What are the dangers of extracting a tooth's nerve?

If your condition is so serious that the dental nerve needs to be extracted, then the patient must pay attention to his eating and living habits after the extraction, so that the harm to his body after the extraction of the dental nerve can be reduced. If you already have a serious cardiovascular disease, it is best not to have the tooth extracted easily, as this will cause unnecessary problems.

(1) Those with severe cardiovascular disease and hypertension above 180/100 mmHg. Generally, patients with heart disease can have their teeth extracted as long as they do not show signs of heart failure (such as palpitations and shortness of breath during slight activities or lying down). However, the following should be done during tooth extraction: Do not add adrenaline to the anesthetic to avoid tachycardia and heart failure; Anesthesia should be complete and movements should be gentle to minimize adverse stimulation, bleeding or injury; Anti-infection prevention treatment should be given before and after tooth extraction, because heart disease patients have reduced resistance and are more susceptible to infection than normal people.

(2) Bleeding diseases: Patients with hemophilia and idiopathic thrombocytopenic purpura have impaired blood coagulation and are therefore prone to bleeding. Bleeding after tooth extraction is difficult to stop and may cause heavy bleeding and be life-threatening. For leukemia patients, who are extremely susceptible to infection, the wound after tooth extraction can become a focus of infection, leading to serious systemic infection that is difficult to control. Therefore, these patients should receive conservative treatment when suffering from dental diseases, and tooth extraction is contraindicated.

(3) Menstruation, pregnancy, and lactation: Women should avoid tooth extraction during menstruation in principle, because compensatory bleeding may occur in the alveolar cavity during menstruation. However, extracting loose teeth during menstruation will not have much impact on the patient. Some "deep-rooted" teeth, such as impacted teeth or impacted teeth, should be removed after menstruation. Data shows that it is most appropriate for women to have their teeth extracted around the 10th day of the menstrual cycle. At this time, the wound heals faster and bacterial infection is less likely to occur.

Some people believe that teeth should not be extracted during pregnancy because it may cause miscarriage. However, a large number of clinical practices have shown that tooth extraction during the 3rd to 7th month of pregnancy is relatively safe and has no adverse effects on pregnancy. When extracting teeth during this period, the following points should be noted: ① Inject 10 mg of progesterone intramuscularly the day before and on the day of tooth extraction. ② Do not add epinephrine to the tooth extraction anesthetic. ③The anesthesia must be complete and the analgesic effect must be good. Tooth extraction is prohibited during pregnancy for patients with a history of habitual miscarriage or habitual premature birth. It is completely possible to have teeth extracted during breastfeeding. Some people say that having teeth extracted during this period will interrupt or reduce milk secretion.

This statement is unscientific. Clinical practice shows that it has no effect on milk secretion. But do not take antibiotics, as the drugs and their metabolites can pass through breast milk and may affect the baby. While taking birth control pills, they can increase the decomposition of fibrin in the body, making it impossible for the wound to form a good blood clot, making it easy for bacteria to take advantage of the opportunity to enter and cause infection, affecting wound healing.
