HCPCS code

#### Name of the Procedure:
Retreatment of Previous Root Canal Therapy-Bicuspid (D3347)

#### Summary
This procedure involves re-treating a previously performed root canal on a bicuspid tooth. It aims to clear out the previously treated root canal which may have become infected or failed, and to restore the health of the tooth.

#### Purpose
The primary goal is to address infection or persistent problems in a previously treated root canal of a bicuspid tooth. The procedure aims to eliminate the source of infection, alleviate pain, and save the tooth from extraction.

#### Indications
- Persistent pain or discomfort in the tooth
- Evidence of infection, abscess, or swelling
- Failure of initial root canal therapy
- Radiographic signs of continued infection

#### Preparation
- Patients should inform their dentist of any medications they are taking or any underlying health conditions.
- Pre-procedure diagnostic X-rays to assess the extent of the infection.
- No need for fasting unless sedation is planned.

#### Procedure Description
1. Local anesthesia is administered to numb the area.
2. A dental dam is placed to isolate the tooth.
3. The dentist reopens the tooth to access the root canal filling material.
4. Special instruments are used to remove the old root canal filling.
5. The canals are thoroughly cleaned, disinfected, and reshaped.
6. The canals are refilled and sealed with a new filling material.
7. The opening is sealed with a temporary or permanent filling.

#### Duration
Typically, the procedure takes around 60 to 90 minutes, depending on the complexity.

#### Setting
This procedure is usually performed in a dental office or an outpatient dental clinic.

#### Personnel
- Endodontist or general dentist
- Dental assistant

#### Risks and Complications
- Risk of re-infection
- Tooth fracture or cracking
- Incomplete removal of old filling material
- Temporary or prolonged discomfort

#### Benefits
- Relief from pain and infection
- Avoidance of tooth extraction
- Restoration of normal tooth function

#### Recovery
- Mild discomfort that can be managed with over-the-counter pain relievers
- Avoid eating hard foods and chewing directly on the treated tooth for a few days
- Follow-up appointment to monitor healing and possibly place a permanent crown

#### Alternatives
- Tooth extraction followed by dental implant, bridge, or denture
- Pros: Extraction may completely eliminate infection.
