What Is Root Canal Treatment (Endodontic Therapy)?
Root canal treatment, also called endodontic therapy or endodontic treatment, is a dental procedure used to repair and save a badly decayed or infected tooth. The dental pulp is the chamber inside the tooth containing the nerve, blood vessels, and connective tissue. When the pulp becomes inflamed or infected, the bacteria multiply within the chamber and can cause an abscess if left untreated. Endodontic treatment removes the infected pulp, cleans and shapes the root canals using fine dental instruments and disinfecting solutions, and fills the canals with an inert material to prevent future bacterial entry. After the procedure, the tooth is sealed. Because the tooth loses its natural hydration once the nerve is removed, a crown is typically placed afterwards to protect it from fracture.
When Root Canal and Endodontic Treatment Is Needed
LA Dental Clinic provides endodontic treatment in Los Angeles for a range of clinical situations. Root canal therapy is indicated when the dental pulp is infected, inflamed, or dying, and cannot recover on its own.
Infected or Abscessed Tooth
When bacteria penetrate the pulp chamber, they multiply and cause infection that can spread to surrounding tissue. Endodontic treatment removes the infected pulp and clears the infection before it spreads further.
Severely Decayed Tooth
When decay is so advanced that the pulp is exposed or already affected, a filling is no longer sufficient. Endodontic therapy removes the damaged tissue and seals the tooth.
Cracked or Fractured Tooth
A crack that extends into the pulp allows bacteria to enter the tooth and infect it. Endodontic treatment addresses the infection and restores the structural integrity of the tooth.
Repeated Dental Procedures on One Tooth
Multiple fillings or procedures on the same tooth over time can irritate and eventually damage the pulp. This is one of the most common causes of endodontic treatment being needed.
Trauma to the Tooth
A blow to the face or mouth can damage the pulp even if the tooth does not appear visibly cracked. Endodontic evaluation after facial trauma is recommended where tooth pain or sensitivity develops in the weeks following.
Crown Placement After Treatment
After endodontic treatment, the tooth loses its natural hydration and becomes brittle. LA Dental Clinic typically recommends a crown to protect the treated tooth from fracture, especially for molars that bear the most biting force.
Signs You May Need Endodontic Treatment
Endodontic treatment is usually confirmed through clinical examination and X-rays by your dentist. However, several symptoms may indicate that the pulp of a tooth has become infected or inflamed and that root canal therapy is needed.
- Severe toothache when chewing or applying pressure to the tooth.
- Sharp pain or prolonged sensitivity to hot or cold temperatures that does not resolve quickly.
- Swelling or tenderness in the gum tissue near the affected tooth.
- Discoloration or darkening of the tooth.
- A persistent pimple or bump on the gum near the tooth, which may indicate an abscess draining.
-
Crowding or misalignment that is affecting bite function.
Having chipped a tooth, taken a blow to the face during a contact sport, or having had multiple repeat fillings on the same tooth are also situations that can indicate a need for endodontic assessment.
Root canal treatment at LA Dental Clinic is designed to be pain-free. Local anaesthetic is applied to fully numb the tooth before the procedure begins. Most patients report that the level of discomfort involved is similar to having a filling placed.
How Long Do Restorative Treatments Last?
With appropriate care, restorative treatments at LA Dental Clinic are built to last. The following are sourced directly from the practice's own information.
1
X-Rays and Diagnosis
Before any endodontic treatment begins, X-rays are taken to assess the severity of the damage to the tooth and to check the condition of the surrounding bone. This allows LA Dental Clinic to confirm the diagnosis, determine the extent of the infection, and plan the treatment accordingly.
2
Local Anaesthesia
A local anaesthetic is applied to freeze the tooth and the surrounding area. The tooth should be completely numb before any work begins. Sedation options are also available for patients who want additional comfort during the endodontic procedure.
3
Rubber Dam Placement
A rubber dam is placed around the tooth to isolate it from the rest of the mouth and prevent saliva from entering the treatment area during the endodontic procedure. At LA Dental Clinic, rubber dam isolation is standard for all restorative and endodontic work.
4
Access Opening and Pulp Removal
An opening is created through the crown of the tooth to reach the pulp chamber. The infected pulp, nerve tissue, blood vessels, and other cellular material are then removed from within the tooth using specific dental instruments. This is the core of the endodontic procedure.
5
Cleaning and Shaping the Root Canals
Once the pulp is removed, the root canals are cleaned and shaped using tiny files that reach down into each individual canal. The canals are also irrigated with disinfecting solutions to remove remaining bacteria and debris. This thorough cleaning is what allows the endodontic treatment to eliminate the infection.
6
Temporary Filling and Medication
After cleaning, the tooth may be left open for several days to allow any remaining infection to clear. Medication may be placed in the pulp chamber and root canals during this period. Antibiotics may also be prescribed if the bacterial infection has spread beyond the tooth.
7
Sealing the Root Canals
Once the tooth is completely clear and dry, the root canals are filled with an inert material, typically gutta-percha, and a cement seal. This blocks future bacterial entry into the now-clean canal system and completes the endodontic phase of the treatment.
8
Crown Placement
After root canal (endodontic) treatment, the tooth loses its natural hydration from the nerve and blood vessels and becomes brittle. This makes it more susceptible to fracture, particularly in molar teeth where biting forces are greatest. LA Dental Clinic typically recommends placing a crown over the treated tooth to protect it and restore full function.
LA Dental Clinic's Approach to Root Canal and Endodontic Treatment
One of the most significant aspects of LA Dental Clinic's approach to endodontics is what happens before a root canal is ever recommended. The practice's biomimetic philosophy is specifically designed to reduce the likelihood of needing endodontic treatment in the first place. By using rubber dam isolation, precise caries removal that protects the nerve, and layered biocompatible restorative materials, the biomimetic protocols used at the practice significantly increase the chance of keeping a tooth vital and avoiding root canal therapy.
When endodontic treatment is genuinely needed, LA Dental Clinic carries it out with the same clinical rigour applied to every other procedure. Dr. Arezoo Nasiry authored the practice's educational content on root canals, and Dr. Azy Nasiry's clinical focus explicitly includes saving teeth as a priority. The practice can also save teeth that another dentist might recommend extracting by offering endodontic treatment as an alternative where the tooth structure is still sufficient to support a restoration.

