Root canal treatment in Plano to save the tooth when it can be saved

Dr. Chiem explains a panoramic X-ray on the wall screen to a patient in the chair

If a tooth throbs at night or aches when you bite, the nerve inside may be inflamed or infected, and a root canal can usually save it. Your first visit is an exam and an X‑ray you see on the screen, with every option explained in plain words. You leave with a written, itemized quote for the root canal and the crown. Nothing starts until you say yes.

If a tooth is throbbing

Does the tooth throb at night, and does the word root canal scare you?

Most people who ask about root canals are really asking one thing: will it hurt. The tooth is numbed before anything starts, and we check that it is fully numb before we begin. Most patients say it felt like a long filling.

The pain that sends people to us is usually the infection itself. Removing the inflamed tissue is what typically ends that ache, so many people feel better within a few days.

Your X‑rays go up on the screen beside the chair, and you decide from there.

  • “It wakes me up at night”A throbbing ache without a trigger often means the nerve is inflamed.
  • “I have been taking painkillers for a week”They mask the ache but do not reach the cause.
  • “Honestly, I am scared of the chair”Tell us when you call. We explain each step first and go at your pace.

The short answer

What is a root canal?

A root canal removes inflamed or infected pulp from inside a tooth, then cleans, disinfects, fills and seals the canals so the tooth can stay instead of being pulled. Most root canals here take one or two visits of about 60 to 90 minutes each. Most back teeth then need a crown, and with the in-office mill that crown is often made the same day.

Your first visitYou see the X‑ray on the screen and hear the plan before anything is decided.

Do you need a root canal? The signs to watch for

Only an exam and imaging can say for sure.

You may need a root canal if

  • A toothache wakes you at night, throbs without a trigger, or lingers after something hot or cold.
  • Biting or tapping on the tooth hurts, or the gum near it is swollen, tender or has a small pimple-like bump.
  • A tooth has darkened, or a deep cavity, a crack or a large old filling sits close to the nerve. Sometimes there is no pain, and an X‑ray shows a dark spot at the root.

What happens at your first visit

  • An exam, a cold test and an X‑ray, shown on the screen
  • A low-radiation 3D scan when the canals look complex
  • Every option explained, including extraction and waiting
  • A written, itemized quote for the root canal and the crown

What changes once the tooth is treated?

Results vary from tooth to tooth. This is what most people notice once the tooth is treated.

  • 01

    The ache ends

    Removing the inflamed tissue removes the source.

  • 02

    Your own tooth stays

    Roots and all, so nothing has to be replaced.

  • 03

    The infection is cleared

    The canals are cleaned, disinfected and sealed.

  • 04

    Protected the same day, often

    A crown shields the tooth, often made here the same visit.

  • 05

    The bone stays put

    Keeping the root keeps the jaw working around it.

  • 06

    Often less than replacing it

    Saving a tooth usually costs less over time than replacing it.

Root canal or extraction: which is right for your tooth?

When a tooth is infected there are two real choices. Your X‑rays and how much healthy tooth is left decide.

At a glanceMost asked aboutRoot canal and crownOption 2Extraction and replacement
What happensPulp removed, canals sealed, crown on topThe tooth is removed; the gap is left open or filled later
Your natural toothKept, roots and allGone for good
VisitsUsually one or two, plus a crown often made the same dayUsually one for the extraction, more if you replace the tooth
HealingTender for a few days in most casesThe gum closes in one to two weeks; the bone takes months
What comes nextA crown protects the tooth from crackingAn implant, bridge or partial, or the neighbors drift

Step by step

What happens during a root canal?

Five stages across one to three visits, depending on the tooth and the infection.

  1. 01

    Exam and imaging

    Dr. Tam or Dr. Chiem examines the tooth, tests how it responds to cold and pressure, and takes X‑rays. For back teeth with curved or extra canals, a low-radiation cone-beam CT shows the canals in 3D.

