There are many reasons why a tooth may require root canal therapy. A deep cavity may enter the nerve chamber in the tooth causing the tooth to become painful and infected or the tooth may have been traumatized in a fall or while playing sports causing the nerve inside the tooth to become infected and discolored. Whatever the cause may be, root canal treatment (endodontic treatment) removes the infected, dying nerve from the tooth allowing the patient to keep there own tooth in their mouth rather needing an extraction. After the root canal treatment is completed the tooth is most often restored with a crown to make the tooth strong and whole again. Dr. Tischler is aware of the apprehension and anxiety that many patients experience when told they require root canal therapy and uses his years of experience doing endodontic treatment in Rego Park, Queens, NY to make root canal therapy as pain free as possible. At CLT Dentistry, Dr. Tischler makes use of local anesthetics, Nitrous Oxide Gas (Sweet Air) and medications to make your root canal experience as pleasant as possible.
