Q: Should I Get a Filling for My Sharp Tooth After Root Canal?

Dear Anonymous Miss： Hello! After undergoing a root canal treatment, the tooth needs to be restored before placing a crown. <br>Take care! Wishing you all the best and smooth recovery! Sincerely, Dr. <br>Huang Ting-Fang, Dentistry.

After a root canal treatment, the filling material in the tooth may become pointed?

Hello, doctor.
I previously had a cavity in my molar that I didn't address, which eventually led to a root canal.
The root canal was filled, but I haven't had a crown placed.
Now, the back of the tooth is sharp, and the front has sunken in.
Should I get this tooth filled again? (The teeth adjacent to the molar are causing some pain when biting, so I had some tissue trimmed.)

More Info

After undergoing a root canal treatment, it is crucial to address any structural issues with the tooth, especially if it has become sharp or has lost its normal shape. In your case, since the tooth has developed a sharp edge and has not been covered with a crown, it is advisable to consider getting a filling or some form of restoration.

Why You Should Consider a Filling
1. Protection Against Further Damage: A filling can help restore the tooth's shape and protect it from further decay or damage. Without proper restoration, the tooth is more susceptible to fractures, especially since it has already undergone a root canal, which can weaken the tooth structure.

2. Pain Management: You mentioned experiencing some pain when biting down on adjacent teeth. This discomfort could be due to the sharp edge of the tooth causing trauma to the surrounding soft tissues or misalignment in your bite. A filling can help alleviate this pain by smoothing out the sharp edges and restoring proper occlusion.

3. Preventing Infection: An unprotected tooth can be at risk for reinfection. The filling will seal the tooth and help prevent bacteria from entering the pulp chamber, which could lead to further complications.

4. Aesthetic Considerations: If the tooth is visible when you smile, a filling can also improve the aesthetics of your smile by restoring the tooth to a more natural shape.

What to Discuss with Your Dentist
When you visit your dentist, it’s essential to discuss the following:
- Type of Filling: There are various materials available for fillings, including composite resin, amalgam, and glass ionomer. Your dentist can help you choose the best option based on the location of the tooth, your dental health, and your budget.

- Need for a Crown: Given that the tooth has undergone a root canal, your dentist may recommend placing a crown instead of just a filling. A crown provides more comprehensive coverage and protection, especially for molars that endure significant chewing forces.

- Bite Adjustment: Since you mentioned that the adjacent teeth are experiencing discomfort, your dentist should evaluate your bite and make any necessary adjustments to ensure that all teeth align properly after the filling or crown is placed.

Temporary Solutions
If you are unable to get to the dentist immediately, here are some temporary measures you can take:
- Avoid Hard Foods: Stick to soft foods to prevent further damage to the tooth and minimize discomfort.

- Maintain Oral Hygiene: Keep the area clean by brushing gently and using an antibacterial mouthwash to reduce the risk of infection.

- Pain Management: Over-the-counter pain relievers can help manage any discomfort until you can see your dentist.

Conclusion
In summary, it is advisable to get a filling or some form of restoration for your sharp tooth after a root canal. This will help protect the tooth, alleviate pain, and prevent further complications. Make sure to discuss all your options with your dentist, including the possibility of a crown, to ensure the best outcome for your dental health. Regular follow-ups and maintaining good oral hygiene will also play a significant role in the longevity of your dental work.