  2. 02

    Numbing and isolation

    The area is numbed, and we check that it is fully numb before we begin. A thin rubber sheet called a dental dam keeps the tooth clean and dry. If you are anxious, tell us when you book and we will talk through your comfort options.

  3. 03

    Cleaning and shaping

    Through a small opening in the top of the tooth, the infected pulp is removed and each canal is cleaned, shaped and disinfected with very fine instruments.

  4. 04

    Sealing

    The canals are filled with a rubber-like material called gutta-percha and sealed, and a filling closes the opening. A badly infected tooth may be medicated between two visits so it can calm down first.

  5. 05

    The crown

    Most molars and premolars need a crown afterward, because a treated tooth can become brittle. With our in-office mill, that crown is often made and placed in the same appointment. See crowns and bridges.

Healing and aftercare

How do you care for a tooth after a root canal?

Most people are surprised by how ordinary it feels.

The front desk team greets a patient at Custerpoint Family Dental
  1. The first day

    Wait for the numbness to pass

    Do not eat until the numbness wears off, so you do not bite your cheek. Take over-the-counter pain relief as directed, and finish any antibiotic as prescribed.

  2. Until the crown is on

    Chew on the other side

    Avoid hard or sticky food on the tooth, brush gently around it, and keep the crown appointment, because an uncrowned molar can crack. If a temporary filling falls out, call us.

  3. The first week

    Call if anything changes

    Soreness usually fades within a few days. Call if swelling grows, a bump appears on the gum or pain gets worse after day three.

If anything feels wrong, call 972-265-9033 during office hours.

Cost

How much does a root canal cost in Plano?

It depends on which tooth it is and what it needs afterward, so we give you a number after the exam. A front tooth usually has one canal, while a molar can have three or four.

What moves the number

  • Which tooth it is, and how many canals it has
  • Whether a cone-beam CT scan is needed
  • Whether the tooth needs a post, a buildup and a crown
  • Whether an earlier root canal is being retreated

Good to knowMany PPO plans cover part of a root canal and the crown, up to your annual maximum.

Questions

Root canal questions Plano patients ask us

Have one we have not covered? Call 972-265-9033 during office hours and you will reach the front desk.

Dr. Chiem reviews a panoramic X-ray with a patient in the treatment room
Most patients say it feels much like having a filling, only longer. The tooth is fully numbed first, and we check the numbness before we begin, so you feel pressure and vibration rather than pain. Removing the infected tissue typically relieves the ache that brought you in. Expect some tenderness for a few days afterward, which over-the-counter pain relief usually handles.
About 60 to 90 minutes per visit for most teeth, sometimes longer for a molar with three or four canals. Many root canals are finished in one visit. A badly infected tooth may need a second visit so medication can work between appointments, and the crown that usually follows can often be made in the same visit. You get a timeline at your exam.
Usually, if the tooth can be saved. Keeping your natural tooth avoids the bone loss and drifting that follow a gap, and it is often less costly over time than extraction plus a replacement. When a tooth is cracked below the gum or too little healthy tooth is left, extraction may be the better call. Compare both on our tooth extractions page.
Most back teeth do. A molar or premolar that has had a root canal can become brittle, and a crown protects it from cracking under chewing forces. Front teeth take less load, so they sometimes need only a filling. With the in-office mill the crown is often done in the same visit, so the tooth is protected straight away. See crowns and bridges.
Most root canals are done right here by Dr. Tam or Dr. Chiem, on the same schedule as the rest of your care. If a tooth is unusually complex, we tell you before treatment, not partway through, and help you get to the right specialist with your images. With local anesthetic alone you can drive yourself home.
It depends on your plan. Many PPO plans cover part of root canal treatment and part of the crown that follows, up to your annual maximum. We check your benefits and file the claim before work begins, and your share is in the written quote. Any remaining balance can go on CareCredit in monthly payments, with approved credit. See insurance and financing.
