teeth, and<br>can be kept clean, there are cases where they can be kept and monitored.<br>On the other hand, if a wisdom tooth has only partially erupted or is positioned at an angle, causing repeated<br>inflammation of the surrounding gums, food impaction, or decay in the wisdom tooth or the adjacent molar,<br>extraction may be considered.<br>In particular, for lower wisdom teeth, there are cases where the relationship with the mandibular canal,<br>through which the inferior alveolar nerve runs, needs to be checked.<br>Today, I will introduce the case of a woman in her 20s who had a problem found around a wisdom tooth during a check-up,<br>had the positional relationship between the wisdom tooth and the inferior alveolar nerve canal checked with 3D CT,<br>and then had the tooth

20s.<br>She did not come because of pain in a particular tooth, but for an overall<br>oral check-up.<br>The examination showed wisdom teeth in both the upper and lower jaws, and the eruption status of each<br>and the condition of the surrounding tissue differed.<br>Some wisdom teeth were impacted in the gum, but there were no particular signs of inflammation or need for treatment at that time, so we decided to monitor them.<br>On the other hand, the lower right wisdom tooth was partially exposed in the mouth, and when we checked the surrounding gum condition and<br>the adjacent tooth, extraction needed to be considered.<br>The important point here is that we did not extract all the wisdom teeth just because they were there,<br>but evaluated the condition of each wisdom tooth

id=\"sec-2\" class=\"wp-block-heading has-text-align-center\" style=\"color:#0b9b3f;font-size:1.15rem\">Why can a partially erupted wisdom tooth be a problem?<\/h2>\n\n\n\n<p class=\"has-text-align-center wp-block-paragraph\">When a wisdom tooth has not fully erupted and only part of it is out of the gum,<br>it can be hard to clean around it with a toothbrush.<br>Food and plaque tend to collect between the wisdom tooth and the molar in front of it, and the surrounding gums<br>may become inflamed, or decay may develop in the wisdom tooth or the adjacent tooth.<\/p>\n\n\n\n<p class=\"has-text-align-center wp-block-paragraph\">For this patient as well, after checking the swelling of the gum around the wisdom tooth and the condition of decay in the adjacent area, we explained the need for extraction.<\/p>\n\n\n\n<p class=\"has-text-align-center wp-block-paragraph\">Typical cases in which wisdom tooth extraction is considered include repeated inflammation or pain around the wisdom tooth, decay, effects on adjacent teeth, and conditions that are difficult to keep clean.<\/p>\n\n\n\n<p class=\"has-text-align-center wp-block-paragraph\">However, having orthodontic treatment is not by itself a reason to extract every wisdom tooth,<br>and the orthodontic treatment plan and the position of the wisdom teeth must be evaluated together.<\/p>\n\n\n\n<figure class=\"wp-block-image size-large\"><img loading=\"lazy\" decoding=\"async\" width=\"704\" height=\"464\"

class=\"has-text-align-center wp-block-paragraph\">In this patient's case, if you look at the arrow,<br>the gum toward the molar is swollen<br>and you can see that the tooth is decayed.<br>If the wisdom tooth is not completely buried<br>and has only partially erupted, as in the photo,<br>the gum swells and food gets trapped toward the gum, making it hard to keep clean,<br>which can also affect the tooth in front of it!<\/p>\n\n\n\n<div class=\"sdc-case-banner\" style=\"background:#000;color:#fff;padding:28px 24px;text-align:center;margin:0 0 8px\"><div

class=\"has-text-align-center wp-block-paragraph\">Inside the lower jaw, there is the mandibular canal, through which the inferior alveolar nerve,<br>which is involved in sensation of the lip and chin area, runs.<br>When the root of a lower wisdom tooth is close to the mandibular canal, it is important to check the<br>positional relationship between the two structures before extraction.<br>A panoramic X-ray helps us check the overall direction and position of the wisdom tooth,<br>but because it is a two-dimensional image, when necessary we use 3D CT to<br>additionally check the three-dimensional relationship.<br>For this patient, we judged that the relationship between the lower right wisdom tooth and the mandibular canal needed to be checked<br>in more detail on the panoramic X-ray, so we performed a CT scan.<\/p>\n\n\n\n<figure class=\"wp-block-gallery has-nested-images columns-2 wp-block-gallery-1 is-layout-flex wp-block-gallery-is-layout-flex\">\n<figure

class=\"has-text-align-center wp-block-paragraph\">On the 3D CT, we checked the positional relationship between the root of the wisdom tooth and the mandibular canal from several directions.<br>The purpose of this examination is not simply to check a single number for how many mm away the nerve is.<br>We use it to check the shape and direction of the wisdom tooth root and its three-dimensional relationship with the surrounding alveolar bone and the mandibular canal, and to plan the extraction method.<br>When the root of the wisdom tooth is close to the inferior alveolar nerve, the possibility of nerve damage<br>during extraction must be considered.<br>If the nerve is affected, reduced sensation or abnormal sensation may occur in areas such as the lower lip or chin,<br>and although most cases recover, in rare cases the symptoms may<br>persist for a long time, so a sufficient explanation to the patient before extraction is necessary.<\/p>\n\n\n\n<div

class=\"has-text-align-center wp-block-paragraph\">The extraction method varies depending on the position of the wisdom tooth.<br>For a wisdom tooth that is partly or completely covered by gum and bone, it may be necessary to make an incision in the gum within the necessary range<br>and expose the wisdom tooth.<br>If the tooth is lying at an angle or is difficult to remove in one piece,<br>the wisdom tooth may be divided into several parts and removed.<br>Depending on the case, part of the surrounding alveolar bone may also need to be removed.<br>What matters is not to simply judge that an extraction without any bone removal is a good extraction, but to perform the surgery while reducing damage to the surrounding tissue, considering the position and shape of the wisdom tooth,<br>within the necessary range.<\/p>\n\n\n\n<p class=\"has-text-align-center wp-block-paragraph\">For this patient as well, we performed the extraction with reference to the position of the wisdom tooth<br>and the surrounding structures confirmed on the CT.<\/p>\n\n\n\n<h2 id=\"sec-6\" class=\"wp-block-heading has-text-align-center\" style=\"color:#0b9b3f;font-size:1.15rem\">The wisdom tooth extraction is complete<\/h2>\n\n\n\n<p class=\"has-text-align-center wp-block-paragraph\">In the photo after extraction, you can see the area where the wisdom tooth used to be.<br>After a wisdom tooth is extracted, this space is not immediately filled with bone;<br>instead, a blood clot forms and the soft tissue and bone heal in sequence.<br>Right after extraction, it is important to be careful so that this blood clot is kept stable.<\/p>\n\n\n\n<h2 id=\"sec-7\" class=\"wp-block-heading has-text-align-center\" style=\"color:#0b9b3f;font-size:1.15rem\">What to watch out for after wisdom tooth

After extraction, pain, swelling, bleeding, infection, and dry socket may occur, and in the case of lower wisdom teeth, sensory changes related to the inferior alveolar nerve or lingual nerve may rarely occur.
