Few procedures have a worse reputation than the root canal. Most of that reputation is decades out of date. This guide walks through what an endodontic visit actually feels like in 2025, the most common myths, and how to know if you need one.
What a root canal actually does
Inside every tooth there is a small channel of soft tissue called the pulp. When it becomes infected or dies (deep decay, a crack, or trauma), the surrounding bone can become inflamed and the tooth often hurts.
A root canal cleans out the infected pulp, disinfects the inside of the tooth, and seals it. The visible tooth is then rebuilt, usually with a crown. The tooth stays in your mouth instead of being extracted.
The most common myths
"Root canals are painful." The procedure itself is done with strong local anesthetic. Most patients report it feels like a routine filling. The pain people remember is usually the infection, not the treatment.
"It is healthier to just pull the tooth."Saving a natural tooth is almost always preferred when possible. An empty space can shift other teeth, change your bite, and often costs more to replace than the root canal would have.
"Root canals cause systemic disease." This comes from decades-old research that has since been thoroughly re-examined. Modern dentistry and major dental organizations do not support that claim.
"They never last." A well-done root canal, followed by a crown and good home care, often lasts the rest of your life. Failures can happen, but they are not the rule.
Signs you might need one
Common reasons your dentist may recommend a root canal:
- Lingering sensitivity to hot or cold (more than 30 seconds)
- Spontaneous throbbing pain, especially at night
- Pain when biting on a specific tooth
- A small bump on the gum near a tooth (a sinus tract)
- A darkened tooth without obvious decay
- Deep decay or a crack seen on X-ray or CBCT
What the visit looks like
After numbing, a small opening is made in the top of the tooth. Fine instruments and irrigation clean the canals; CBCT (3D) imaging is used when anatomy is complex. The inside is sealed, and a temporary filling is placed.
Many cases are done in one visit; complex or retreatment cases may take two. The final crown is usually placed by your general dentist a few weeks later.
Endodontic visits at Dental Salon are at our Lincoln Park office with a dentist whose practice is focused on endodontics. Schaumburg patients can be seen at Lincoln Park for the root canal and return to Schaumburg for the final crown.
Frequently asked questions
How long does the appointment take?
Most root canals take 60 to 90 minutes. Complex cases (molars with extra canals, retreatments) can run longer and are sometimes split across two visits.
Will I be sore after?
Mild soreness for 24 to 72 hours is common, especially if the tooth was already inflamed. Over-the-counter pain relief is usually enough.
Why do I need a crown afterward?
A treated tooth is more brittle than a healthy one. A crown protects it from fracturing, which is the most common reason a root-canal-treated tooth is lost long-term.
Does insurance cover root canals?
Most PPO plans cover a portion. We verify benefits before treatment and offer financing for any balance. See our insurance page.
What if I need sedation?
Oral or IV sedation is available for anxious patients or longer cases.
