Root canals aren't what they used to be.
They're far gentler than their reputation.

The reputation of root canals is 30 years out of date. With modern techniques and anesthesia, most patients say the procedure is "much easier than a filling" — because the anesthetic deadens the nerve that was causing all the pain in the first place. In 1–2 visits, we save the tooth and stop the pain.

What actually
happens.

A root canal treats infection inside the tooth's pulp chamber. Despite the reputation, the actual procedure is straightforward. Here's the walk-through.

1
Diagnosis · 15 min

An X-ray and a cold test tell us if the nerve is dying or already dead. If you're in a lot of pain, we'll often do a "pulpotomy" first — a quick procedure that relieves the pressure and gives you immediate pain relief.

2
Full anesthesia · 5 min

We thoroughly numb the tooth and surrounding area. This is the critical step — once the nerve is numb, you feel nothing. If there's any sensitivity, we add more anesthetic until it's completely gone.

3
Access the nerve · 10 min

A small opening is made in the top of the tooth to reach the pulp chamber. This is where the infected or dying tissue is.

4
Clean the canals · 30-45 min

Using tiny flexible files, we remove the infected tissue, clean out the canals, and shape them for the filling. The tooth is rinsed with an antimicrobial solution.

5
Fill & seal · 15 min

The cleaned canals are filled with a biocompatible rubber-like material called gutta-percha, then sealed to prevent re-infection.

6
Temporary filling & plan for crown

A temporary filling goes on top. Most back-tooth root canals need a crown within a few weeks to prevent the tooth from cracking. We'll schedule that during your follow-up.

When a root canal is
the right call.

Symptom 01

Severe, lingering pain

If a tooth throbs at night, keeps you awake, or hurts for minutes after hot/cold exposure, the nerve is likely dying. Root canal typically needed.

Symptom 02

A pimple on the gum

A small bump on the gum above a tooth (called a "fistula") means infection has broken through the bone and is trying to drain. Classic sign of a root canal need.

Symptom 03

Dark discoloration

A single tooth turning gray or dark yellow — especially a front tooth after trauma years ago — means the nerve has died. Root canal plus internal bleaching can restore it.

Symptom 04

Pain when biting

If biting down on a specific tooth produces a sharp pain that doesn't go away, the nerve is likely inflamed or infected. Don't ignore this.

Symptom 05

Swelling or tenderness

Swelling in the gum or jaw near a tooth — especially if it comes and goes — means infection is present. Antibiotics may calm it temporarily, but the tooth itself needs treatment.

The alternative

The only other option is extraction.

If you don't do the root canal, the tooth has to come out. Once extracted, you'll need an implant ($4,000+) or a bridge ($3,000+) to replace it — far more expensive and invasive than the root canal itself. Saving your natural tooth is almost always the better call.

Questions
we hear often.

Does a root canal really not hurt?
Once the area is numb you typically feel pressure, not sharpness. The pain patients associate with "root canals" is actually the pain they had before the procedure, from the dying nerve. The root canal ends that pain. Most patients leave saying "that was much easier than I expected."
How long will the tooth last after a root canal?
A properly treated root canal plus a crown can last a lifetime. The key is the crown — without it, the tooth becomes brittle and is likely to crack. Back teeth almost always need a crown after a root canal; front teeth sometimes don't.
Why do I need a crown on top?
A root canal removes the blood supply from inside the tooth. This makes the tooth drier and more prone to fracture under chewing forces. A crown reinforces what's left. For back teeth, this is standard care.
Can I just pull the tooth instead?
Yes, but replacing it will cost 3–5× more than the root canal. An implant is $4,000+. A bridge is $3,000+. A partial denture affects the teeth around it and wears out faster. If the tooth can be saved with a root canal, saving it is almost always the better call.
How much does it cost?
Root canals typically run $900–$1,600 depending on which tooth (back teeth have more canals and are more complex). Add $1,200–$1,800 for the follow-up crown. Most PPO insurance covers 50–80%.
How long is recovery?
Most patients go back to work the same day. Some tenderness for 2–3 days is normal. Any severe pain, swelling, or fever should be called in — sometimes a second visit is needed for stubborn infections, but this is uncommon.

fix itself.