What Root Canal and Endodontic Treatment Achieves
The primary goal of root canal and endodontic treatment is to save the natural tooth. Extraction is the alternative when endodontic treatment is not performed or is no longer viable, and a missing tooth creates its own set of long-term problems, including bone loss, shifting of adjacent teeth, and the cost and time involved in tooth replacement.
After successful endodontic treatment, the infection is cleared, the pain resolves, and the tooth can function normally again with a crown in place. For patients who need to get back to their daily routine quickly, the endodontic procedure itself is typically completed in one to three appointments, and the tooth functions normally once the crown is placed. Most patients find the experience significantly more manageable than they expected.

"Was in the Los Angeles area for business, and my veneer came off. Not only did they answer my call at 3am but got me into see a dentist in between their already booked schedule. Once I arrived I was greeted by a very kind receptionist and a clean waiting room. I was taken back by Jose, very nice and diligent tech and then I got to meet my dentist. Like an angel for my teeth. The doctor was friendly, gentle and incredibly knowledgeable. She got me fixed up and helped me find dentist back in phx to continue my care. I am making plans to travel back to Los Angeles to see LA Dental again! Amazing!"

COMMON QUESTIONS
Frequently Asked Questions
What is endodontic treatment and how is it different from a root canal?
They are the same thing. Root canal treatment is the common name for the procedure. Endodontic therapy or endodontic treatment is the clinical term. Endodontics is the branch of dentistry that deals with the dental pulp and the tissues surrounding the roots of a tooth. When a dentist performs root canal therapy, they are performing an endodontic procedure. At LA Dental Clinic, root canal and endodontic treatment are provided in-house by Dr. Arezoo and Dr. Azy Nasiry without referral to an outside endodontic specialist.
What are the signs I may need endodontic treatment?
Signs that endodontic treatment may be needed include severe toothache when chewing, persistent sensitivity to hot or cold that does not settle quickly, swelling or tenderness in the gum near the affected tooth, darkening or discoloration of the tooth, and a persistent pimple or bump on the gum. Having experienced trauma to the face, a chipped tooth, or multiple repeat fillings on the same tooth are also factors that may indicate the need for endodontic assessment. The diagnosis is always confirmed through clinical examination and X-rays.
Is a root canal painful?
Root canal (endodontic) treatment at LA Dental Clinic is performed under local anaesthesia that fully numbs the tooth before any work begins. The procedure itself should be pain-free. Most patients report that the level of discomfort involved is similar to having a filling placed, and that the reputation root canals have for being painful is overstated. The pain associated with a root canal is typically the toothache that led up to it, not the endodontic treatment itself. Sedation options are also available at LA Dental Clinic for patients who want additional comfort during the procedure.
How many appointments does endodontic treatment take?
Root canal (endodontic) treatment at LA Dental Clinic typically takes between one and three appointments depending on the severity of the infection and the complexity of the tooth anatomy. Some straightforward cases can be completed in a single visit. Where infection has spread significantly, the tooth may need to be left open for several days with medication in place before the canals are sealed. Your dentist will advise on the expected number of visits before any treatment begins.
Why do I need a crown after a root canal?
After endodontic treatment, the tooth loses its natural hydration from the nerve and blood vessels that have been removed. This makes the tooth brittle and more susceptible to fracture, particularly under the forces generated by chewing. Molar teeth, which bear the greatest biting load, are especially vulnerable. LA Dental Clinic typically recommends placing a crown over any tooth that has undergone endodontic treatment to protect the remaining structure and restore the tooth to full function.
Can a root canal be avoided?
In some cases, yes. LA Dental Clinic's biomimetic approach is specifically designed to reduce the likelihood of needing endodontic treatment. Selective caries removal that protects the nerve, rubber dam isolation during all restorative procedures, and layered biocompatible materials all reduce the bacterial exposure and thermal stress that typically lead to pulpal damage after conventional dental work. Patients at LA Dental Clinic have a significantly higher chance of avoiding endodontic treatment compared to those treated with conventional restorative protocols. However, where the pulp is already infected or the nerve damage is beyond what conservative treatment can address, endodontic therapy is the appropriate course of action.
What happens if I do not get a root canal when I need one?
If endodontic treatment is delayed or avoided when the pulp is already infected, the infection will spread. Bacteria multiply in the pulp chamber, can move into the surrounding bone, and may cause a dental abscess. An untreated abscess can become a serious systemic health issue. The tooth will also likely need to be extracted eventually, which creates further clinical complications and cost. Endodontic treatment performed early is typically simpler, more predictable, and less expensive than managing the consequences of leaving an infected tooth untreated.
Can I fit root canal treatment around a busy schedule?
Yes. Where the endodontic procedure can be completed in a single appointment, patients can return to their normal activities immediately after. For cases that require multiple appointments, LA Dental Clinic outlines the expected visits at the start of treatment so the timeline can be planned around work and personal commitments. The tooth can function normally once the endodontic treatment and crown placement are complete, with no ongoing restrictions on activity.
