Knowledge about Wisdom Teeth
What are the dangers of wisdom teeth?Impacted wisdom teeth, that is, wisdom teeth that can only partially erupt or cannot erupt at all, may cause a series of clinical hazards, among which the common hazards are:1. Recurrent pericoronitisWisdom tooth pericoronitis is the most common hazard, mainly due to the formation of “blind pockets” between the soft tissue around the wisdom tooth crown and the tooth, causing the accumulation of food and bacteria.Patients with wisdom tooth pericoronitis usually have some systemic symptoms such as local swelling, pain, pus overflow and even fever.Wisdom tooth pericoronitis can be plain and ordinary and can be cured by anti-inflammatory treatment, but it can also be very dangerous. If not actively treated, wisdom tooth pericoronitis can lead to infection of the maxillofacial space.Tips: It should be noted that severe wisdom teeth can cause a high probability of interstitial infection, and may even cause serious complications such as sepsis and septicemia, endangering the patient’s life. 2. Damage to adjacent teethImpacted wisdom teeth, such as wisdom teeth that grow forward, will form an open gap with adjacent teeth, which is easy to accumulate food residues and is not easy to clean. Over time, it can lead to caries of adjacent teeth and even lead to pulpitis. Or the root or distal bone resorption of adjacent teeth due to compression. 3. Temporomandibular joint disorderBecause impacted wisdom teeth cannot establish a normal occlusal relationship with the opposing teeth, over time it can cause symptoms such as temporomandibular joint snapping, mouth opening pain, and night bruxism. 4. Other special circumstancesFor example, impacted wisdom teeth may compress the nerves during the growth process and become the focus of some neuralgia. Or the impacted wisdom teeth of cancer patients were not extracted before radiotherapy, and if infection occurs later, it may lead to radiation-induced jaw osteomyelitis or even osteonecrosis. When do wisdom teeth need to be removed?Impacted wisdom teeth, or symptomatic wisdom teeth, should be extracted as early as possible.It is usually recommended to extract wisdom teeth before the age of 25, because before this age, the wisdom teeth have just erupted, and the roots are usually not fully stabilized, and the effect on the inferior alveolar canal is also small, and the resistance to the extraction of wisdom teeth at this time is relatively small.In addition, since most wisdom teeth have almost no masticatory function, and in view of the possible harm it may cause, preventive extraction of asymptomatic wisdom teeth can also be considered.To sum up, after knowing so much basic knowledge about wisdom teeth, what should you pay attention to in the process of wisdom teeth extraction?
