Root Canal Treatment
A procedure to save a severely infected or damaged tooth by removing the infected pulp.
Overview
Root canal treatment, also called endodontic therapy, is a dental procedure that removes infected or damaged tissue from inside a tooth. Despite its reputation, modern root canals are no more uncomfortable than getting a filling and can save your natural tooth.
Step-by-Step Process
Examination & X-Ray
15-20 minutesThe dentist examines your tooth and takes X-rays to see the shape of the root canals and determine if there is any infection in the surrounding bone.
Tips:
- Bring previous dental records if available
- Inform dentist of any medications you take
Local Anesthesia
5-10 minutesThe area around the tooth is numbed with local anesthesia. You may feel a small pinch, but the tooth and surrounding area will be completely numb during the procedure.
Tips:
- Let dentist know if you have anxiety
- Sedation options may be available
Rubber Dam Placement
2-3 minutesA small rubber sheet (dental dam) is placed around the tooth to keep it dry and free of saliva during the procedure.
Access Opening
5-10 minutesThe dentist creates a small opening in the crown of the tooth to access the pulp chamber and root canals.
Pulp Removal & Cleaning
30-45 minutesUsing special instruments, the infected or damaged pulp is removed. The root canals are then cleaned, shaped, and disinfected.
Tips:
- You may hear scraping sounds - this is normal
- Let dentist know if you feel any discomfort
Filling the Canals
15-20 minutesThe cleaned canals are filled with a rubber-like material called gutta-percha, then sealed with adhesive cement.
Temporary Filling
5-10 minutesA temporary filling is placed to close the opening. You will return for a permanent restoration (usually a crown).
Crown Placement (Follow-up)
1-2 hours (separate visit)In a separate appointment, a crown is placed over the tooth to protect it and restore full function.
Tips:
- Schedule crown appointment promptly
- Avoid chewing on tooth until crown is placed
📋Before Treatment
- Eat a normal meal before your appointment (you may not eat for several hours after)
- Take any prescribed antibiotics as directed
- Avoid alcohol for 24 hours before
- Get a good night's sleep
- Arrange transportation if receiving sedation
✅After Care
- Avoid chewing on the treated side until numbness wears off
- Take prescribed pain medication as directed
- Over-the-counter ibuprofen usually manages any discomfort
- Some sensitivity is normal for a few days
- Avoid hard or crunchy foods until crown is placed
- Continue normal brushing and flossing
- Return promptly for crown placement
👍Benefits
- Saves your natural tooth

- Prevents infection from spreading
- Maintains natural appearance
- Normal chewing function preserved
- Cost-effective compared to extraction and replacement
⚠️Potential Risks
- Temporary sensitivity or mild discomfort
- Infection (rare with proper treatment)
- Cracked root (uncommon)
- Incomplete removal of infected tissue (may require retreatment)
- Instrument breakage inside canal (rare)
Frequently Asked Questions
Is a root canal painful?
Modern root canals are no more painful than getting a filling. Local anesthesia completely numbs the area. Most patients report feeling pressure but no pain during the procedure.
How long does a root canal take?
A typical root canal takes 30-90 minutes. Front teeth with one canal are faster, while molars with multiple canals take longer. Some complex cases may require two visits.
Do I need a crown after root canal?
Yes, in most cases. A crown protects the tooth from fracturing and restores full chewing function. Front teeth sometimes only need a filling, but back teeth almost always need crowns.
