Wisdom teeth

Wisdom teeth are third molars that usually appear between the ages of 17 and 24 (although they may appear when older, younger, or may not appear at all). They are commonly extracted when they affect other teeth—this impaction is colloquially known as "coming in sideways." [1] Most people have four wisdom teeth, but it is possible to have more or fewer. Absence of one or more wisdom teeth is an example of hypodontia. Any extra teeth are referred to as supernumerary teeth.[2][3]

 

Etymology

They are generally thought to be called wisdom teeth because they appear so late—much later than the other teeth, at an age where people are supposedly wiser than as a child, when the other teeth erupt. The English wisdom tooth is derived from Latin dens sapientiae. The same root is shared by German Weisheitszahn, Dutch verstandskies, Belgian-Dutch wijsheidstand, Norwegian visdomstann, Danish and Swedish visdomstand, Finnish viisaudenhammas, French dent de sagesse, Portuguese dente do juízo, Spanish muela del juicio or muela cordal, Italian dente del giudizio, Romanian masea de minte, Croatian and Serbian umnjaci, Hungarian bölcsességfog, Czech zuby moudrosti, Polish zęby mądrości, Russian зубы мудрости, Bulgarian мъдрец (meaning wise man), Estonian tarkusehammas and Hebrew שן בינה. There exists an interesting Dutch folk etymology that the Dutch word verstandskies is derived from "far-standing" (ver-staand) molar, and that mistranslations of the Dutch word (in which verstand translates to wisdom) are the root for corresponding words in other European languages.

Turkish language refers directly to the age at which wisdom teeth appear and calls it 20 yaş dişi (20th year tooth). In Korean, its name is Sa-rang-nee (사랑니, love teeth) referring to the young age and the pain of the first love. In Japanese, its name is Oyashirazu (親知らず), literally meaning "unknown to the parents" from the idea that they erupt after a child has moved away from home.

 

Impactions

The upper left (picture right) and upper right (picture left) wisdom tooth are distoangularly impacted. The lower left wisdom tooth is horizontally impacted. The lower right wisdom tooth is vertically impacted (unidentifiable in orthopantomogram).
The upper left (picture right) and upper right (picture left) wisdom tooth are distoangularly impacted. The lower left wisdom tooth is horizontally impacted. The lower right wisdom tooth is vertically impacted (unidentifiable in orthopantomogram).

Impacted wisdom teeth fall into one of several categories. Mesioangular impaction is the most common form (43%), and means the tooth is angled forward, towards the front of the mouth. Vertical impaction (38%) occurs when the formed tooth does not erupt fully through the gum line. Distoangular impaction (6%) means the tooth is angled backward, towards the rear of the mouth. And finally, Horizontal impaction (3%) is the least common form, which occurs when the tooth is angled fully ninety degrees forward, growing into the roots of the second molar.

Typically distoangular impactions are the easiest to extract in the maxilla and most difficult to extract in the mandible, while mesioangular impactions are the most difficult to extract in the maxilla and easiest to extract in the mandible.

Impacted wisdom teeth may also be categorized on whether they are still completely encased in the jawbone. If it is completely encased in the jawbone, it is a bony impaction. If the wisdom tooth has erupted out of the jawbone but not through the gumline, it is called a soft tissue impaction.

Sometimes the wisdom tooth has failed to erupt completely through the gum bed and the gum at the back of the wisdom tooth extends over the biting surface, forming a soft tissue flap or lid around the tooth called an operculum. Teeth covered by an operculum can be difficult to clean with a toothbrush. Additional cleaning techniques can include using a needle-less plastic syringe to vigorously wash the tooth with moderately pressured water or to softly wash it with hydrogen peroxide.

However, debris and bacteria can easily accumulate under an operculum, which may cause pericoronitis, a common infection problem in young adults with partial impactions that is often exacerbated by occlusion with opposing 3rd or 2nd molars. Common symptoms include a swelling and redness of the gum around the eruption site, difficulty in opening the mouth, a bad odor or taste in the mouth, and pain in the general area which may also run down the entire lower jaw or possibly the neck. Untreated pericoronitis can progress to a much more severe infection.

If the operculum does not disappear, recommended treatment is extraction of the wisdom tooth. An alternative treatment involving removal of the operculum, called operculectomy has been advocated. There is a high risk of permanent or temporary numbness of the tongue due to damage of the nerve with this treatment and is no longer recommended as a standard treatment in oral surgery.

Main article: Extraction (dental)

A wisdom tooth is extracted to correct an actual problem or to prevent problems that may come up in the future. Wisdom teeth are extracted for two general reasons: either the wisdom teeth have already become impacted, or the wisdom teeth could potentially become problematic if not extracted. Potential problems caused by the presence of properly grown-in wisdom teeth include infections caused by food particles easily trapped in the jaw area behind the wisdom teeth where regular brushing and flossing is difficult and not effective. Such infections may be frequent, and cause considerable pain and medical danger. Another reason to have a wisdom tooth removed is if the tooth has grown in improperly, causing the tongue to brush up against it. The tongue can tolerate it for a limited time, until it causes a painful sensation, to the point where the sheer pain can numb the tongue affected, and the area around it (part of the lips, and the cheek). The numbness feels similar to the feeling of anesthesia, possibly meaning a nerve can be affected by the wisdom tooth improperly growing in. Also, it is a wise choice to have them removed if undergoing extensive orthodontic work because once the teeth have come in they could inflict some damage on expensive straightening.

The extraction of wisdom teeth can be a simple, but also a difficult surgical procedure, and should only be performed by dental professionals with proper training and experience performing such extractions. The precise reasons why an individual’s wisdom teeth need to be extracted should be explained to them by their dentist, after an examination which almost certainly will need to include x-rays.

