Endodontic FAQ

About Endodontic Care

What is endodontics?

Endodontics is the dental specialty concerned with the diagnosis and treatment of conditions affecting the interior of a tooth, including the dental pulp, root canals, and surrounding bone. When the pulp becomes infected, inflamed, or injured, endodontic treatment is typically the most reliable way to address the source of the problem and preserve the natural tooth.

What does an endodontist do?

An endodontist is a dental specialist who completes two to three years of advanced post-doctoral training beyond dental school, focused exclusively on the diagnosis and treatment of conditions affecting the dental pulp and root canal system. Endodontists perform root canal treatment, retreatment, endodontic surgery, and the evaluation and management of cracked teeth and dental trauma. Because endodontics is their sole focus, endodontists develop a depth of clinical experience with complex cases that extends beyond the scope of general dental practice.

Why was I referred to an endodontist?

A referral to an endodontist typically means your dentist has identified a situation that warrants specialist evaluation. Common reasons include complex canal anatomy, persistent or recurrent infection, a suspected crack, a tooth that has already been treated and is not healing as expected, or a case that requires surgical intervention. Escondido Endodontics accepts referrals from general dentists and specialists throughout Escondido, San Marcos, Vista, Poway, and North County San Diego.

What is the difference between an endodontist and a general dentist?

General dentists provide a broad range of preventive, restorative, and cosmetic care. Endodontists complete additional specialty training after dental school that focuses entirely on the pulp, root canals, and surrounding structures. This narrowed focus allows endodontists to manage cases with greater diagnostic precision, access advanced imaging tools such as cone beam CT (CBCT), and perform procedures such as apicoectomy that fall outside the scope of most general practices.

Do I need a referral to see an endodontist?

A referral from your general dentist is the most common path to endodontic care, and it helps ensure continuity between your specialist treatment and your restorative plan. Patients in Escondido and the surrounding North County San Diego area with acute dental pain or an urgent concern are welcome to contact our office directly.

Root Canal Treatment

What is a root canal?

A root canal is a procedure that removes infected or inflamed pulp tissue from inside a tooth, cleans and shapes the internal canal system, and seals it to prevent reinfection. The goal is to eliminate the source of infection or inflammation while preserving the natural tooth structure.

How do I know if I need a root canal?

Common indicators include persistent or severe tooth pain, sensitivity to heat or cold that lingers after the source is removed, pain when biting or chewing, swelling or tenderness in the gum tissue near a tooth, or a tooth that has darkened. Some teeth that require treatment produce no noticeable symptoms at all, which is why a clinical exam and 3D imaging are essential for an accurate diagnosis. Symptoms alone are not sufficient to determine whether root canal treatment is needed.

Is a root canal painful?

Root canal treatment is performed with local anesthesia. Most patients report that the procedure is no more uncomfortable than having a filling placed. Some tenderness in the treated area for a few days following the appointment is normal and typically responds well to over-the-counter pain relief. The procedure itself is designed to relieve pain, not cause it.

How long does a root canal take?

Most root canals are completed in a single appointment lasting one to two hours, depending on the tooth involved and the complexity of its canal anatomy. Posterior teeth with multiple canals, cases with extensive infection, or teeth with unusual anatomy may require an additional visit.

Will the tooth be dead after the pulp is removed?

No. After root canal treatment, the tooth retains its attachment to surrounding tissues and continues to receive nutrients through the periodontal ligament. It is no longer vital in the traditional sense, meaning its internal nerve is no longer functional, but it remains an integrated part of the dentition and can last for many years with appropriate restoration and maintenance.

Can I return to work or normal activity the same day?

Most patients are able to return to work or regular activities the same day. Some soreness or mild sensitivity in the area is common for the first day or two. We recommend avoiding chewing directly on the treated tooth until your permanent restoration is in place.

What happens if I do not get a root canal?

An infected or inflamed pulp does not resolve on its own. Leaving it untreated allows infection to progress into the surrounding bone and soft tissue, which can lead to abscess formation, bone loss, and the spread of infection to adjacent structures. Over time, an untreated endodontic infection may become a more serious health concern and often results in the loss of the tooth.

What is the difference between a root canal and a tooth extraction?

A root canal treats the tooth from within and preserves the natural tooth structure. An extraction removes the tooth entirely. When a tooth can be saved through endodontic treatment, preservation is generally preferable. Natural teeth support surrounding bone, maintain bite function, and preserve the position of adjacent teeth in a way that replacement options, while effective, do not fully replicate.

Advanced Technology

What is CBCT imaging and why does it matter for root canal treatment?

Cone beam computed tomography (CBCT) is a 3D imaging technology that produces detailed cross-sectional views of a tooth, its root canals, and the surrounding bone. Unlike conventional dental X-rays, which are two-dimensional, CBCT imaging allows the treating endodontist to evaluate the full three-dimensional extent of infection, identify missed or accessory canals, assess root fractures, and detect anatomical variations that would not be visible on a standard radiograph. This level of detail improves diagnostic accuracy and supports more precise treatment planning.  At Escondido Endodontics, CBCT imaging is available in-office and used when it will provide clinically meaningful information that a conventional X-ray cannot.

