Why don't some dentists use anesthetic when doing root canal therapy?
Not to save money, of course. You must pay all the expenses for dental treatment. Why can't doctors be reluctant to part with it? It's just that some doctors try to use fewer anesthetics to protect your brain, because people who use more anesthetics will develop drug resistance, and it will be troublesome to use anesthetics in the future. Moreover, anesthetics are harmful to the brain, so you should fight less if you can. For example, when filling ordinary teeth, there is no need to use anesthetic. It's a little sour when drilling, so just bear it. Anesthetic is a controlled substance, and doctors will not prescribe it unless it is necessary for treatment, because everyone needs to sign it, and no one wants to take responsibility. Root canal therapy is a bit painful. If the doctor thinks it's just average, he won't prescribe anesthetic, but he will definitely prescribe anesthetic after wisdom teeth are pulled out. Since you survived without anesthesia, it shows that you are better than ordinary people, so what are you afraid of?
