Why It's Needed

When the inside of a tooth is infected

A root canal becomes necessary when the soft tissue inside a tooth — the pulp — becomes infected or inflamed, usually from deep decay, a crack, or repeated dental procedures on the same tooth. Rather than extracting the tooth, root canal therapy removes the infected tissue and seals the tooth, allowing you to keep your natural tooth for years to come.

Signs You May Need One

Common symptoms

Persistent Pain

Ongoing pain, especially when biting down or applying pressure to the tooth.

Sensitivity That Lingers

Sharp sensitivity to hot or cold that doesn't fade quickly after the stimulus is removed.

Swelling or Discoloration

Swelling near the tooth or a tooth that's darkened compared to those around it.

What to Expect

A non-surgical intervention, step by step

1. Numbing

The area around the affected tooth is fully numbed before anything begins.

2. Removing the Infection

The infected or damaged pulp inside the tooth is carefully removed.

3. Cleaning & Sealing

The inside of the tooth is cleaned, disinfected, and sealed to protect against future infection.

When a Root Canal Isn't Enough

Apicoectomy (root-end surgery)

Occasionally, infection persists at the very tip of a tooth's root even after a root canal — sometimes months or years later. An apicoectomy is a minor surgical procedure that removes just the infected root tip and surrounding tissue, sealing it from the other end. It's a targeted way to save a tooth that's already had a root canal, rather than resorting to extraction.

Common Questions

Root Canal Therapy in Norwalk, CT FAQ

Do root canals hurt?

No, they do not hurt — modern root canal therapy is done under local anesthesia, and most patients report feeling significantly better afterward since the source of pain has been removed.

Will I need a crown afterward?

Often, yes — a root canal-treated tooth is more brittle, so a crown is commonly recommended to protect it long-term. Learn more about crowns.

Is it better than an extraction?

Whenever possible, saving your natural tooth is preferable to extraction and replacement — it preserves normal chewing function and avoids the cost of a replacement tooth.
