Root canal treatment in Houston

If you've been told you need a root canal, take a breath — this is the treatment that stops tooth pain, not the one that causes it. At SoftDental, Dr. Nguyen saves your natural tooth gently and precisely, using a Leica surgical microscope and 3D imaging.

A toothache that won't quit, sensitivity that lingers long after something hot or cold, or swelling near a tooth — these can mean the soft tissue inside your tooth, called the pulp, has become infected. A root canal removes that infection, relieves the pain, and lets you keep your natural tooth. With today's tools, it's a routine, comfortable procedure.

Does a root canal really hurt?

This is the question almost everyone asks first — so let's answer it honestly and directly.

The old reputation

"Root canal" became shorthand for pain decades ago, when tools were simpler and the procedure took longer.

The reality today

A modern root canal is typically no more uncomfortable than a filling. The tooth is fully numbed, and the procedure relieves the pain you came in with.

What actually causes the pain is the infection — not the treatment

By the time a root canal is needed, the tooth already hurts. The procedure is what makes that pain stop. Dr. Nguyen uses a Leica surgical microscope to see the inside of the tooth in fine detail, which makes treatment more precise and more comfortable.

What a root canal treats

Inside every tooth is a soft core called the pulp, which holds the nerve and blood supply. When decay, a crack, or injury lets bacteria reach the pulp, it becomes infected and inflamed — and that's what causes the pain. A root canal cleans out that infected pulp.

Signs you may need one

Only an exam and X-ray can confirm it, but these are the common warning signs:

Lingering pain

A toothache that keeps coming back or won't fully go away.

Hot/cold sensitivity

Sensitivity that lingers long after the hot or cold is gone.

Swelling or tenderness

Swelling near a tooth, or pain when you bite down.

A deep crack or decay

A cracked or badly decayed tooth that's reached the nerve.

How the treatment works

Numb & access

We fully numb the tooth, then make a small opening to reach the infected pulp inside.

Clean & shape

Using the Leica microscope for a clear, magnified view, Dr. Nguyen removes the infection and gently cleans the inside of the tooth.

Seal

The cleaned space is filled and sealed to keep bacteria out, so the tooth can heal.

Protect with a crown

A treated tooth can become brittle, so we usually place a crown to protect it — often a same-day crown — so it's strong again.

Why patients choose SoftDental

Leica surgical microscope

High magnification helps Dr. Nguyen see fine detail inside the tooth for precise, gentle work.

3D CBCT imaging

Advanced imaging maps the tooth's roots and canals so nothing is missed.

Same-day crown option

We can protect your tooth quickly with an in-house crown, so you're not left waiting.

Root-end surgery

For the rare tooth that needs more, Dr. Nguyen also performs apicoectomy (root-end surgery) to save it.

Severe pain, swelling, or fever? Don't wait.

A dental infection can spread. Call us at 281-807-6111 — we keep room for same-day emergencies. If you have facial swelling that's spreading quickly, trouble breathing or swallowing, or a high fever, go to the nearest emergency room first.

Common questions

Is a root canal painful?
Modern root canals are typically no more uncomfortable than a filling. The tooth is fully numbed, and the procedure relieves the pain you arrived with. Dr. Nguyen uses a Leica surgical microscope and CBCT imaging for precise, comfortable treatment.
How do I know if I need a root canal?
Lingering pain, sensitivity to hot or cold that doesn't go away, swelling, tenderness when biting, or a deep crack can signal an infected nerve. An exam and X-ray confirm the diagnosis.
Do I need a crown after a root canal?
Usually yes. A treated tooth can become more brittle, so a crown protects it from fracture and restores normal chewing function. We can make a same-day crown so the tooth is protected quickly.
How long does a root canal take?
Many root canals are completed in one or two visits, depending on the tooth and the infection. We'll explain your timeline clearly at your appointment.
Why not just pull the tooth?
Keeping your natural tooth is almost always best for your bite, your other teeth, and your jawbone. A root canal saves the tooth, which is usually more comfortable and less costly over time than removing it and replacing it later.
