đŸŠ· Root Canal Treatment in 2025: Everything You Need to Know

If you’ve been told you need a root canal, you might feel nervous, but don’t worry. Thanks to modern dentistry, root canal treatments are now faster, more comfortable, and more effective than ever before.

In this article, we’ll explain what a root canal really involves, why it’s necessary, and what you can expect before, during, and after treatment.

What Is a Root Canal?

A root canal treatment is a dental procedure used to remove infection or damage from inside the tooth — specifically from the pulp, which contains nerves and blood vessels.

When this inner pulp becomes infected due to decay, trauma, or a deep crack, the only way to save the tooth is to remove the infected tissue, clean the inside, and seal it to prevent further damage.


When Is a Root Canal Needed?

Here are the most common signs you might need a root canal:

đŸŠ· Persistent tooth painđŸ„¶ Sensitivity to hot or cold that lingers🩠 Swelling or gum tenderness near the toothđŸ©ž Darkening or discoloration of the toothđŸ’„ A cracked or severely decayed tooth

If left untreated, the infection can spread — causing abscesses, bone loss, or even tooth loss.


What Happens During the Procedure?

Modern root canals are usually completed in one or two appointments, depending on the complexity. Here's what you can expect:

  1. Numbing the area with local anesthesia

  2. Creating a small opening to access the infected pulp

  3. Carefully removing the damaged tissue and disinfecting the root canals

  4. Filling and sealing the tooth to prevent reinfection

  5. A dental crown may be placed afterward for strength and protection

Thanks to 3D imaging, rotary instruments, and laser cleaning, today's root canals are more precise and much more comfortable than in the past.


Does It Hurt?

One of the biggest myths about root canals is that they’re painful. In reality, the pain you feel is usually from the infection — not the treatment. With modern techniques and anesthesia, most patients feel little to no discomfort during or after the procedure.
