Root canal treatment at 25×
Microscope-assisted root canal treatment
Root canal treatment saves a badly decayed, inflamed or injured tooth instead of removing it. The inflamed nerve and blood vessels inside the tooth are cleaned out, the canals are disinfected and sealed to the tip, and the tooth is rebuilt. At Harajda Dent the whole procedure is carried out under a dental microscope at 25× magnification.

The instrument
What we are looking through
The tooth being treated is examined at twenty-five times its size. That is what makes it possible to open canals invisible to the naked eye, to reach them through a smaller opening in the tooth, and to see changes inside it that neither the eye nor the X-ray picks up.

The difference in view
The same tooth at three magnifications
Most of a root canal happens in a space smaller than a grain of rice. These illustrations show why the level of magnification decides what can be found and treated.

What magnification changes about a root canal
The point of the equipment is not the equipment. It is that a tooth which would otherwise be treated partly by feel is treated by sight, and that changes what can be found inside it.
Canals that are otherwise invisible
At twenty-five times its size, canals open up that cannot be seen with the naked eye and in some cases cannot be seen on an X-ray either. A canal that is missed stays infected, and that is the most common reason a root canal fails. The same sharp view shows hairline cracks and decay creeping under an old filling while both are still small enough to treat gently.
Less healthy tooth removed
A smaller opening is enough to reach the canal when the view is magnified, so more of the sound tooth around it stays where it is. What is left of your tooth is what has to carry the repair for the next few decades.
A seal that runs to the root tip
Once the canal is clean it is filled along its full length with a material that seals tight against the canal wall. A root filling that stops short leaves space for bacteria, which is the failure this way of working exists to prevent.
A more predictable appointment
Working from what is visible rather than from what is expected makes the treatment safer, and usually quicker, because less is left to feel for.
If an earlier treatment failed
A tooth treated elsewhere that never settled can often be reopened, cleaned again and resealed. That is a different procedure from a first root canal, and the retreatment page covers what it involves.
Root canal treatment is usually needed when
- a tooth has become sensitive to hot or cold and stays sensitive after the stimulus is removed
- there is throbbing pain, or a tense, uncomfortable feeling when biting down
- decay has reached the pulp, the nerve and blood vessels inside the tooth
- a tooth was damaged in an accident, or the nerve was exposed while a filling was being prepared
- the nerve inside the tooth has died and an X-ray shows changes at the root tip
The appointment
How the treatment is carried out
The sequence below is the practice's own protocol for microscope-assisted endodontics. How many appointments it takes depends on the tooth: a single-canal incisor and a molar with four canals are not the same job, and we say which one you are looking at after the examination.
- 01
Examination and free assessment
The tooth is examined and the imaging your case needs is reviewed, so that the number of canals, their shape and any earlier treatment are known before anything begins.
- 02
Local anaesthetic
The tooth and the surrounding tissue are anaesthetised locally. Root canal treatment has a reputation built on how it was done decades ago; under proper anaesthesia the appointment itself should not be painful.
- 03
Isolating the tooth
The tooth is sealed off from the rest of the mouth with a dedicated isolation device, so that saliva and bacteria stay out of the area being treated. Keeping the canal clean while it is open matters as much as the mechanical work of cleaning it.
- 04
Access and locating the canals
A small opening is made in the tooth and the canals are located under the microscope. Because the view is magnified, that opening can be smaller than it would otherwise have to be, which leaves more of your tooth intact.
- 05
Measuring, cleaning, disinfecting
Each canal is measured to its full working length, then thoroughly cleaned and disinfected along its entire length, including the irregular anatomy that magnification makes visible.
- 06
Sealing to the root tip
The canals are filled all the way to the tip of the root with a material that seals tight against the canal wall, so bacteria cannot travel through them again. The opening made at the start is then closed with a filling.
- 07
Rebuilding the tooth
A root-treated tooth is no longer alive: it is weaker, it fractures more easily and it loses its natural colour over time. Depending on how much sound tooth is left, it is rebuilt with tooth-coloured filling material, with a post set into the root to carry the rebuild, or with a crown once the tooth has been free of symptoms for at least three months.
If a treated tooth does not settle, the first thing assessed is whether it can be reopened and treated again through the crown, without surgery, which is what the retreatment page covers. Where that is not possible, the root tip and the infected tissue around it can be removed surgically instead.
Microscope vs conventional
