Repeated Repair: Why Do I Need a Second Root Canal?

If you ever had a severely decayed or damaged tooth, it’s likely that your dentist performed a root canal to repair and restore it. Although in most cases this procedure only needs to be completed one time, in some cases you may need to have it repeated. If you’ve found out you need a second root canal on the same tooth, it’s natural to wonder whether the treatment is truly necessary. Keep reading to learn more about why this happens so you can set your mind at ease!

What is a Root Canal?

To explain why you need another root canal, it helps to first establish what’s involved in the process. During this procedure, your dentist first numbs the area and then makes a small opening in your injured tooth so that they can clean it out using specially designed instruments. They’ll remove any unhealthy materials from the pulp of your tooth and then disinfect it. Finally, they’ll seal the hole and provide an appropriate restoration to shield it from future harm while simultaneously restoring its functionality.

Why Does My Root Canal Need to Be Redone?

Root canals are not uncommon, but they’re a surgical procedure like any other that comes with certain risks. It might become infected and not heal properly, for example. It’s also possible for a different issue to affect your now-vulnerable tooth later, even after you’ve recovered. Some possible causes that might lead to a repeat treatment can include:

• Hidden bacteria. Some teeth have narrow or curved canals where bacteria thrive and are difficult to access. It’s possible some of the germs were left behind during the first procedure and caused another infection.
• Additional decay. It’s possible for new decay to form near the already-treated tooth. It can enter the root canal filling which causes the initial issue to reoccur. The structure is already impaired meaning microbes can penetrate through the cracks.
• Delayed crown placement. If there was a prolonged period between when the root canal was completed and when your final restoration was placed, harmful bacteria would have plenty of opportunity to enter your vulnerable pearly white.  
• Cracked restoration. If your dental crown chips or fractures, then your tooth is no longer sufficiently protected and can develop disease or decay.
• Salivary contamination. Your saliva is full of germs and if your tooth wasn’t sealed properly, there’s a chance it caused a problem.  

If you’re not sure why you need a second procedure, feel free to ask your dentist. They can share detailed information about your oral condition so that you can understand their reasoning. Soon, the process will be complete, and you’ll once again have a happy, healthy smile!
