General FAQ

Endodontics is a dental specialty focused on treating diseases and injuries of the dental pulp and the tissues surrounding the roots of teeth. Endodontists are essentially root canal specialists who diagnose tooth pain and perform procedures relating to the inside of the tooth. After completing dental school, endodontists receive 2-3 years of advanced training in diagnosing tooth pain and performing root canal treatment and other procedures involving the dental pulp.

Endodontic services include specialized dental procedures focused on diagnosing and treating issues affecting the dental pulp (the soft tissue inside your tooth containing nerves, blood vessels, and connective tissue). The core services include root canal therapy, which removes infected or inflamed pulp tissue and seals the canal to prevent reinfection; endodontic retreatment for cases where previous root canal therapy hasn’t healed properly; apicoectomy (root-end surgery) when conventional treatments aren’t sufficient; treatment of dental trauma; internal bleaching for discolored teeth; and diagnosis of complex cases of dental pain.
The signs you need to see an endodontist include persistent tooth pain, sensitivity to hot or cold temperatures that lingers after the stimulus is removed, pain when biting or chewing, swelling or tenderness in the gums near a painful tooth, discoloration of a tooth, and a pimple-like bump on the gums. Additionally, if you’ve experienced dental trauma, such as a broken or cracked tooth, or if you’ve been referred by your general dentist for a complex case, you should see an endodontist promptly.
Most dental insurance plans cover endodontic procedures, though coverage varies between policies. Typically, root canal treatments are categorized as “major procedures” and are covered at 50-80% of the cost after you’ve met your deductible. Coverage depends on your specific plan’s annual maximums, waiting periods, and whether your endodontist is in-network with your insurance provider.
The main difference between an endodontist and a general dentist is specialization and training. Endodontists complete an additional 2-3 years of specialized education beyond dental school, focusing specifically on diagnosing tooth pain and performing procedures related to the dental pulp. While general dentists can perform basic root canal procedures, endodontists perform these treatments daily, developing significant expertise in complex cases. Endodontists use specialized equipment like surgical operating microscopes and 3D imaging technology for greater precision.

Apicoectomy & microsurgery FAQ

View service

No. A root canal treats infection from inside the tooth, while an apicoectomy treats infection at the tip of the root—usually when a previous root canal has failed. It’s a microsurgical solution used to preserve your natural tooth.

If you’ve had a root canal but still experience pain, swelling, or signs of infection, your dentist or endodontist may recommend an apicoectomy. At Liv Endodontics in Livingston and Summit, we use CBCT imaging to confirm if it’s the right treatment.

Not at all. The procedure is done under local anesthesia, and we offer sedation options for added comfort. Most patients report only mild soreness after surgery.

Most people resume normal activity within 1–2 days. Full healing may take a few weeks. We’ll provide detailed aftercare instructions and monitor your recovery closely.

Modern apicoectomies have a success rate of over 90% when performed with advanced imaging and microsurgical tools—both standard at Liv Endodontics.

If your tooth already has a crown, it typically stays in place. If not, your general dentist may recommend one to protect the tooth after healing.

Like any procedure, there’s a small chance of failure—usually due to complex anatomy or untreated infection. However, our high-tech tools and surgical expertise greatly reduce that risk.

Many insurance plans cover part or all of the cost, especially if the tooth was previously treated with a root canal. We’ll help you confirm your coverage and explain your options.

Delaying treatment can allow the infection to spread to surrounding bone and tissue, possibly leading to tooth loss or more invasive surgery. Early action helps preserve your tooth and avoid complications.

Cracked tooth treatment FAQ

View service
Not all cracks are visible. Common symptoms include sharp pain when chewing, sensitivity to temperature, or swelling around a specific tooth. If you’re in Livingston or Summit and suspect a crack, schedule a CBCT scan with our team for a precise diagnosis.
No. Once a tooth is cracked, it will not regenerate or heal naturally. Delaying treatment increases the risk of infection, further fracture, or even tooth loss.

If the crack has reached the pulp (inner tissue), a root canal is typically required to remove damaged tissue, stop pain, and save the tooth. We’ll determine this using advanced 3D imaging and microscope evaluation.

Common causes include chewing hard foods (like ice or nuts), teeth grinding (bruxism), age-related wear, previous dental work, or trauma. Identifying the cause helps us prevent future damage.
Not at all. We use local anesthesia and offer sedation options to keep you comfortable during the procedure. Most patients report little to no discomfort at our Livingston and Summit offices.
Costs vary depending on the severity of the crack and whether a root canal or crown is needed. We’ll provide a transparent estimate during your consultation and explain insurance or payment options.
An untreated crack can worsen over time, leading to infection, pain, or even the need for extraction. Early treatment dramatically improves the chances of saving your natural tooth.

In most cases, yes. A crown protects the tooth from further damage and restores strength. Your general dentist will complete this final step after root canal treatment, if needed.

We can often perform diagnostic imaging and root canal treatment in the same day. If the case is urgent, we offer same-day appointments at both our Livingston and Summit locations.

Yes. Each case is evaluated individually. Molars experience more bite pressure and may require more reinforcement. Our advanced imaging ensures the treatment plan is tailored to your specific tooth.

Emergency dentistry FAQ

View service
Severe tooth pain, swelling, visible abscesses, or trauma like a cracked tooth are all considered dental emergencies—especially when the pulp is involved. At Liv Endodontics, we treat emergencies related to internal tooth damage from our Livingston and Summit locations
If the pain involves deep sensitivity, swelling, or signs of infection, an endodontist is the best choice. We specialize in root canal treatment, abscess drainage, and cracked tooth repair—often the most effective solutions in urgent situations.

