The best time for tooth extraction is in the afternoon: When it comes to tooth extraction, although many people will frown, most of them just feel some pain and will pass after enduring it. However, tooth extraction is actually a surgery, and it is not uncommon for patients to die accidentally after tooth extraction for various reasons in clinical practice. Therefore, although the process of tooth extraction is “minor”, some details before and after the extraction are “major” and need the attention and caution of the extractor. Tooth extraction is not just a matter of pulling teeth whenever and wherever you want, but must pay attention to “timing, location and harmony”: since the human body’s pain response is more sensitive in the morning than in the afternoon, tooth extraction should be arranged in the afternoon as much as possible. It is also necessary to have sufficient energy and strength before tooth extraction, such as when you have just finished a late night or a long trip, or after overexertion, you should avoid tooth extraction. Special attention should be paid to the following cases, otherwise there may be serious consequences: extraction should be postponed during women’s menstruation and pregnancy to avoid hemorrhage during menstruation or inducing premature birth or even miscarriage during pregnancy; patients with previous history of drug allergy should give detailed explanation to the doctor during extraction to avoid allergic reaction to anesthetic drugs. In addition, don’t pull when you have a cold, and patients suffering from hyperthyroidism, hepatitis, nephritis, blood disease or diabetes, especially elderly patients, should undergo necessary examination and treatment and must be pulled only after their condition is under control. The end of tooth extraction does not mean the end of the problems in the mouth. Since bleeding and infection are most likely to occur after tooth extraction, there are many details to understand and master: first of all, there is something to be said for gently biting a cotton ball or gauze ball to stop bleeding. If you bite too hard, it will hurt a lot; if you bite too lightly or for too short a time, it will not help to stop the bleeding; if you bite too long, the saliva will soak through the cotton gauze and it will be easily infected. Therefore, it is best to bite lightly for 30D40 minutes before spitting out. Secondly, tooth extraction is a traumatic surgery, so you should pay attention to rest after surgery, talk less, do not do strenuous exercise or heavy physical labor, do not smoke or drink alcohol to avoid aggravating the pain and prolonging the healing period of the wound. Again, you should not rinse your mouth or eat for 2 hours after tooth extraction, and do not lick the wound with your tongue or touch it with your fingers to avoid rebleeding or secondary infection. Finally, avoid brushing your teeth on the day of tooth extraction to prevent the coagulated wound from bleeding again, rinse your mouth with mild mouthwash or light salt water, and avoid eating foods that are too hot or too hard or spicy, and eat more vitamin-rich fruit juice or fruit puree to supplement nutrition and promote wound healing. It is normal to have slight pain and some pink blood or blood in the spitted saliva within 24 hours after tooth extraction, and you can take the right amount of anti-inflammatory and analgesic drugs under the guidance of the physician. However, it is worth noting that the pain and bleeding should be getting lighter and less. If there is still persistent bleeding or pain after a few days, or even obvious dizziness and panic and other uncomfortable symptoms, you should immediately follow up with the hospital to identify the cause and deal with it promptly.