 

Post-extraction problems

There are several problems that can manifest themselves after the extraction(s) have been completed. Some of these problems are unavoidable and natural, while others are under the control of the patient. The suggestions contained in the sections below are general guidelines that a patient will be expected to abide by, but the patient should follow all directions that are given by the surgeon in addition to the following guidelines. Above all, the patient must not disregard the given instructions; doing so is extremely dangerous and could result in any number of problems ranging in severity from being merely inconvenient (dry socket) to potentially life-threatening (serious infection of the extraction sites).

 

Bleeding and oozing

Bleeding and oozing is inevitable and should be expected to last up to three days (although by day three it should be less noticeable). Rinsing out one's mouth during this period is counter-productive, as the bleeding stops when the blood forms clots at the extraction sites, and rinsing out the mouth will most likely dislodge the clots. The end result will be a delay in healing time and a prolonged period of bleeding. However, after about 24 hours post-surgery, it is best to rinse with lukewarm saltwater to promote healing. This should be done every 2 hours until the swelling goes down and every 4-6 hours after that for at least a week. Gauze pads should be placed at the extraction sites, and then should be bitten down on with firm and even pressure. This will help to stop the bleeding, but should not be overdone as it is possible to irritate the extraction sites and prolong the bleeding. The bleeding should decrease gradually and noticeably upon changing the gauze. If the bleeding lasts for more than a day without decreasing despite having followed the surgeon's directions, the surgeon should be contacted as soon as possible. This is not supposed to happen under normal circumstances and signals that a serious problem is present.

Due to the blood clots that form in the exposed sockets as well as the abundant bacterial flora in the mouth, an offensive smell may be noticeable a short time after surgery. The persistent odour often is accompanied by an equally rancid-tasting fluid seeping from the wounds. These symptoms will diminish over an indefinite amount of time, although one to two weeks is normal. While not a cause for great concern, a post-operative appointment with your surgeon seven to ten days after surgery is highly recommended to make sure that the healing process has no complications and that the wounds are relatively clean. A plastic syringe (minus the hypodermic needle) full of a mixture of equal parts hydrogen peroxide and water or chlorhexidine gluconate should be gently plunged into the sockets to remove any food or bacteria that may collect in the back of the mouth.

 

Dry socket

Main article: dry socket

A dry socket is the event where the blood clot at an extraction site is dislodged, falls out prematurely, or fails to form. In some cases, this is beyond the control of the patient. However, in other cases this happens because the patient has disregarded the instructions given by the surgeon. Smoking, spitting or drinking with a straw in disregard to the surgeon's instructions can cause this. The extraction site will become irritated and pain will manifest at one level or another. The patient should contact his surgeon if they suspect that they have a case of dry socket; the surgeon can prescribe medication in topical form to apply to the affected site. If this is done, dry socket becomes merely an annoyance, but without the medication dry socket can progress to an infection of the extraction site.

 

Swelling

Swelling should not be confused with dry socket; although painful, swelling should be expected and is a sign that the healing process is progressing normally. There is no general duration for this problem; the severity and duration of the swelling vary from case to case. The instructions the surgeon gives the patient will tell the patient for how long they should expect swelling to last, including when to expect the swelling to peak and when the swelling will start to subside. If the swelling does not begin to subside when it is supposed to, the patient should contact his or her surgeon immediately. While the swelling will generally not disappear completely for several days after it peaks, swelling that does not begin to subside or gets worse may be an indication of infection. Swelling that re-appears after a few weeks is an indication of infection caused by a bone or tooth fragment still in the wound and should be treated immediately.

 

Nerve injury

This is primarily an issue with extraction of third molars, but can occur with the extraction of any tooth should the nerve be in close proximity to the surgical site. Two nerves are typically of concern and are found in duplicate (on the left and right side):

  • The inferior alveolar nerve, which enters the mandible at the mandibular foramen and exits the mandible at the sides of the chin from the mental foramen. This nerve supplies sensation to the lower teeth on the right or left half of the dental arch, as well as sense of touch to the right or left half of the chin and lower lip.
  • The lingual nerve, which branches off the mandibular branches of the trigeminal nerve and courses just inside the jaw bone, entering the tongue and supplying sense of touch and taste to the right and left half of the anterior 2/3 of the tongue as well as the lingual gingiva (i.e. the gums on the inside surface of the dental arch).

Such injuries can occur while lifting teeth (typically the inferior alveolar) but are most commonly caused by inadvertent damage with a surgical drill. Such injuries are rare and are usually temporary, but depending on the type of injury (i.e. Seddon classification: neuropraxia, axonotmesis, and neurotmesis) they can be prolonged or even permanent.

 

Treatment controversy

Preventive removal of the third molars is a common practice in developed countries despite the lack of scientific data to support this practice. In 2006, the Cochrane Collaboration published a systematic review of randomized controlled trials in order to evaluate the effect of preventative removal of asymptomatic wisdom teeth[4]. The authors found no evidence to either support or refute this practice. However, there was reliable evidence showing that preventative removal did not reduce or prevent late incisor crowding. The authors of the review suggested that the number of surgical procedures could be reduced by 60% or more.

Likewise, ClinicalEvidence published a summary [5], largely based on the Cochrane review, that concluded prophylactic extraction is "Likely to be ineffective or harmful". ClinicalEvidence offered the following details:

"While it is clear that symptomatic impacted wisdom teeth should be surgically removed, it appears that extracting asymptomatic, disease-free wisdom teeth is not advisable due to the risk of damage to the inferior alveolar nerve."
"Some non-RCT evidence suggests that extraction of the asymptomatic tooth may be beneficial if caries are present in the adjacent second molar, or if periodontal pockets are present distal to the second molar."
