If you've undergone a root canal procedure, you probably know how crucial preserving and protecting your treated tooth is. Unfortunately, sometimes unforeseen circumstances can occur, and a root canal tooth becomes cracked. Let's discuss what may cause this, what to do about it, and your options.

Understanding Root Canal Treatment

Root canal therapy is used to preserve what remains of a severely damaged or infected tooth. This treatment treats the inner part of the tooth, the pulp chamber, which houses the tooth's nerve. A root canal is needed when the inner part of the tooth has been severely compromised.

During this treatment, the infected pulp is removed, and the inside of the tooth is disinfected. Afterward, the chamber is filled with a material to prevent further infection. The treated tooth is then usually crowned to restore its strength and functionality.

What happens when a root canal tooth cracks?

A crack in a tooth with a root canal can cause:

1. Pain and Sensitivity A cracked tooth can cause severe pain and heightened sensitivity, particularly when biting or chewing.

2. Reinfection: Cracks can create pathways for bacteria to enter the treated tooth, leading to reinfection of the root canal.

3. Compromised Restoration: If the tooth is crowned, a crack can undermine the crown's integrity, potentially leading to its failure.

4. Tooth Loss: In some cases, if the crack is severe and extends below the gum line, the tooth may become irreparable and require extraction. If this is the case, a bridge or dental implant may be recommended.

Common causes of a cracked tooth with a root canal

Several factors can contribute to the development of a crack in a tooth with a root canal:

1. Undetected Fractures: Sometimes, small cracks may exist in a tooth's structure even before the root canal treatment. These cracks may go unnoticed during the initial examination and worsen over time.

2. Trauma: Accidents or injuries to the mouth can cause a previously treated tooth to crack. Using your teeth to open things or biting on rigid objects just right can cause your teeth to crack.

3. Grinding and Clenching: Habitual teeth grinding or clenching (bruxism) can place excessive pressure on teeth, including those with root canals, leading to cracks.

4. Age and Wear: Over time, teeth can naturally weaken and become more susceptible to cracking, especially if they have large fillings or restorations.

Repair Options for a Cracked Tooth with a Root Canal

When faced with a cracked tooth, Dr. Maragliano-Muniz will assess the severity of the crack and recommend an appropriate treatment plan.

Common repair options include:

1. Dental Crown Replacement: If the crack is small and has not affected the root canal seal, replacing the dental crown may be sufficient to restore the tooth's functionality.

2. Root Canal Retreatment: If the crack has allowed bacteria to reinfect the treated tooth, a root canal retreatment may be necessary to remove the infection and reseal the canals.

3. Dental Bonding: In cases of minor cracks, dental bonding can fill and seal the crack.

4. Dental Implant or Bridge: If the tooth is severely cracked and cannot be saved, it may need an extraction and can be replaced with a dental implant or dental bridge.

Conclusion

If you have had a root canal procedure, caring for the treated tooth diligently is essential. However, even with the best care, cracks can sometimes occur. The longer a crack goes unaddressed, the more opportunity for infection to set in. Regular dental check-ups and open communication with your dentist are vital to maintaining the health and longevity of your dental restorations.
