Wisdom teeth are usually any of the four third molars and appear between the ages of 17 and 25. They affect other teeth as they develop, becoming 'impacted' or coming in sideways. This causes pain and they need to be extracted. Sometimes cysts and tumors appear around the impaction site, especially in older patients and require surgical removal. Sometimes the wisdom tooth does not come out fully (partial eruption) and a portion of the gum remains covering the top surface. Debris and bacteria enter in-between, causing infection, bad breath and redness, pain in the site, which in extreme cases can extend to the jaws and the back of the neck.
Extraction becomes necessary to ease these symptoms. Wisdom teeth are extracted for two main reasons, either the teeth have already become impacted, or would result in problems that include food particles easily trapped in the jaw area behind wisdom tooth where regular brushing or flossing are ineffective and lead to infections, which could be frequent and cause medical danger. Signs of tooth infections after wisdom teeth extraction are many and the person must follow the instructions of the dental surgeons closely. Some of these are recounted below: In conclusion, wisdom teeth start coming out during the ages of 17 and 25 in most people and are positioned in the molar area, usually the four third molars on either side of the jaws. Complications arise when the upcoming tooth comes up sideway, 'impacting' the neighbouring tooth. Pain caused when this happens, necessitates extraction. In other cases, the tooth does not come through completely, causing a portion of the gum above the tooth to cover it.
Food trapped in-between leads to infection, pain, bad breath and redness, pain in the site, which in extreme cases can extend to the jaws and the back of the neck. Extraction becomes necessary to ease these symptoms. However, extraction of the wisdom teeth is not the always the easy way out. There are a number of attendant problems, which are the signs of tooth infection post extraction such as bleeding and oozing, dry socket, swelling and inadvertent nerve injury, which are described in some detail above.
