Blood pressure may rise after tooth extraction, mainly due to emotional stress during extraction, or the patient’s own high blood pressure symptoms, etc. During extraction, patients tend to feel nervous and uneasy. During the extraction process, patients tend to feel nervous and uneasy, and tooth extraction also tends to cause localized bleeding and pain, which may trigger an increase in blood pressure, but as the pain slows down and the bleeding stops, the rising blood pressure will drop and gradually return to a stable level. For this type of elevated blood pressure after tooth extraction, there is no need to worry too much, and you can keep abreast of the blood pressure situation by measuring the blood pressure at regular intervals. If the patient has high blood pressure, after the anesthesia medicine injected during tooth extraction subsides, local pain appears, which will easily trigger the blood pressure to rise, and the rise in blood pressure will easily cause the wound of tooth extraction to bleed again, the patient can understand his own blood pressure status through blood pressure measurement, and if necessary, he can take antihypertensive medicines under the guidance of the physician, such as amlodipine, metoprolol and so on to regulate the blood pressure. After tooth extraction, patients can observe their own blood pressure level through blood pressure measurement. If the blood pressure fluctuates greatly and lasts for a long period of time, they should consult a doctor in time for examination to clarify the cause of the disease and carry out targeted treatment as soon as possible.