Do endodontists use surgical microscopes?

Surgical microscopes provide high levels of magnification and illumination that allow endodontists to see the interior of a tooth with a level of detail not possible with the naked eye or standard loupes. They are particularly valuable during root canal treatment, retreatment, and surgery, where identifying additional canals, locating calcified spaces, and assessing the extent of cracks can have a direct effect on the outcome.  At Escondido Endodontics, surgical microscopes are used during treatment to support precision at each stage of care.

How is 3D imaging different from a regular dental X-ray?

A conventional dental X-ray produces a two-dimensional image that overlays all structures onto a single flat plane. CBCT imaging produces a three-dimensional data set that can be viewed in multiple planes, including cross-sections that reveal structures not visible on standard film. For endodontic purposes, this distinction is clinically significant when evaluating complex canal anatomy, ruling out vertical root fractures, assessing bone involvement around an infection, or planning surgical access.

Endodontic Retreatment

Why would a tooth that already had a root canal need retreatment?

A previously treated tooth may require retreatment if it does not heal as expected, develops new infection, or if a missed canal, untreated anatomy, a cracked root, or a compromised restoration allowed bacteria to re-enter the canal system over time. Retreatment is also considered when a tooth develops new symptoms after a period of apparent healing.

Is retreatment as effective as the original root canal?

Retreatment can be highly effective when the underlying cause of the problem is identified and properly addressed. The success of retreatment depends on the condition of the tooth, the reason for failure, and the degree to which the canal system can be adequately cleaned and sealed. A thorough evaluation, including 3D imaging, before retreatment is essential to determining whether it is the appropriate course of action and to planning the procedure accurately.

What are the alternatives if retreatment is not an option?

If the tooth cannot be retreated non-surgically, endodontic surgery such as an apicoectomy may be considered to address infection or pathology at the root tip directly. In cases where neither retreatment nor surgery is feasible and the tooth cannot be preserved, extraction followed by a restorative option such as a dental implant may be discussed.

Endodontic Surgery

What is an apicoectomy?

An apicoectomy, also called endodontic microsurgery or root-end surgery, is a procedure used to address persistent infection or pathology at the tip of a tooth’s root when non-surgical root canal treatment or retreatment has not fully resolved the problem. The procedure involves a small incision in the gum tissue, removal of the infected tissue and a portion of the root tip, and placement of a small filling to seal the root end. It is performed under surgical microscope magnification, which allows a level of precision and detail not possible without magnification.

When is endodontic surgery recommended?

Endodontic surgery is typically recommended when infection or inflammation persists at the root tip after root canal treatment or retreatment, when the root canals cannot be accessed non-surgically due to posts, calcification, or blocked anatomy, when a fracture or root resorption requires direct visualization and management, or when a diagnostic lesion requires tissue biopsy.

How long is recovery after endodontic surgery?

Most patients return to normal daily activity within two to three days. Some swelling, bruising, and mild discomfort in the surgical area is expected during the first few days and can generally be managed with over-the-counter pain relief and cold application. Full bone healing around the treated root tip takes several months. Most patients experience minimal disruption to daily life beyond the initial recovery period.

Cracked Teeth

How do I know if I have a cracked tooth?

Cracked teeth are among the more challenging diagnoses in dentistry because cracks are often not visible on X-rays, and symptoms can be intermittent and difficult to localize. Common signs include sharp pain when biting or releasing bite pressure, sensitivity to temperature that does not follow the typical pattern of decay, and discomfort that moves or cannot be pinpointed to a specific tooth. A clinical exam, CBCT imaging, and evaluation under surgical microscope magnification are often needed to confirm the diagnosis and assess the extent of the crack.

Can a cracked tooth be saved?

Many cracked teeth can be treated successfully, depending on the type and depth of the crack. A crack confined to the crown of the tooth or the upper portion of the root may be treatable with root canal therapy and a crown. A vertical root fracture that extends through the root structure is more difficult to address and in some cases is not salvageable. Early evaluation is the most significant factor in determining whether and how the tooth can be preserved.

What causes teeth to crack?

Common contributing factors include habitual grinding or clenching, biting on hard foods or objects, large existing restorations that alter the mechanical load distribution of the tooth, previous trauma to the mouth, and repetitive thermal cycling from significant temperature changes over time.

Endodontic Emergencies

What qualifies as an endodontic emergency?

Severe or rapidly worsening tooth pain, significant facial or jaw swelling, a tooth that has been knocked out or displaced by trauma, or a tooth that is fractured at or below the gum line all warrant prompt evaluation. Difficulty breathing or swallowing in conjunction with dental pain or swelling requires immediate care at an emergency room rather than a dental office.

Can I be seen the same day for a dental emergency in Escondido?

We make every effort to accommodate same-day appointments for urgent endodontic situations. We serve patients in Escondido, San Marcos, Vista, Poway, and surrounding communities in North County San Diego. We recommend calling our office directly so a member of our team can assess the situation and schedule you as promptly as possible.

