Root Canal Re-Treatment in Frisco, TX

We do every other kind of root canal here. Root canal retreatment goes to a specialist, because a specialist gets a better result — not for convenience.

The process

What happens when a root canal tooth hurts again?

It is uncommon, and the tooth can often still be saved. The sequence below is what we actually do.

  1. We check whether that tooth is the cause

    Referred pain is common and the obvious suspect is not always the culprit. Testing, an X-ray and sometimes a CBCT establish whether the problem is the root-treated tooth, a crack, the gum around it, or a different tooth altogether.

  2. We work out why the tooth hurts

    A canal that was missed — some molars have an extra one that is genuinely hard to find. A canal that could not be fully cleaned. A fracture. Decay that has leaked in around the crown. Each of those has a different answer, and only some of them are re-treatment.

  3. We refer you to a specialist and explain why

    If it is re-treatment, you go to an endodontist. You will know why, what they are likely to do, and roughly what it will involve before you go. We explain it fully ourselves, beyond handing you a phone number.

  4. We stay involved after the referral

    The specialist re-treats. We look after the tooth afterwards — the crown, the bite, the follow-up. You do not become someone else's patient.

Good to know

Root canal retreatment: what to know first

Why a specialist, when we do every other root canal here

Because the second attempt is materially harder than the first. The old filling material has to be removed while protecting the root. The canal that was missed the first time has to be found, and it was missed because it is difficult to find. Fractures have to be identified before treatment, not after. Endodontists work under a microscope, do this every day, and have the ultrasonic instruments the work needs. We do all of our own primary root canals, molars included, precisely because we are confident in that work. This is a different procedure, and sending it out is a decision made for the outcome.

Re-treatment is not the only option

Depending on what is found, the answer may be re-treatment or a small surgical procedure at the root tip called an apicoectomy. Where the tooth is fractured through the root, the answer may instead be extraction and a plan to replace it. A root canal that has failed does not automatically mean a lost tooth. It also does not automatically mean the first treatment was done badly. Anatomy sometimes wins.

In depth

Why we refer root canal retreatment to a specialist

Most practice websites list what they offer and stop there. We think the referrals are just as informative, and in some ways more so.

We do every primary root canal here, molars included, when plenty of general practices send all of them away. And we send away the one procedure where a specialist genuinely gets a better result. Both of those are the same decision made on the same basis.

If a root-treated tooth has started bothering you, call (469) 262-2111 and we will find out what is actually going on before anybody refers you anywhere.

Cost & insurance

Root canal retreatment cost in Frisco: what to expect.

Billed by the specialistRe-treatment is charged separately by the endodontist. Their fee is generally higher than a first-time root canal because the work is harder.
The crown, separatelyThe tooth usually needs a new crown afterwards, and that part comes back to us.
InsuranceMost plans cover re-treatment, though some apply a time limit since the original treatment. We check yours before you go, so the specialist visit holds no surprises.

We receive nothing for referring you. The endodontist we suggest is the one we would send our own family to.

You get the figure in writing before treatment starts. We accept all major PPO plans and file the claim for you, our membership plan takes a percentage off treatment, and CareCredit financing is available.

Using your insurance

How plans usually cover retreatment.

Major — Class III on most plans

What plans pay
Commonly around 50% once the deductible is met, which means retreatment is the kind of treatment where the plan covers about half and the annual maximum decides the rest.
Deductible
Usually applies, and for major work it is rarely waived.

What catches people out

  • Waiting periods. Six or twelve months of holding the policy before major work is covered is common, and it catches people who have just changed employer.
  • The annual maximum. At around 50%, one major procedure can consume most of a $1,000 to $2,000 benefit by itself — which is why the order treatment is done in matters.
  • Frequency limits by tooth. "Once every five years" or "once every seven years" is standard wording, and it counts from the date of the last one wherever it was done.
  • Some plans will not pay to retreat a tooth within a set period of the original treatment, on the reasoning that the first course should have worked. Where that applies we tell you up front, before starting.

These are how dental plans usually classify this treatment — not a statement about your own plan. Yours is the one that governs, plans differ more than people expect, and the only reliable answer comes from reading your specific benefits, which we always do ahead of treatment and give you in writing.

And what changes out-of-network

A dentist who is in-network has signed a contract fixing what may be charged for each procedure and cannot bill you the difference. One who is out-of-network has signed nothing, so the full fee stands.

