Beware of Dangers Before and After Tooth Extractions Almost no one knows about tooth extractions, and it is rare for almost a person to go their entire life without having a tooth extracted. Fewer people are aware of the dangers that can be associated with tooth extractions. Tooth extraction involves anesthesia of the relevant local nerves, which mainly involve the trigeminal nerve. Normally with anesthesia, extractions are rarely accidental, but in some people extractions can cause very serious problems through a “trigeminal-cardiac” reflex, which can lead to sudden death! Patients with a history of heart disease, especially arrhythmia, and especially middle-aged and elderly patients, who are mentally fragile, need to be especially careful. The “trigeminal-cardiac” reflex described above is likely to cause premature contractions, ectopic tachycardia, and even severe ventricular tachycardia or ventricular fibrillation before and after the extraction procedure. For this group of patients, a thorough cardiovascular examination should be carried out before tooth extraction, and the cardiologist should wait until he thinks you are ready for tooth extraction. It is also advisable to arrange for a supervised extraction by a cardiovascular specialist to avoid accidents. The earliest mention of this problem is that trigeminal nerve surgery procedures are prone to the above mentioned abnormalities and for this reason all related surgeries have to be monitored.
