The dental nerve is also called pulp. What is it? It is a complex anatomical system consisting of many vessels under the tooth enamel. Just the nerve provides sensitivity of the tooth – the tooth reacts to temperature changes, mechanical effects, etc.
When there is a severe toothache that can not be tolerated, the patient turns to the dentist, and the latter often makes a verdict – you need to remove the nerve. After removing the nerve, the tooth loses sensitivity at all. Simply put, he becomes dead because his blood supply is completely cut off.
