Root canal treatment with a microscope is today, in many cases, the alternative to extracting an inflamed tooth. The dental microscope magnifies and illuminates the treatment area so strongly that even the finest lateral canals become visible which remain hidden to the naked eye. This makes it possible to remove inflamed tissue completely, the tooth is stabilised from the inside and is preserved as the natural basis for chewing function and tooth alignment. At SP64 in Frankfurt’s Westend, microscope-assisted root canal treatment is part of the core of our tooth-preserving concept.
Many people still associate severe toothache or inflamed teeth with the fear that, in the end, the only option left is to have the tooth extracted. Yet it is exactly at this point that dentistry has developed decisively: today the focus is clearly on preserving the natural tooth, because it is and remains the most stable basis for a healthy dentition in the long term.
What makes root canal treatment with a microscope so precise?
A root canal treatment becomes necessary when the inside of a tooth becomes inflamed, for example as a result of deep caries or fine cracks. The aim is to remove the inflamed tissue completely and to stabilise the tooth from the inside for the long term.
A particular challenge lies in the complex structure of the root canal system. It is finely branched and different in every tooth. In addition to the main canals, there are often numerous tiny lateral canals in which bacteria can settle. Many of these structures are barely visible to the naked eye.
Better vision, better treatment results
This is where the dental microscope comes in. It magnifies the treatment area considerably and at the same time provides optimal illumination. As a result, even the smallest canals and hidden structures become visible.
Among other things, this makes the following possible:
- reliably locating all relevant canals
- the thorough and controlled removal of bacteria
- gentle handling of healthy tooth substance
Using the microscope therefore significantly increases the chances of success of the treatment and reduces the risk of renewed inflammation.
When can a tooth be preserved despite severe damage?
Today, many teeth can be preserved that would previously have been removed, even when the inflammation has already spread beyond the root tip into the bone. What is decisive is whether the bacterial cause in the root canal system can be specifically eliminated and whether the tooth can then be restored stably, for example with a filling, a ceramic inlay or a crown.
Whether it is a matter of severely inflamed tooth nerves, inflammation at the root tip or persistent discomfort after a previous root canal treatment: in many cases, root canal treatment with a microscope makes it possible to preserve the tooth. If the source of infection is removed completely and the canal is sealed tightly, the inflammation can heal and the tissue can regenerate.
For patients this brings clear advantages, as chewing function, load-bearing capacity and the natural tooth alignment are preserved. At the same time, more extensive restorations such as implants or bridges can often be avoided. Even so, the following applies: what is decisive is always an individual, realistic assessment. The focus is not on preserving the tooth at any price, but on the best long-term solution. If removal is necessary, SP64 offers high-quality, aesthetic restorations.
Give your tooth the chance to be preserved
Tooth preservation is no longer a matter of chance today, but the result of careful planning, modern technology and specialised expertise. At SP64, this is supported by the targeted use of a dental microscope and by clearly structured, comprehensible treatment steps.
Frequently asked questions about root canal treatment with a microscope
Is a root canal treatment painful?
The treatment is carried out under local anaesthetic and is experienced by most patients as easy to tolerate. The actual pain usually comes from the inflammation, not from the treatment. After the procedure, the tooth may react sensitively for a few days.
How long does a root canal treatment under the microscope take?
That depends on the number and shape of the root canals. Depending on the findings, one to two appointments are usual; a single appointment can take longer than a conventional treatment, because work under the microscope is particularly thorough.
When can a tooth no longer be saved?
If the tooth is deeply destroyed, severely loosened or the root is fractured lengthwise, preservation usually no longer makes sense. In these cases we discuss high-quality alternatives such as implants or bridges with you.
Give your teeth the best possible outlook: have the options in your situation clarified early, before removal even has to be considered. The team at SP64 in Frankfurt’s Westend will support you personally.
