VISITS, MOST CASES

THE RELAPSE

When an old root canal speaks up.

A treated tooth should stay silent. Failure can surface months — or years — later, and it rarely announces itself politely.

✦ Pain returning in a previously treated tooth

✦ New swelling or a gum pimple near it

✦ Bite tenderness that never fully resolved

✦ A crown or filling that leaked, cracked, or came loose

✦ An infection spotted on a routine X-ray — no symptoms at all

✦ The treated tooth slowly darkening

WHAT ACTUALLY HAPPENS

Undone, then done right.

THE SECOND PASS

 FIG. 06 — WHY FIRST TREATMENTS FAIL THE ANATOMY, COMPLETED 

1

Find why it failed.

A CBCT scan before anything else: missed canals, leakage, new decay — and fractures ruled out, because retreating a cracked root helps no one.

2

Through the crown when possible.

A well-fitting crown can often stay. We access through it and restore the opening, saving you the cost of a new one.

3

Remove the old work.

Gutta-percha, posts, and carriers come out under the microscope — patiently, without sacrificing healthy tooth structure.

4

Find what was missed.

This is the heart of retreatment: locating the MB2, the calcified branch, the untreated inches — then cleaning them with GentleWave irrigation.

5

Seal it properly.

Warm vertical compaction fills the system in three dimensions. Then home to your dentist, with the recall schedule set.

CASE SELECTION

When retreatment is the wrong call.

A vertical root fracture, decay below the bone, or too little tooth left to restore — some teeth shouldn't be retreated, and pretending otherwise wastes your money and months.

When that's the finding, we say so at the consultation and lay out the real options: apicoectomy where the problem is surgical, or extraction and implant where it isn't. You get the assessment, not the automatic procedure.

NO BLAME

Why the first one failed.

Usually anatomy, not negligence. Canals hide — the MB2 in upper molars is missed in a large share of general-practice root canals because it's genuinely hard to find without a microscope.

We retreat other clinicians' work every week and our own standard is simple: find everything, seal everything, and prove it on the final image.

COMMON QUESTIONS

Asked in this chair, often.

Is retreatment worth it versus an implant?

When the tooth is structurally sound, usually yes — comparable long-term success, lower cost, faster timeline, and you keep your natural tooth and bone. When it isn’t sound, we’ll tell you.

Does the crown have to come off?

Not always. Many retreatments work through the existing crown; if it must be replaced, you’ll know before we begin.

How long does it take?

Usually one or two visits of 60–90 minutes, depending on what has to come out and what has to be found.

What does it cost?

Typically somewhat more than a first root canal because of the removal work — you’ll get an exact estimate at consultation, and most PPO insurance applies.
