If your dentist just said you need a root canal, the first thing that probably ran through your head was not relief. Most people picture the procedure as something to dread. This reputation has been around for decades and it is almost entirely outdated. At ABQ Dental Care in Albuquerque, root canal therapy is designed to relieve pain, not create it, and most patients are surprised by how manageable the experience feels. Understanding what actually happens during treatment can go a long way toward easing anxiety before your visit.
The actual experience for most patients today is far closer to getting a filling than anything resembling the horror stories. The tooth gets numb, the dentist works, you feel pressure. That is usually about it.
People who tend to need root canals most often are adults in their 30s through 60s dealing with deep decay, a cracked tooth that was ignored too long, or an abscess that has been quietly building. Men and women need them at similar rates. The American Association of Endodontists reports that over 41,000 root canals are performed in the United States every single day. Most of those patients walk out the same afternoon and go about their day.
At ABQ Dental Care in Albuquerque, NM, the patients who come in most nervous are usually the ones who leave most surprised. They braced for something awful and felt almost nothing. In this blog, we will discuss the truth about root canal when it comes to pain and what to expect during the procedure.
Why Root Canals Have Such a Bad Reputation
The bad reputation comes from a different era. Before effective anesthetic protocols, before rotary endodontic instruments, before digital X-rays that let a dentist map the anatomy of a root canal precisely before touching it, the procedure was harder on patients. That era is gone.
What actually hurts is the infection. The throbbing, pressure-like ache keeping you up at night is caused by bacterial infection inside the pulp chamber, not by anything the dentist is about to do. Root canal treatment removes that source. Generally, patients feel genuine relief within a day or two.
“The patients who are most surprised are the ones who came in absolutely terrified. Once we get the anesthesia working properly, the procedure is quiet. They expected the worst and felt almost nothing.” — Dr. Rohan Toor DDS
What Do You Actually Feel During a Root Canal?
The injection of local anesthetic is the sharpest part of the whole appointment. It is brief. Once lidocaine or articaine takes effect, the pulp tissue and surrounding structures are numb. There should be no sharp pain after that point.
What remains is pressure. Endodontic files moving through the canals, irrigation solution flushing the chamber, the rubber dam clamp sitting against the gumline. None of it should hurt. If anything feels sharper than pressure at any point, additional anesthetic can be delivered immediately. You do not have to sit through discomfort.
What Happens Step by Step Inside the Tooth?
The dentist places a rubber dam around the tooth first. It is a thin sheet that isolates the tooth, keeps saliva out of the field, and prevents any bacteria from re-entering the canal during treatment. Then a small opening is made through the crown of the tooth to reach the pulp chamber underneath.
Flexible endodontic files remove the infected or necrotic pulp tissue and shape the canals. Sodium hypochlorite irrigation flushes out residual bacteria. Once the canals are clean and shaped, they get filled with gutta-percha, a biocompatible rubber-like material that permanently seals the space. A temporary or permanent restoration closes the access point.
A single-rooted front tooth usually takes about 60 minutes. A lower molar with three or four canals can run longer. Some cases need two appointments, particularly when there is significant infection that needs time to settle before the canals are sealed.
Why Lower Molars Are a Different Challenge
Mandibular molars are legitimately harder to anesthetize fully, especially when the pulp is still vital and inflamed. The inferior alveolar nerve block, the standard injection for lower back teeth, does not always achieve complete numbness in teeth with acute irreversible pulpitis. In those cases, supplemental intraligamentary or intraosseous injections are often needed. That is a known clinical challenge, not a sign anything is going wrong. A dentist experienced in endodontics knows how to manage it.
How Does Sedation Help During a Root Canal?
Local anesthesia handles physical sensation. Sedation handles the anxiety, the hyperawareness, the difficulty sitting still for an hour when your nervous system is already in overdrive. They serve different purposes and can be used together.
Nitrous Oxide for Mild Anxiety
Nitrous oxide comes through a small nasal mask worn during the appointment. It produces a calm, slightly detached feeling within a few minutes. You stay conscious, you can answer questions, and the effect clears quickly once the mask comes off. Most patients can drive themselves home. This works well for people with mild to moderate anxiety who mostly just need the edge taken off.
Oral Conscious Sedation for Moderate Anxiety
A prescription sedative, usually a benzodiazepine, is taken about an hour before the appointment. You will be drowsy and relaxed, and many patients remember very little of the procedure afterward. You need a driver. This option tends to work well for patients who tense up significantly in the dental chair or have a strong gag reflex that complicates treatment.
IV Sedation for Significant Dental Phobia
For patients with significant dental phobia or more complex treatment needs, intravenous sedation delivers medication directly into the bloodstream. The effect is faster and the level can be adjusted throughout the procedure. You will need someone to drive you home and should plan to rest for the rest of the day. It is not something everyone needs, but for patients who genuinely cannot get through dental treatment any other way, it makes a real difference.
| Sedation Type | How Aware You Are | Recovery | Works Best For |
|---|---|---|---|
| Nitrous oxide | Fully awake, relaxed | Minutes | Mild anxiety |
| Oral sedation | Drowsy, limited recall | Several hours | Moderate anxiety |
| IV sedation | Deep relaxation | Rest day needed | Severe phobia or complex cases |
What Should You Expect After the Procedure?
Expect soreness for a few days. The periapical tissue around the root was inflamed before treatment and takes time to quiet down. Ibuprofen or acetaminophen manages this for most people. A 2025 study of 162 patients found that post-treatment discomfort peaks in the first 24 to 48 hours and drops sharply by day seven. Prescription pain medication is rarely necessary, since it’s expected to improve over time.
Do not chew on the treated tooth until a crown or permanent restoration is placed. The access opening left in the tooth after treatment weakens the structure. Biting hard food on an unprotected root canal tooth can fracture it, which creates a much bigger problem than the one you just solved.
Call the office if you develop significant swelling, a fever, or pain that gets clearly worse after day three instead of better. Those symptoms suggest the infection has not fully resolved and need to be evaluated promptly.

Tooth Pain in Albuquerque That Has Gone on Too Long?
If a tooth has been hurting for days, that infection is not going to resolve on its own. Waiting usually leads to more damage, more extensive treatment, and more time in the chair rather than less.

Rohan Toor DDS and the team will tell you straight what your tooth needs, what the procedure will feel like, and what your sedation options are if anxiety is part of the picture.