Two ways to treat the same tooth
Both approaches clean and seal the canals inside the root. The difference is how much of that system the dentist can actually see while doing it.
What guides the work
- Microscope-assisted
- The tooth at 25× magnification on a lit, sharp image
- Conventional, by eye
- What the naked eye and the X-ray allow
Hidden or unusual canals
- Microscope-assisted
- Can be located and opened
- Conventional, by eye
- Can be missed, the usual cause of a failed root canal
Access opening
- Microscope-assisted
- Smaller, because the canal can be reached through less tooth
- Conventional, by eye
- Larger, to give the eye a working view
Hairline cracks and early decay
- Microscope-assisted
- Visible while still small
- Conventional, by eye
- Often only found once they have spread
The final seal
- Microscope-assisted
- Checked by eye at 25× along the full working length of each canal
- Conventional, by eye
- Judged mainly from the X-ray taken afterwards
Working this way is the standard for every root canal at this practice, not an upgrade you are asked to choose between or pay extra for.
What it costs
What a root canal costs here
A root canal is priced per tooth, not per mouth, because that is what varies: a front tooth with one canal and a molar with four are different amounts of work.
What decides the figure
- Which tooth it is
- Incisors, premolars and molars have different numbers of canals and different anatomy to negotiate.
- How many appointments it takes
- Some teeth are cleaned and sealed in one visit. Where the inflammation needs it, the canal is dressed and reviewed before the final seal goes in, which means a second appointment.
- How the tooth is rebuilt afterwards
- A tooth-coloured build-up, a post set into the root, and a crown are separate steps with separate costs, decided by how much sound tooth is left.
- Imaging
- The diagnostic images your case needs are part of the plan you are quoted for.
How you get a price
- 01Free consultationThe practice's personal assessment costs nothing. We look at the tooth, review any imaging your case needs and explain what the options actually involve.
- 02A cost estimate before anything is scheduledYou are quoted for your own mouth, for the materials your case needs and the number of appointments it takes, rather than handed a table average that may not apply to you.
- 03You decide afterwardsThere is no obligation to book treatment after the consultation. If you are comparing clinics, take the estimate home with you.
Most of our patients travel from Austria and Germany. In the practice's experience, treatment here costs on average 15 to 20 percent less than comparable private care in Austria. Your own figure depends on your treatment plan, and you will have it in writing before anything is booked.
No prices are published on this site yet. Every figure you receive comes from your own examination, and nothing is charged for that examination.
Root canal treatment, answered
Does root canal treatment hurt?
The treatment is carried out under local anaesthetic, so the appointment itself should not be painful. The reputation root canals carry comes largely from how they were done decades ago. What usually hurts is the inflamed tooth before treatment. Some tenderness when biting for a few days afterwards is normal; tell us if it does not settle.
How many appointments does a root canal take?
It depends on the tooth and on what we find inside it. A single-canal front tooth and a molar with four canals are not comparable, and where the inflammation needs settling first, the canal is dressed and reviewed before it is sealed. We tell you how many visits your tooth needs after the free examination, before you commit to anything.
My root canal was done elsewhere and has not settled. Can it be redone?
Often, yes, but it is a different procedure from a first root canal. Reopening a treated tooth, clearing the old filling material and sealing it again is called retreatment, and it has its own page on this site with what it involves, what it costs and how healing is checked afterwards.
How long does a root-treated tooth last?
There is no single figure, because it depends on how well the canal system was cleaned and sealed and on what the tooth was rebuilt with afterwards. What shortens the life of a root-treated tooth most often is fracture rather than reinfection, which is why the restoration matters as much as the root filling. Keep it under review at your regular check-ups.
Will I need a crown after the root canal?
Sometimes. A root-treated tooth is no longer alive: it is weaker, it fractures more easily and it gradually loses its natural colour. If enough sound tooth remains, rebuilding it with tooth-coloured filling material can be enough; if not, a crown is fitted once the tooth has been free of symptoms for at least three months. You are told which applies to you as part of the treatment plan, since it changes both the appointments and the cost.
Is it worth travelling from Austria for a root canal?
Sopron is around 70 kilometres from Vienna, and the whole appointment can be handled in German. The reason patients travel here specifically is the microscope: if a tooth is worth saving, it is worth treating with the canals visible rather than felt for. Tell us you are travelling when you book, since a tooth that needs a second visit is better planned around your journey than squeezed into it.
