Wisdom teeth are the third molars at the back of the mouth. Modern people’s food is becoming more and more refined, and the chewing organs are also degenerating, making the jawbone less space to accommodate teeth, so most of the last erupted wisdom teeth are obstructed, manifesting as partial eruption, malpositioned eruption or completely buried obstruction. Therefore, wisdom teeth are typically occupying the tooth bed without chewing. If a wisdom tooth is decayed, even if time is spent on filling or even root canal treatment, most of them will end up with no chewing function. Therefore, it is generally recommended to remove them to eliminate future problems. However, many people still have doubts before they are “examined and sent to the execution ground”: will wisdom teeth extraction cause the front teeth to loosen? Will wisdom tooth extraction make people dumber? Will the anesthetic injection be bad for health? Theoretically, there is a possibility that wisdom tooth extraction will loosen the second molar, but in practice, the doctor will try to avoid damaging the adjacent teeth, and the occurrence of such complications is not rare in clinical practice. There is no evidence that wisdom is affected by wisdom tooth extraction. As for anesthesia, it is generally safe for humans unless they are allergic to anesthetics or have systemic diseases such as heart disease. Wisdom tooth extraction is a very common treatment in oral and maxillofacial surgery clinics, so there is no reason to condone the “evil” wisdom tooth. Before sending wisdom teeth to the guillotine, it is important to remember to eat breakfast before extraction. Patients with high blood pressure should take antihypertensive medication to control their blood pressure and explain their history of hypertension to the doctor before extraction, and wait for the nurse to measure and confirm that their blood pressure is within the permissible range before extraction. Patients with a history of diabetes should take antibiotics to prevent infection before tooth extraction, and patients with blood sugar much higher than normal should not have their teeth extracted. Patients with other systemic diseases such as heart disease, blood disease, and female patients who are pregnant or menstruating should give a clear explanation to the doctor and wait until the doctor carefully excludes contraindications to tooth extraction before extracting teeth. After wisdom tooth extraction, you should bite the cotton ball tightly for half an hour to stop the bleeding, and you should not eat too hot and hard food or perform strenuous exercise after tooth extraction, and take antibiotics as prescribed by the doctor. I believe that without the endless “life-threatening” toothache brought by wisdom tooth pericoronitis, you will be able to smile more brightly and wisely with health and confidence!