So the first difference is the price itself — the same treatment is simply allowed to cost more out-of-network, before anyone's plan is considered.

What you personally pay out of that depends on your own deductible and coinsurance, which is why there is no percentage here: it is not a property of the treatment, it is a property of your plan, and we verify yours before you commit. But two things follow for everybody. Your share is a share of a bigger number. And your annual maximum is spent by what the plan pays toward that bigger number, so the same treatment eats more of your benefit out-of-network.

An illustration, not a quote. These are the allowed fees for retreatment — taken from our own contracted schedules. An allowed fee is what the contract permits to be charged, in network and out. It is not what you pay: your deductible and your coinsurance decide that, and we work yours out in writing before you commit to anything.

Check the going rate yourself

FAIR Health's dental cost lookup is free, needs no account, and is not ours — it reports what a procedure typically costs in your area. It does not know your plan, so treat it as a ballpark figure — not a final answer.

Ask us for the number first

We verify your specific plan before your appointment and give you a written estimate: what the plan is expected to pay, and what you pay. If we get it wrong we tell you why.

Bring an Explanation of Benefits

Treated somewhere else? Your EOB shows exactly what the plan paid and what it counted against your maximum. Bring one in and we will read it with you — whether or not you become a patient here.

None of this says out-of-network dentists are worse dentists. Plenty are excellent, plenty are out-of-network for sound reasons, and people choose a dentist for who that person is. What we think you are owed is the information, so that whatever you choose, you chose it knowingly. The whole thing, explained properly, or call (469) 262-2111 and ask.

Root Canal Retreatment FAQs in Frisco, TX

Grouped so you can go straight to the one you came for.

Root Canal Re-Treatment — common questions

Do you do root canal retreatment in Frisco?
No. It is the only endodontic work we refer out. We do every primary root canal here, including molars. But a second attempt on a previously treated tooth is a materially harder procedure, and it belongs with an endodontist working under a microscope. That is a decision made for your outcome, not our schedule.
Why did my root canal fail?
Most often a canal that could not be found or fully cleaned the first time, since some molars have an extra canal that is hard to locate. Sometimes bacteria leak back in around a failed crown or filling margin, and sometimes the root has fractured. A failed root canal does not automatically mean the original treatment was poor.
How long after a root canal can it fail?
Months or many years. Some become symptomatic quickly. Others are found on a routine X-ray years later, as a dark area at the root tip in a tooth with no history of hurting. That is one of the reasons we take and compare X-rays over time, whether or not something aches.
Is re-treatment worth it, or should I just have the tooth out?
Usually worth it, if the tooth is otherwise sound and the root is not fractured. Your own tooth in your own bone is better than any replacement, and extraction plus an implant or bridge costs considerably more. Where the root is fractured, re-treatment cannot work and we will say so rather than let you spend money on it.
What is an apicoectomy?
A small surgical procedure at the tip of the root, done through the gum, where infection persists despite properly treated canals. The very end of the root and the infected tissue are removed and the root tip is sealed. A specialist does it, and it is an alternative to re-treatment, not a version of it.
Will you still look after the tooth afterwards?
Yes. The specialist does the re-treatment, and the crown, the bite and the follow-up come back to us. You are not being handed over. We are borrowing someone for one step. Call (469) 262-2111 and we will coordinate the referral and your follow-up visits with you.
What is the success rate of root canal retreatment?
It depends on the tooth, the cause of the problem and whether the root is fractured. Many re-treated teeth heal well, but a fractured root cannot be saved by re-treatment. An endodontist can give you an estimate for your own tooth after an examination. We will tell you early if we think your tooth is a poor candidate.
Can a regular dentist do a root canal retreatment?
A general dentist can examine the tooth and find the cause of the pain. We are general dentists, not endodontists, so we refer the retreatment itself to an endodontist, because a second attempt is harder and benefits from a microscope. We stay involved afterwards with the crown, the bite and follow-up.
Where can I get root canal retreatment near me in Frisco?
We assess the tooth at our office, 8175 Custer Rd, Suite A110, Frisco, and refer the retreatment itself to an endodontist. We then look after the crown and follow-up. Patients also come to us from Prosper, Plano and McKinney. Call to arrange an assessment and we will explain the referral first.
