In clinical practice, we often encounter patients who need to have a tooth extracted immediately for various reasons, but are reluctant to do so or have to have a tooth extracted that should not have been extracted because of a special fear of extraction and various misconceptions and prejudices about it. What are these misconceptions and prejudices that we often encounter? 1. Extracting a tooth will loosen a lot of teeth. After tooth extraction (except wisdom teeth), dental implants should be placed within six months. If you do not make dentures for more than six months, the adjacent teeth will tilt toward the missing gap and the opposite teeth will elongate. People think that tooth extraction will lead to the loosening of surrounding teeth, the reason, lies in the lack of timely restoration of missing teeth after tooth extraction or the use of inappropriate restoration methods, resulting in the surrounding teeth are not conducive to cleaning or the formation of hygienic dead space, leading to the occurrence and development of periodontitis, making it loose. 2, the removal of wisdom teeth (is the third molar, commonly known as “root teeth”, “end teeth”, “wisdom teeth”) will make the front teeth backward, loosening. Generally speaking, our teeth keep moving forward throughout our lives, and the removal of wisdom teeth located at the very end of the tooth row will not loosen the front teeth. 3. My teeth are not good, so I will wait for all of them to be extracted to set a full mouth. The more teeth that can be preserved in the mouth, even the roots (retaining a periodontal membrane intact residual root can maintain the physiological stimulation of the alveolar bone, prevent alveolar bone atrophy and delay aging), the less difficult it is to repair missing teeth, and the better the restoration results. The World Health Organization (WHO) proposed the “8020 plan” in 2008, that is, 20 real teeth that can chew normally should be retained at the age of 80. 4, extraction is very painful, let it fall off by itself. Generally speaking, nowadays, anesthesia can achieve a good analgesic effect throughout the whole process, and even the anesthetic itself can be basically painless, so you can feel at ease with the tooth extraction. The tooth that needs to be extracted will bring us a lot of potential dangers, which may lead to the inability to use the affected tooth due to pain, chewing on one side, walking on one leg, causing facial asymmetry, causing discomfort in the jaw joint, and even leading to the destruction of the joint in serious cases; so that the other teeth on the affected side are also damaged (chewing has a self-cleaning effect, and the side that is not used often has poor oral hygiene). If the alveolar bone of the affected tooth is absorbed more than 2/3 of the root length is not extracted in time, the alveolar bone will be further absorbed and lost, which is not conducive to later restoration. 5, tooth pain, loose to be extracted, once and for all. The pain and looseness of teeth can be caused by many factors, which can generally be preserved by the treatment of the right cause of dental, periodontal and even inlay. Extraction is only one of the ways to treat a diseased tooth, unless the root of the tooth is rotten or the affected tooth has more than 2/3 of the root length of the alveolar bone resorption. Tooth extraction can cause a series of reactions, such as loss of chewing function, displacement of neighboring teeth, and aesthetic loss. 6. Tooth extraction is bad for the brain and makes people stupid. The teeth grow in the alveolar bone, which is far from the brain, and the dental nerve is also the fifth nerve to the end of the trigeminal nerve of the brain, so tooth extraction has no effect on the brain. 7. Do not pull out teeth at noon, otherwise there will be more than blood flow, and there will be a “bloodbath”. During the day, human blood pressure is high and low, and it is probably higher at noon. However, generally speaking, there is no need to worry about the bleeding as the damage caused by the extraction by an experienced doctor is minimal, and the bleeding can be stopped immediately even by a doctor. However, for some patients, there are advantages to picking the right time to have a tooth pulled. For example, dialysis patients must wait 6 hours after hemodialysis before tooth extraction because the anticoagulant used during dialysis can affect the hemostasis after extraction, so they must wait for the effect of the drug to wear off before extraction.
