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?
Precautions for wisdom teeth extraction
What should you pay attention to when pulling out wisdom teeth?1. Tooth extraction is not recommended in the acute stage of wisdom tooth pericoronitis. In such cases, anti-inflammation and anti-infection treatment should be carried out first, followed by tooth extraction. 2. Tooth extraction before radiotherapy. Before radiotherapy for nasopharyngeal cancer or oral cancer, impacted wisdom teeth must be extracted to avoid potential hazards such as jaw osteomyelitis or osteonecrosis caused by wisdom teeth. 3. Patients with severe wisdom teeth or poor physical condition need to be hospitalized for surgical extraction. For example, if there are contraindications to tooth extraction, such as severe cardiovascular and cerebrovascular diseases, relevant examinations need to be completed, and teeth can only be extracted under the supervision of the operating room. 4. Precautions after tooth extraction. Generally speaking, the tooth extraction socket will initially heal in about a week, and the impact on eating will gradually become smaller. However, if there is obvious local pain after tooth extraction, even taking painkillers is ineffective, it is generally considered whether it is dry socket (dry socket is a bone wound infection caused by oral bacteria after tooth extraction, It usually occurs 3-4 days after tooth extraction, mainly manifested as persistent severe local pain, and involves ear and temporal pain, which cannot be relieved by taking general analgesics).In addition, if you experience symptoms of infection, significant swelling, or pain after tooth extraction, it is recommended to seek medical attention in time, and do not self-medicate. United States wisdom tooth extraction costThe United States can be said to be very simple and rude in the matter of wisdom teeth extraction. Their concept is that all wisdom teeth must be extracted, and four teeth can be extracted directly in one operation, and the sooner they are extracted, the better. Most Americans have all their wisdom teeth removed in high school and at the latest in college. Because American dentists believe that wisdom teeth have no chewing function, and their position is too close to the inside of the mouth, and most people can't brush their teeth. Wisdom teeth will cause a series of problems sooner or later, it is better to pull them out early to avoid future troubles.The cost of wisdom tooth extraction is still relatively high. In the United States, intravenous sedation is used to make you fall asleep completely without any feeling. This intravenous sedative injection costs 200-300 US dollars, and the effect is only 15 minutes. It takes half an hour to 45 minutes to extract 4 teeth at the fastest.Generally speaking, it is very necessary to purchase dental insurance. In addition to regular check-ups and cleanings, if there is a small problem with the teeth, it can also be treated in time.Although the above mentioned some problems that may be encountered in wisdom tooth extraction or precautions after tooth extraction, wisdom tooth extraction is generally relatively safe. After weighing the pros and cons, it is better to pull out the ones that should be pulled out as soon as possible.
