Should wisdom teeth erupt at 90 degrees, should they be extracted?

Wisdom tooth extraction is a controversial topic among dentists, other healthcare professionals, even third parties such as insurance companies, social policy makers, the community .
Follow-up management of wisdom teeth often revolves around identifying the presence of obvious symptoms or disease caused by wisdom teeth. However, as in many other diseases, such as diabetes and cardiovascular disease, the absence of symptoms in wisdom teeth (also called asymptomatic wisdom teeth) does not always reflect true absence of disease.
During the initial visit, the clinician can determine the presence or absence of symptoms by taking a thorough history from the patient. Many patients report that they do not experience any symptoms. Other patients complain of limited mouth opening (trismus) or periodic swelling and pain in the wisdom tooth area, or they have experienced a foul odor in the mouth. The dentist will perform a physical examination and then examine radiographs to determine whether the presence or absence of disease corresponds to the symptoms experienced by the patient.

If the wisdom tooth cannot be seen, the dentist will perform a periodontal exploration to determine if the tooth is communicating with the oral cavity. By probing behind the 7th molar, the dentist can contact and determine that there is an erupting wisdom tooth. This finding suggests the presence of chronic inflammation or the risk of provoking inflammation in the patient.

Misaligned wisdom teeth are recommended to be extracted in the following cases:
First: Causes gum problems. Wisdom teeth that are impacted implicitly compress other teeth and cause pain and swelling, especially when they have only partially erupted (push themselves up through the jawbone and gum tissue into the mouth). Partially erupted (semi-implanted) teeth can lead to infection, cyst formation, or swelling in the gum tissue or jawbone. These are serious problems that negatively affect your overall health.
Second: The growth of wisdom teeth can cause damage to neighboring teeth. The pockets around the wisdom teeth are underground, creating places where bacteria, food, and tartar are deposited. Cavities at the roots are easy to form in these cases. If the decay develops widely at the root of the adjacent tooth (teeth 7), it may be necessary to extract both wisdom teeth and teeth 7, so chewing will be greatly affected because tooth 7 is a functional molar. main chewing.
Third: The position of the teeth impedes jaw movement or affects chewing function in any way. Questions to ask are: do wisdom teeth rub against the soft tissues in your mouth? Does it make you bite your cheek? Is food getting stuck under the gum tissue around the wisdom teeth and causing swelling and/or pain in the gums while chewing? These are concerns that need to be addressed to keep you chewing food well and facilitate good digestion.

Fourth: If it is clear that the wisdom tooth will not erupt completely and is: (1) moving towards the adjacent root or (2) will never come into contact with the opposing tooth. Wisdom teeth move in the jawbone as they try to erupt. If they move in the direction of the adjacent root and put pressure on this tooth, it will cause root resorption. This will permanently damage the adjacent tooth and will require surgery on the affected root or extraction of the adjacent tooth. Also, if it becomes clear that the wisdom tooth will not come into contact with the opposing tooth, it is useless in terms of chewing function and the risks of keeping this wisdom tooth can often outweigh the benefits of keeping it. Conversely, if your wisdom tooth is growing in and isn't harmful in any way, it's best to leave it in place.
Fifth: Wisdom teeth cause pressure and displacement of the front teeth, which can affect orthodontic results. Indications to remove wisdom teeth for braces will usually be recommended by orthodontists depending on the stages in orthodontic treatment.
