Medications and Management for Root Canal Treatment

Dr.
Liu: I have been seeing the same dentist for over a decade for my dental issues.
Since she left her practice, I went to a new clinic near my home for a routine check-up.
The new dentist indicated that the tooth I had previously treated with a crown seems to have developed new decay.
After removing the crown for inspection, the dentist informed me that the previous treatment was incomplete and that the decay was very close to the tooth root.
If I were to undergo retreatment and get a new crown, there is a high risk of developing periodontal disease in the future.
The dentist suggested extracting the tooth and getting an implant, or possibly getting a new crown for the entire row of teeth, since the three front teeth also have crowns.
This means I would need to replace five crowns altogether, which feels very cumbersome to me.
I wonder if it would be better to try to save the original tooth by undergoing retreatment with a root canal and getting a new crown instead.
Is retreatment really that complicated? When I decided to proceed with the retreatment and get a new crown, the dentist asked me to think it over at home, which left me uncertain.
Ultimately, when I went ahead with the retreatment, the dentist used a syringe to inject disinfectant into the root canal, but the solution ended up in my mouth, and due to excessive saliva production, it flowed down my throat and I swallowed some.
The dentist did not use a suction device to remove the excess saliva, nor did he allow me to rinse or spit it out.
It felt as if I had ingested a strong acid, causing discomfort and nausea in my throat.
When I asked the dentist about it afterward, he said it was fine, but since my visit in the morning, my throat has been uncomfortable whenever I drink anything.
Could that solution harm my esophagus or throat? Should I see an ENT specialist for an examination?

Hello: During the root canal treatment process, it is essential to frequently irrigate the root canal with disinfectant solutions to achieve sterilization and flush out debris, preventing blockage within the canal.
The most commonly used disinfectant irrigant is sodium hypochlorite (bleach).
Due to its irritating effects on oral mucosa, a rubber dam should typically be placed to isolate the tooth during the procedure to prevent leakage into the mouth.
If accidental leakage occurs, it is important to rinse the mouth immediately to avoid the risk of mucosal ulcers.
If you have swallowed the solution, you should seek evaluation and treatment from an otolaryngologist.
Sincerely, Dr.
Liu Tian-Cai, Dentistry.

More Info

Root canal treatment (RCT) is a common dental procedure aimed at treating infection or damage to the pulp of a tooth. It involves the removal of the infected or damaged pulp, cleaning and disinfecting the root canals, and then filling and sealing them to prevent further infection. While RCT is generally effective, patients may experience discomfort or pain during and after the procedure. Understanding the medications used and the procedures involved can help alleviate concerns and improve patient outcomes.

Medications Used in Root Canal Treatment
1. Antibiotics: Antibiotics like Keflex (cephalexin) may be prescribed if there is a bacterial infection present. They help to eliminate bacteria that could complicate the healing process. However, antibiotics are not always necessary unless there is clear evidence of infection, such as swelling or fever.

2. Pain Relievers: Over-the-counter pain relievers such as ibuprofen or acetaminophen (Tylenol) are often recommended to manage post-treatment pain. Ibuprofen is a non-steroidal anti-inflammatory drug (NSAID) that can help reduce inflammation and pain. It is generally safe to take ibuprofen and acetaminophen together, but patients should always consult their dentist or physician before combining medications.

3. Local Anesthetics: During the procedure, local anesthetics are used to numb the area around the tooth to minimize discomfort. If a patient continues to feel pain despite the anesthetic, it may indicate that additional treatment is needed or that the infection is more severe than initially assessed.

4. Disinfectants: During the RCT, disinfectants are injected into the root canals to kill bacteria and clean the area. While these solutions are generally safe, they can cause temporary discomfort if they come into contact with sensitive tissues in the mouth or throat.

The Procedure
The root canal procedure typically involves several steps:
1. Diagnosis: The dentist will take X-rays to assess the condition of the tooth and the extent of the infection.

2. Anesthesia: Local anesthesia is administered to numb the tooth and surrounding area.

3. Access Opening: The dentist drills an opening in the crown of the tooth to access the pulp chamber.

4. Pulp Removal: The infected or damaged pulp is removed using specialized instruments.

5. Cleaning and Shaping: The root canals are cleaned, shaped, and disinfected to prepare them for filling.

6. Filling: The cleaned canals are filled with a biocompatible material called gutta-percha, and the access opening is sealed.

7. Restoration: After the root canal, a crown or filling is usually placed to restore the tooth's function and appearance.

Post-Procedure Care and Concerns
After the procedure, it is normal for patients to experience some discomfort or pain as the area heals. However, if the pain is severe or persists for an extended period, it is crucial to follow up with the dentist. Persistent pain may indicate that not all infected tissue was removed or that there is another underlying issue.

Regarding the discomfort in the throat after swallowing disinfectant solution, it is advisable to monitor the symptoms. If the discomfort persists or worsens, consulting an ear, nose, and throat (ENT) specialist may be warranted to rule out any potential damage or irritation.

Conclusion
In summary, root canal treatment is a valuable procedure for saving teeth that would otherwise need to be extracted. While it can be uncomfortable, understanding the medications used and the steps involved can help patients feel more at ease. If you have concerns about pain management or post-treatment symptoms, do not hesitate to communicate with your dentist. They can provide guidance tailored to your specific situation and ensure that you receive the best possible care.
