\n\t Wisdom teeth (eights, third molars) are the last units on each side of the tooth row. They are the last to erupt when the dentoalveolar system is fully formed. And in most cases, their appearance causes a lot of problems. Since they often do not have enough space in the row, they grow incorrectly: at an angle, sideways, horizontally, interfere with neighboring units, traumatize the mucosa of the cheeks, tongue.<\/p>\n

\n\t Whether it is necessary to remove wisdom teeth – depends on the clinical situation. The doctor will not remove the third molars “just in case”. There must be medical indications for this. The anatomy of the eights is more complex, they are the largest units in the row with a developed root system. Although they belong to the chewing group of teeth, they do not take part in the process of chewing, this function of the units is weakened or absent. The primary function of the third molars is to keep the teeth in the row from moving apart.<\/p>\n

What problems can arise<\/h2>\n

\n
• In almost 80% of cases<\/i>, the eruption of third molars is accompanied by various purulent-inflammatory processes. A mucous hood<\/b> is formed over the erupting unit, a pocket is created around it, where bacterial plaque accumulates, food residues, which leads to purulent inflammation – pericoronaritis<\/i>.<\/li>\n
• Often the eights grow towards the tongue, cheek, palate, constantly traumatizing the mucosa, delivering a lot of painful, discomforting sensations. Chronic trauma to soft tissues<\/b> can lead to the formation of ulcers, erosions, the development of leukoplakia (hyperkeratosis) – on the traumatized area of the mucosa becomes more dense. If the cause (traumatic tooth) is not eliminated, there is a risk of neoplasm (including malignant).<\/li>\n
• Between 8 and 7 (on the contact surfaces) a carious cavity is formed<\/b> where food is constantly clogged, contributing to the rapid development of caries. The carious process affects not only the eight, but also the 7 molars, which are important for the dentoalveolar apparatus. In case of interdental caries it is necessary to remove the wisdom tooth, and the seventh molar should be treated qualitatively.<\/li>\n
• Sometimes the eighth molar is located horizontally in the gum, rests on the root of the neighboring tooth, traumatizes it, provokes the formation of a cyst<\/b>. Such pathology in the worst case scenario can even lead to resection of the jawbone. As a result of a long asymptomatic period, cysts can acquire significant size, damage the surrounding bone tissues, neighboring units.<\/li>\n
• Wisdom teeth can exert serious pressure on neighboring units, shifting them out of place. This pressure is transmitted to all teeth, provoking deformities of the row<\/b>, bite disorders, periodontal disease.<\/li>\n<\/ul>\n

  In what cases the wisdom tooth is extracted<\/h2>\n

  \n\t The most common indication for surgical removal of third molars is their abnormal position<\/b> alebo difficult eruption<\/b>. In many cases, they remain inside the jawbone for a very long time, having difficulty erupting to the surface, causing many problems. In these clinical situations, the oral surgeon performs a rather complex surgery to extract the tooth unit from the bone tissue.<\/p>\n

  \n\t The reasons why wisdom teeth are removed are many. A direct indication for surgical extraction of the eight is:<\/p>\n

  \n
  • hygiene of the third molars is difficult or impossible;<\/li>\n
  • decay, crown decay;<\/li>\n
  • retained molars (not erupted partially or completely);<\/li>\n
  • displacement of teeth in the row due to the growth of eight teeth;<\/li>\n
  • dystopia (misalignment of the eight in the row) or traumatic occlusion;<\/li>\n
  • Difficult access when treating neighboring units;<\/li>\n
  • inclined positioning, contributing to distortion, destruction of neighboring units;<\/li>\n
  • eruption beyond the boundary of the tooth row;<\/li>\n
  • wisdom tooth roots growing into the maxillary sinus;<\/li>\n
  • eruption of the eight caused complications (facial neuralgia);<\/li>\n
  • incomplete eruption with the presence of a hood of gingival mucosa.<\/li>\n<\/ul>\n

    \n\t Often the extraction of wisdom teeth is carried out for orthodontic indications, when due to their abnormal position begins to shift the entire row – shifting quadruplets, incisors, forming crowding of the front group of dental units. When braces are removed wisdom teeth to reduce the period of correction, to exclude complications if the eights begin to erupt during treatment.<\/p>\n

    Why remove a wisdom tooth<\/h2>\n

    \n\t Third molars are rarely retained – they deteriorate early or extraction is necessary for the proper functioning of the tooth row. Most dentists prefer to remove the abnormal 8 before they can seriously damage the health of the jaw (especially the lower jaw) to the entire row.<\/p>\n

    \n\t<\/p>\n

    \n A<\/b> wisdom tooth should not be extracted<\/b> when the 6th and 7th molars are missing. Contraindication to extraction is inflammation of the periodontium, root, bone or gingiva, because there is a risk of spreading and aggravation of the pathological process against the background of the postoperative wound. The limitation to surgical extraction of third molars is:<\/p>\n

    \n
    • 8 location in the area of malignant formation;<\/li>\n
    • pregnancy;<\/li>\n
    • hypertension of II-III degree;<\/li>\n
    • heart attack, stroke suffered less than 3 months ago.<\/li>\n<\/ul>\n