No. We offer multiple sedation options, including IV sedation and nitrous oxide, to ensure a comfortable, stress-free experience—even in emergency situations.

Laser-assisted endodontics FAQ

View service
Laser-assisted endodontics uses advanced laser technology to enhance the cleaning step of root canal treatment. The laser reaches into complex canal anatomy where traditional instruments cannot fully access, removing bacteria and debris for a deeper, more thorough clean.
Standard cleaning uses instruments and irrigating solutions to remove tissue and bacteria. Laser-assisted endodontics adds a step that reaches deep into complex canal anatomy, removing up to 99% of bacteria commonly found in the root canal system.
Yes. The laser technology we use is FDA-cleared and trusted by endodontic specialists. It targets bacteria and biological material while leaving healthy tooth structure intact.
Not necessarily. Your endodontist will evaluate your tooth anatomy and infection level to determine whether laser-assisted endodontics is the right addition to your treatment plan.
A consultation is the best way to find out. We use 3D imaging to assess your canal anatomy and talk through whether laser-assisted endodontics is right for your case. Patients with complex anatomy or a prior root canal are often strong candidates.
EdgePRO® is the specific laser technology we use at Liv Endodontics to perform laser-assisted endodontics. It pulses light energy deep into the canal walls, reaching areas where conventional instruments and irrigating solutions may fall short.
No. Most patients are pleasantly surprised by how comfortable treatment is, and recovery tends to be smooth. Sedation options are also available for patients who want extra peace of mind.
Coverage varies by plan. Our team will review your insurance and walk you through a clear cost estimate before treatment begins — no surprises.
Yes. Laser-assisted endodontics with EdgePRO® laser technology is available at both our Livingston and Summit, NJ offices, Monday through Saturday.
After the canals are cleaned and sealed, your general dentist will place a crown to protect the tooth. Most patients get back to their normal routine quickly, with minimal discomfort.

Lightening discolored teeth FAQ

View service

Most patients experience little to no discomfort. Mild sensitivity is possible during the whitening process but typically resolves quickly.

Results vary. Some teeth respond after one treatment, while others require two to three rounds to achieve the desired shade.

Internal bleaching results can last for many years, though touch-ups may be needed in the future depending on lifestyle factors and the original cause of discoloration.

This procedure is typically best for non-vital (root canal-treated) front teeth. Your endodontist will evaluate your case to confirm eligibility.

Pricing varies based on the number of treatments needed. We’ll give you a clear estimate at your consultation and explain financing or insurance options available.

In rare cases, if internal bleaching isn’t sufficient, we may refer you for a cosmetic restoration like a veneer or crown to achieve the desired appearance.

Root canal retreatment FAQ

View service
Not at all. With modern anesthesia and sedation, retreatments are typically just as comfortable as the initial procedure. Most patients in our Livingston and Summit offices report only minor post-op soreness.
Root canal retreatments usually take 60–90 minutes, depending on the tooth and complexity. Additional time may be needed if previous materials or missed canals are difficult to access.
Common reasons include missed canals, reinfection, a delayed crown placement, or a new fracture. Our CBCT imaging helps us identify what went wrong and target it precisely.

Fees vary based on tooth location and complexity. We’ll provide a transparent estimate before treatment and help you navigate insurance or financing options.

Very high. With advanced tools like EdgePRO® laser cleaning and microscope guidance, retreatment can often save the tooth and relieve symptoms effectively—even when prior treatment failed.
In most cases, your general dentist will place a new crown or restore the old one if it’s still in good condition. Protecting the tooth afterward is key to long-term success.
Whenever possible, saving your natural tooth is ideal. Retreatment is less invasive, more cost-effective, and avoids the need for an implant or bridge. We’ll help you determine the best option for your case.

Untreated infection can spread, cause pain, damage the bone, and lead to tooth loss. Early retreatment gives you the best chance at preserving your natural tooth.

As soon as possible. The longer you wait, the more complicated the infection can become. We offer same-day appointments in Livingston and Summit when urgent pain returns.

Root canal therapy FAQ

View service
Modern techniques and sedation make discomfort minimal—most patients compare it to a routine filling.
Typically 60–90 minutes in our Livingston and Summit offices. More complex cases may require additional time under microscope guidance.

Yes. A crown placed by your restorative dentist protects the treated tooth, restores its strength, and ensures long-term function.

We provide nitrous oxide (“laughing gas”), oral sedation, and IV sedation for a calm, stress-free experience tailored to your comfort level.

Fees vary by case complexity. We’ll give you a transparent estimate before treatment and can assist with insurance filing.

Infection can develop inside the tooth without obvious pain until it reaches advanced stages. Early root canal therapy stops the spread of bacteria and prevents more extensive—and expensive—treatment down the road.
Delaying treatment allows infection to worsen, potentially leading to abscesses, bone loss, and tooth loss. You may also experience more severe pain and require more complex surgery.
Mild soreness or tenderness for 1–2 days is common and typically managed with over-the-counter pain relievers. Persistent or severe pain should be evaluated promptly.
Good oral hygiene, regular cleanings, and prompt treatment of decay or cracks reduce the risk of pulp infection. However, once bacteria reach the tooth’s interior, only a root canal (or extraction) can resolve the issue.
Antibiotics can temporarily control bacterial spread but don’t remove infected tissue inside the tooth. Definitive treatment requires disinfecting and sealing the canals via root canal therapy.

Don't wait. Tooth infections can escalate quickly!

A tooth infection is a serious oral health risk that demands expert care without delay. If you suspect you need root canal therapy or another endodontic procedure, contact Liv Endodontics immediately.
