflammation of gums around the wisdom tooth surface.

Some more severe cases can lead to inflammation of associated system causing face swelling. To solve this problem, some dentists recommend patient to cut that covering gums part, however gingivitis bosses often relapse after cutting.
  2. Inflammatory periodontal disease: It usually occurs on the wisdom teeth. According to statistics from countries like USA, UK, Germany..., alveolar bone and gums around wisdom teeth are vulnerable. If we measure periodontal pocket around this area, we can usually detect over 5mm deep pockets, especially in patients with poor oral hygiene, periodontal inflammation will develop easily.
  3. Cramped teeth: Commonly, when wisdom teeth stucked while teething, it will push those front teeth. Only a wisdom tooth is lower (rtrapped) can also pus 2 molars, 2 smaller molars and 1 small fang, eventually, causes tooth jammed at the front of jaw. To prevent this, removing wisdom teeth is necessary.
  4. Damage to other teeth: Wisdom teeth growth can damage the tooth in front of it. The trapped grow facilitate those stuffing food get stuck at No. 7 teeth surface and leads to tooth decay in this region. In addition, it also generates periodontal pockets in teeth face No. 7 (according to a survey in the United States, more than 30% have gum pockets around the teeth 5mm at No. 7 tooth in this case). For some rare cases, the wisdom teeth can cause tooth root atrophy nearby.
  5. Cellulitis: A severe complications with manifestations such as cheek swelling, skin tension, normal color or reddish, painful when touched. Patients surfer intense pains, difficult chewing, hard to open mouth, sometimes total freeze jaw; Can have fever, fatigue, cannot eat or sleep, if left untreated or not properly treated, the pus will drain out through a leak in the mouth.
  6. Whole-cell yeast: Rare and suitable treatment is to trim the jaw bone.


  1. There are enough teeth: Retaining wisdom teeth in place of its function, help person maintain healthy teeth and fully functioned jaws.
  2. Help prosthodontist: In the case of losing the 7th tooth, if wisdom tooth appears straight, it can be used as pillar for your dental restoration needs.
  3. Not endure a surgery: You will not have to undergo a minor surgery,  and no complications can occur.

  2. Inflammation of alveolar wisdom: The most common complication, occurring more in older patients, women are more susceptible than men. Inflammation accounts for around 1-5% of the total number of possible complications.
  3. Postoperative infection: It can happen, but much less.
  4. Nerves injury: Anesthesia lips, tongue numbness, usually temporary but sometimes can become permanently. If these issues last more than 6 months, they are considered permanent damage.
  5. Swelling of the face: It often happens, especially in the case of minor surgery when wisdom teeth misalign under gum and have to drill bone during surgery. This phenomenon will be eased if the patient compliance with post-operative instructions of your dentist.


  1. The younger patients are, the less complication they may face. Especially with those annoying wisdom teeth, they should be removed as soon as possible. The difficulty level as well as postoperative complications increases along with age.
  2. Time healing occurs faster in the case of the wisdom tooth root has not completed and the jaw bone has not been totally calcified. We truly hope that this calcification will help you get the right decision to keep or remove wisdom tooth. Even if your dentist does not know in advance whether your wisdom teeth can cause complications or not, they can advise you the current status of it, so please do not hesitate to visit and consult dentist.
