Does a root canal hurt ?

No: your dentist will completely anesthetize (deaden) your tooth and then remove the pulp (red in this image). S/he will then sterilize the canal and seal it. You will then get a filling or crown and go on as if nothing ever happened. Despite the jokes root canal therapy (RCT) is a wonderful way of saving teeth that would otherwise have to be pulled.

RCT: Except in rare or unusual circumstances, a dentist can completely numb the tooth so that there is no pain during the procedure. It is not uncommon to have some mild soreness or discomfort following the procedure which is easily remedied by mild OTC pain medication. Often patients are amazed as they felt nothing during or after the procedure. The key is a competent dentist and early treatment.

Speak with dentist: The dentist will use a local to numb the area. Prior to this a topical is placed in the area to try to superficially numb the area to feel the needle less. If needed nitrous oxide can be utilized to calm any fears or the dentist can prescribe a low dose of valium to allay any anxiety. You will be fine.

Not usually: Not usually. Local anesthesia works well. You can as for an oral sedative to help with anxiety.

It Relieves Pain: A root canal is performed to relieve pain, not cause it. With modern techniques, a root canal can be performed 100% pain free. The majority of patients report near complete resolution of their pain immediately or shortly after receiving a root canal. Sometimes the tooth may be slightly sore after the procedure, but can be managed with over-the-counter pain medications.

Simply put no : Technology has progressed so much that root canal treatment could be done these days totally painlessly, once the proper anesthesia is given.

Dental procedure: As in any procedure medical and dental there is to be some pain expected but this can be managed. Your dentist may use a mucosal numbing agent before doing the dental block which makes things much easier to bear. After the procedure you will be sore but simple oral analgesia will usually do the trick. Topical agents, sat water gargles, ice (if tolerated), repeat dental blocks may help also.