Should I go to the emergency room or contact an endodontist for tooth pain?

For tooth pain or suspected dental infection without systemic symptoms, an endodontist can evaluate and treat the underlying cause more directly than an emergency room, which is not equipped to provide definitive endodontic care. If you are experiencing rapidly spreading facial swelling, a high fever alongside dental pain, difficulty breathing, or difficulty swallowing, go to the nearest emergency room immediately. Dental infections that spread to adjacent tissue spaces can become serious and require medical management beyond the scope of a dental office.

What should I do if a tooth gets knocked out?

Handle the tooth by the crown only and avoid touching the root surface. Rinse the tooth gently without scrubbing. Reposition it in the socket if possible and bite gently to hold it in place, or keep it moist in milk, saline, or your own saliva. Contact our office or an emergency dental provider immediately. Time from the moment of injury is the most significant factor in determining the prognosis for a replanted tooth.

Recovery and Aftercare

What can I eat after a root canal?

Soft foods are recommended for the first day or two following treatment. Avoid chewing directly on the treated tooth until your permanent restoration is placed, as the tooth is more susceptible to fracture during that interim period. Your general dentist will advise on timing for the final crown or restoration.

Is sensitivity after root canal treatment normal?

Some tenderness and sensitivity in the treated area for a few days following the procedure is a normal part of healing. If pain is severe, increasing rather than decreasing, or accompanied by swelling, contact our office so the area can be evaluated. Worsening symptoms beyond the expected window of normal healing are worth reporting.

Do I need a crown after a root canal?

In most cases, yes. A crown restores the structural integrity of the treated tooth and significantly reduces the risk of fracture. Anterior teeth occasionally may not require a full crown, but posterior teeth, which bear significant chewing forces, almost always do. Your general dentist will determine the appropriate final restoration and timing after treatment at our office is complete.

Insurance and Appointments

Does insurance cover root canal treatment?

Most dental insurance plans provide at least partial coverage for endodontic treatment. Coverage varies by plan, by tooth type, and by the specific procedure involved. Our team at Escondido Endodontics will file your claim directly and help you understand your benefits before treatment begins.

For Referring Doctors

This section is for general dentists and specialists who refer patients to Escondido Endodontics.

How do I refer a patient to Escondido Endodontics?

You can refer a patient by phone, through our online referral form, or by having the patient contact our office directly with your referral information. We accept referrals from general dentists and dental specialists throughout Escondido, San Marcos, Vista, Poway, and the broader North County San Diego region. Our team will contact the patient promptly to schedule and will keep you informed throughout the process.

How quickly can urgent referrals be seen?

We prioritize patients with acute pain, swelling, or dental trauma and make every effort to schedule urgent referrals the same day or next day. Referring doctors throughout Escondido, San Marcos, Vista, and Poway can call our office directly for time-sensitive cases.

What communication can I expect after you treat my patient?

Following each appointment, we provide a written report to the referring dentist that includes the diagnosis, treatment completed, clinical findings, post-treatment status, and recommendations for final restoration. Our goal is to ensure that you have the information you need to complete your patient’s care without delay.

What types of cases do you prefer to receive by referral?

We accept a wide range of endodontic referrals, including routine root canal treatment on complex cases, retreatment of previously treated teeth, endodontic microsurgery, evaluation and management of cracked teeth, traumatic dental injuries, and cases where diagnostic clarification with CBCT imaging would be beneficial. If you are uncertain whether a case is appropriate for referral, contact our office, and we are glad to discuss it with you.

Do you perform endodontic surgery in-office?

Yes. Endodontic microsurgery, including apicoectomy procedures, is performed in our office under surgical microscope magnification. We have the technology and training to manage complex surgical referrals without the need to send patients to an outside surgical facility.

What technology do you use for referred cases?

We have CBCT imaging and surgical microscopes available in-office. For complex cases involving uncertain anatomy, suspected fractures, or resorption, CBCT imaging allows us to evaluate the situation three-dimensionally and communicate findings to you with greater specificity than conventional radiographs permit.

Will you coordinate with me on the restorative plan?

Yes. Our treatment reports include recommendations for final restoration, and we are available to discuss the restorative plan with you directly when a case warrants it. We treat endodontic care as one phase of an integrated treatment plan and aim to make the transition back to your office as smooth as possible.

How soon should a referred patient return to my office after endodontic treatment?

In most cases, we recommend that patients return to their restorative dentist within four to six weeks following root canal treatment to have a permanent restoration placed. Leaving a treated tooth without a final crown or build-up beyond that window increases the risk of fracture or contamination. We will note this recommendation in our report and reinforce it with the patient at their appointment.

Do you see pediatric patients?

Yes, we do see younger patients when endodontic treatment is indicated. If you are referring a child, we are glad to discuss the case with you before the appointment to ensure the visit is appropriate for your patient’s needs and that any additional considerations are addressed in advance.
