How do I know if my root canal has failed?

The signs aren't always obvious, but common symptoms include:

Is it better to try retreatment first?

It depends on why it failed. If it’s a simple issue like a loose crown leaking bacteria, retreatment might work. However, if the root is cracked or the infection is severe, an implant is almost always the better investment. We will use a 3D CBCT scan to help you make the right choice.

Is the extraction of a root canal tooth painful?

No. Root canal teeth are often brittle, but we remove them very gently under local anesthesia. Most patients report that the relief from removing the chronic infection is immediate and far outweighs the mild post-extraction soreness.

How long do I have to wait for the implant?

If the infection is severe, we typically extract the tooth and place a bone graft, allowing the area to heal for 3-4 months to ensure the infection is completely gone before placing the implant. This ensures the highest success rate.

Can a Failed Root Canal Be Fixed with an Implant?

The Reality: While root canals are highly successful, they can fail due to complex anatomy, new decay, or cracks in the root.
The "Fix": A dental implant doesn't "fix" the root canal itself; it replaces the failing tooth entirely. This eliminates the source of infection permanently.
Why Choose an Implant? Unlike retreatment (doing the root canal again), which has a lower success rate, a dental implant offers a predictable, long-term solution with a 95%+ success rate.
The Process: We gently extract the failing tooth, often place a bone graft to preserve the foundation, and then place the implant.
The Takeaway: If your root canal has failed, you don't have to live with pain. An implant is a second chance at a healthy smile.

By Dr. Raheel Thobhani, DMD

You’ve already been through the procedure, paid for the crown, and thought your tooth was saved. So, when pain or swelling returns to a tooth that has had a root canal, it can be incredibly frustrating and discouraging. You might be asking, "What went wrong? And do I have to lose the tooth now?"

This is a common scenario we see at Smyrna Dental Studio. The question we often hear is, "Can a failed root canal be fixed with a dental implant?" The answer is yes. While an implant doesn't repair the old root canal, it replaces the troublesome tooth entirely, offering a permanent solution that stops the cycle of pain and infection once and for all.
