How To Know If Wisdom Teeth Really Need To Be Removed

There is ongoing debate regarding the need to extract wisdom teeth. Numerous scientific publications have aimed to clarify when it is medically appropriate to extract wisdom teeth, while many non-surgeons and patients have argued that there are too many unnecessary extractions.we supply all kinds of polished tiles, A recent article in The New York Times again raised the question of the value of wisdom teeth extraction. The author provided no clinical information about her daughter's case but used it as an example of yet another patient who was misled into thinking that "her wisdom teeth had to come out, A.S.A.P." (1) This kind of criticism is nothing new to the medical community: Last year, President Obama suggested that otolaryngologists frivolously remove young people's tonsils. Obama quickly retracted his statement,Replacement China Porcelain tile and bulbs for Canada and Worldwide. but when critics perpetuate these unfortunate stereotypes, it makes the job of responsible and fair doctors that much harder.

The information below is intended to help patients evaluate the indications for wisdom teeth extraction. Much of this information is based on the "White Paper on Third Molar Data" published by the American Association of Oral and Maxillofacial Surgeons, which reviewed the current literature published on wisdom teeth and their removal.

Several factors need to be considered when evaluating wisdom teeth: The health of the second molar, the presence of gum disease, the age of the patient and the risk of dental crowding. To minimize the possibility of negative outcomes, the use of cone beam imaging will also be discussed.

Adults have 32 teeth in their mouth, which includes the second molars, located immediately in front of the wisdom teeth. When evaluating wisdom teeth,we supply all kinds of polished tiles, it is important to evaluate the health of the second molars to make sure they are not compromised by the position of the wisdom teeth. Wisdom teeth can grow in a variety of positions: Sometimes they erupt straight up like the rest of the teeth, but other times they will grow sideways or toward the second molars, encroaching on their space. Research has shown that the ligament surrounding the second molars and its roots can be negatively affected by wisdom teeth, especially as one gets older.

When these conditions are already present, they improve with time after removal of the wisdom teeth, but it is important to note that the outcome correlates with the age of the patient and the level of plaque present in the mouth. For example, a teenager with impacted wisdom teeth and plaque buildup around the second molars will probably do well after the wisdom teeth are removed, but an older patient in in his 30s may have a bone or gum defect behind the second molars after the wisdom teeth are extracted.

Another factor to evaluate is the pocket depth measurement behind the second molars. A pocket depth of 5mm or more can compromise the second molars. These pocket depths have been shown to increase over time, and bacteria associated with gum disease have been found in these gum pockets, suggesting that impacted wisdom teeth can have a detrimental effect on the health of the gums. Notably, the bacteria count around the molars has been shown to decrease after removal of wisdom teeth.

After extraction of wisdom teeth, some surgeons have advocated bone grafting to improve the outcome of the second molar. This does appear to offer an advantage in preventing a defect behind the second molar, but only in adults 26 years of age or older with a pre-existing attachment loss and an impacted and mal-positioned wisdom tooth that is severely compromising the second molar.The additions focus on key tag and magic cube combinations,

It is also important to note the effect of wisdom teeth on gum disease and inflammation,It's hard to beat the versatility of zentai suits on a production line. which has been linked to a negative systemic impact on pregnancy outcomes in women with asymptomatic retained wisdom teeth. (9) In short, the presence of wisdom teeth tends to cause inflammation, which can negatively impact physical health, including pregnancy outcomes.
