Endodontic care
Root canal therapy: saving infected teeth & relieving pain
A root canal eliminates deep, painful infection from inside your tooth while preserving your natural tooth structure. Backed by Dr. Farid Gogani's cariology research background, our mobile dental practice provides emergency endodontic care and definitive restorative treatment across Greater Sacramento and Placer County.

What is root canal therapy?
Root canal therapy (endodontic treatment) is a dental procedure designed to eliminate infection from inside a diseased tooth and protect the tooth from future microbial invasion. Rather than causing pain, root canal treatment is the most reliable clinical method to stop severe tooth pain caused by an inflamed or infected dental pulp.
Care is led by Dr. Farid Gogani, DDS, who conducted research with the department of cariology at the University of Gothenburg in Sweden before earning California dental licensure in 1999. His deep background in tooth decay progression and biological preservation informs every aspect of our endodontic and restorative care.
Signs of an infected or inflamed dental pulp
The dental pulp is the innermost living tissue of a tooth, containing blood vessels, nerves, and connective tissue. When bacteria reach the pulp chamber through deep decay, repeated dental procedures, or a hairline crack, acute inflammation (pulpitis) develops.
Common warning signs
- Lingering thermal sensitivity: Sharp pain from hot coffee or cold water that lingers for 15 to 30 seconds or longer after the temperature source is gone.
- Spontaneous throbbing ache: Severe toothache that strikes without warning, pulses rhythmically, or wakes you from sleep at night.
- Biting tenderness: Sharp pain or ache when chewing food or tapping on the tooth.
- Gum pimple or fistula: A small bump on the gum tissue near the tooth root that may weep fluid and leave an unpleasant taste.
- Tooth discoloration: A tooth that gradually turns gray or dark yellow due to internal pulp necrosis.
- Facial or jaw swelling: Swelling of the cheek or jawline indicating that infection has breached the root tip into surrounding bone.
Inside the tooth: how infection develops
A healthy tooth consists of three distinct layers:
The hard, mineralized outer shell that shields the tooth from chewing forces and acid wear.
The softer, microscopic tube-filled layer beneath enamel that cushions the pulp and transmits sensations.
The central hollow space containing the nerves, arterioles, and living tissues extending down to the root tip.
When untreated bacterial decay penetrates through enamel and dentin, oral bacteria enter the sterile pulp chamber. The body mounts an inflammatory immune response, but because the pulp is encased in rigid hard tissue, pressure builds rapidly inside the tooth with nowhere to expand. This hydrostatic pressure creates the intense, throbbing toothache typical of acute pulpitis.
The step-by-step root canal procedure
Modern endodontic treatment is straightforward and comfortable. Thanks to modern local anesthetics and precise rotary instrumentation, the sensation is very similar to receiving a standard dental filling.
-
Step 1
Diagnosis & digital imaging
We take digital radiographs to visualize root length, canal curvature, and any periapical bone lesions around the root tips.
-
Step 2
Targeted local anesthesia
The tooth and surrounding tissues are thoroughly numbed. The dentist verifies complete numbness before any treatment begins.
-
Step 3
Access & disinfection
A tiny opening is made in the chewing surface of the tooth. Using precision micro-instruments, the inflamed pulp is gently removed, and each root canal is shaped and disinfected with antibacterial irrigants.
-
Step 4
Biocompatible canal sealing
The sanitized root canals are filled and hermetically sealed with gutta-percha, a biocompatible natural rubber material that prevents bacteria from re-entering.
-
Step 5
Coronal restoration
A temporary or permanent filling seals the access cavity until a permanent protective crown can be placed.
Why back teeth require a dental crown
A tooth that has undergone root canal therapy is no longer vital; because its internal blood supply has been removed, the remaining dentin becomes more dehydrated and brittle over time. In addition, deep decay often removes significant portions of the tooth's structural walls.
For molars and premolars that withstand hundreds of pounds of biting pressure during daily chewing, placing a custom dental crown is crucial. The crown encircles the remaining tooth structure like a protective helmet, preventing vertical root fractures that could otherwise cause the loss of the tooth.

Saving your natural tooth vs extraction
Patients experiencing intense toothache often wonder whether it is easier to simply have the tooth pulled. Comparing both approaches clarifies why saving your natural tooth is almost always the preferred clinical choice:
| Factor | Root Canal Therapy | Tooth Extraction |
|---|---|---|
| Natural tooth preserved? | Yes. Your natural tooth root and periodontal ligament stay intact. | No. The tooth is permanently removed, leaving an open bone socket. |
| Chewing efficiency | Maintains normal, natural chewing force and proprioception. | Chewing ability is reduced until an implant or bridge is placed. |
| Adjacent teeth stability | Neighboring teeth remain firmly in their correct positions. | Adjacent and opposing teeth tend to drift into the empty space over time. |
| Overall treatment timeline | Usually completed in 1 to 2 visits including the crown restoration. | Requires months of bone healing if planning a dental implant. |
Recovery and post-treatment aftercare
It is normal for the treated tooth to feel slightly tender to bite on for two to three days following root canal therapy as the surrounding tissues settle down. Follow these simple recommendations to ensure rapid healing:
- Chew on the opposite side: Avoid chewing hard, sticky or crunchy foods on the treated tooth until your permanent crown has been fitted.
- Take recommended analgesics: Mild over-the-counter pain relievers such as ibuprofen or acetaminophen typically manage post-treatment soreness effectively.
- Maintain gentle oral hygiene: Continue brushing and flossing around the tooth gently to keep the area free of plaque.
- Watch for unusual symptoms: If you experience severe swelling, a rash, or pain that persists beyond five days, call our team immediately.

Questions patients ask
Root canal therapy questions
Still have a question? Call 1-855-759-0782 and talk it through with our team.
Why choose a root canal instead of pulling the tooth?
Keeping your natural tooth preserves your normal chewing ability, natural bite alignment and jawbone volume. While extracting a tooth may seem simpler initially, replacing it with an implant or bridge usually requires more time and expense than saving it with root canal therapy.
What are the warning signs that I might need a root canal?
Common symptoms include severe, persistent toothache, sensitivity to hot and cold that lingers for seconds or minutes after the source is removed, pain when chewing, a darkened tooth, and a pimple or bump on the gums that may drain bad-tasting fluid.
Does a root canal relieve the pain?
Yes. A root canal is designed to relieve severe tooth pain, not cause it. The procedure removes the inflamed, infected nerve tissue inside the tooth under local anesthesia. Most patients feel immediate relief from the throbbing ache once the infection is cleaned out.
Do I always need a crown after a root canal?
For back teeth (molars and premolars) that endure heavy chewing pressure, a dental crown is strongly recommended. Removing the tooth's blood supply leaves it more brittle, and a crown protects the tooth from cracking or splitting.
How long does a root canal procedure take?
Most root canal treatments can be completed in a single visit of about 60 to 90 minutes. In cases of severe infection, a medicated dressing may be placed inside the tooth for a short period before the canals are permanently sealed.
Can a root canal fail?
Root canals have a high success rate, often exceeding 95%. However, deep hidden canals, curved roots, or new decay around an old restoration can sometimes lead to reinfection. Dr. Gogani's research background in cariology and restorative techniques ensures thorough disinfection and sealing.
