Gentle Root Canal Therapy in Johnson City, TN

Pain Relief & Tooth Preservation Dr. John Nauss, DMD ★★★★★ 5.0 on Google
Endodontic Tooth Preservation

Relieve severe toothache pain and save your natural tooth with gentle root canal therapy.

When tooth decay or trauma penetrates deep into the inner pulp chamber of a tooth, the nerve becomes inflamed and infected, causing severe, throbbing pain.

Root canal therapy is a gentle, routine procedure that removes the infected nerve tissue, disinfects the microscopic internal canals, and seals the tooth to save it from extraction.

Contrary to outdated myths, modern root canal therapy does not cause pain; it relieves pain. Dr. John Nauss utilizes advanced rotary endodontic instruments and gentle local anesthesia, with nitrous oxide available, to keep your procedure fast, quiet, and comfortable.

Why Save Your Natural Tooth?

Saving your natural tooth root preserves jawbone density and avoids the cost of extraction and replacement.

  • Immediate Pain Relief: Removes inflamed, dying nerve tissue, eliminating throbbing pain, abscess pressure, and sensitivity.
  • Preserves Natural Tooth Structure: Keeps your natural tooth in place, preserving natural chewing mechanics and neighboring tooth alignment.
  • Prevents Spread of Infection: Stops bacteria from spreading into the surrounding jawbone, facial spaces, or bloodstream.
  • Same-Day Crown Available: In many cases, the protective crown can be designed and placed in our office the same day with CEREC.

The Root Canal Procedure Steps

Dr. Nauss thoroughly numbs the tooth and places a protective rubber dam to keep the area sterile. A microscopic access opening is made in the crown of the tooth.

Precision nickel-titanium rotary files gently clean and shape the microscopic root canals. The canals are disinfected with antimicrobial rinses, sealed with biocompatible gutta-percha, and prepared for a protective ceramic crown.

Post-Treatment Recovery

Most patients experience immediate relief from their throbbing toothache. Mild tenderness around the gumline for 24 to 48 hours is easily managed with ibuprofen. Avoid chewing hard foods on the tooth until your crown is seated.

Common Questions

Root Canals FAQ.

Frequently asked questions regarding root canal therapy, pain management, and tooth recovery.

Does a root canal hurt?

No. With modern local anesthesia and rotary instruments, a root canal feels much like getting a standard filling, and nitrous oxide is available if you'd like help relaxing. The procedure actually relieves the pain caused by the infected nerve.

What are the symptoms of an infected tooth nerve?

Common symptoms include persistent throbbing pain, lingering sensitivity to hot and cold, swelling or tenderness in the nearby gums, pain when biting, and a pimple-like bump on the gums (fistula).

How long does a root canal procedure take?

Most root canals are completed comfortably in a single 60 to 90 minute appointment.

Why is a crown necessary after a root canal?

Once the nerve and blood supply are removed, the remaining tooth structure becomes brittle. A crown helps protect the tooth from cracking under chewing forces, and most crowns can be made in our office the same day.

Can an infected tooth heal on its own with antibiotics?

No. Antibiotics can temporarily reduce symptoms in the surrounding tissue, but they cannot reach bacteria inside the root canal space. Physically removing the infection with a root canal is required.

Does dental insurance cover root canal therapy?

Many plans cover part of a root canal. We're in network with Delta Dental Premier only, we'll help you file out-of-network claims with other plans, and we offer financing and a membership plan.
