Root Canal Retreatment in Chișinău

We carry out root canal retreatment when a tooth has already had endodontic treatment, but pain, discomfort or signs of inflammation have appeared over time.

Repeat root canal treatment gives access to the canal system again, so that we can remove the old filling material, clean and disinfect the canals and then fill them with a tight seal.

The aim is to remove the source of infection and, wherever possible, keep your own tooth without extracting it.

When you may need root canal retreatment

The tooth was treated before, but pain or discomfort has appeared.

A swelling or a "pimple" appears on the gum near the tooth.

It hurts when you bite, although the tooth looks "normal".

The pain may go away for months and then return.

You get periodic pressure or a dull ache with no obvious cause.

A doctor once said that the canals were "complicated", but the problem has not gone away.

In most such cases the inflammation has remained, or has returned, inside the canal.

Why the problem can return after root canal treatment

Renewed inflammation does not mean that the tooth is hopeless.

Most often the causes are these:

the canal was not cleaned along its whole length
one of the canals was missed
the filling was not tightly sealed
bacteria were left in the canal
a crack or micro-leakage (tiny gaps that let bacteria in) appeared under the filling or crown
over time the restoration of the tooth lost its seal

In these situations retreatment lets the doctor treat the canal system again and remove the identified cause of the inflammation, provided the tooth has a good chance of being saved.

How retreatment is carried out

Examination and diagnosis

The doctor analyses the X-ray and assesses the condition of the canals, the filling and the tissues at the root. We explain why the problem has appeared and whether retreatment makes sense.

Anaesthesia

The procedure is done under local anaesthesia. There is no pain, even if the tooth was sensitive.

Removing the old filling

The old filling material is carefully removed to give access to the full length of the canal.

Repeat cleaning and disinfection

The canals are located again, cleaned of remaining infection and treated with medication. If an additional canal is found, it is treated as well.

Tight filling

After thorough cleaning, the canals are closed tightly again, so that the inflammation does not return.

Restoring the tooth

The doctor explains how best to restore the tooth, with a filling or a crown, so that the result is stable.

How long repeat root canal treatment takes

Retreatment usually takes 1 to 2 visits.
In complex cases an additional stage of medication may be needed.

The doctor gives the exact number of visits after diagnosis.

What happens if you do not have retreatment

The infection gradually destroys the bone at the root.

The pain may go away, but the process continues.

There is a risk of an abscess or a cyst.

The tooth becomes loose or unsuitable for saving.

In the end the tooth has to be extracted.

Retreatment is a chance to stop the process before irreversible consequences.

Frequently asked questions

Is retreatment painful?

No. The procedure is done under anaesthesia. After treatment you may feel discomfort when biting, which is normal and temporary.

Does retreatment always help?

In most cases, yes. But everything depends on the condition of the tooth and the tissues around the root. That is why the decision is made only after diagnosis.
