Root canal treatment cleans and seals the inside of a tooth under magnification of dozens of times, which raises the odds that you keep your natural tooth. Bident dentists in Chisinau use the dental microscope at every step, above all on molars and retreatment cases, where hidden canals stay invisible to the naked eye. A correct diagnosis starts with an exam, and your first consultation at Bident is free.
What Root Canal (Endodontic) Treatment Is
At the center of every tooth sits the pulp, a soft tissue with nerves and blood vessels that runs down through the root canals to the root tip. When deep decay, a crack, or an injury lets bacteria reach the pulp, the pulp inflames or gets infected. Pain sets in, and the infection can spread toward the bone around the root.
Endodontic treatment removes the diseased pulp, cleans and disinfects the canals, then fills them tightly. The goal stays clear: you clear the infection and keep the tooth in place instead of pulling it. A tooth treated well can work for many years. Our team treats the decay that started it all through our cavity treatment service, and once the pulp is already affected, we move to endodontics.
Why the Microscope Matters in Root Canal Treatment
Root canals run narrow, curved, and often branched. A molar has three or four main canals, plus side canals the naked eye never sees. If one canal stays uncleaned, bacteria linger and the treatment can fail months or years later.
The dental microscope magnifies the working field up to 25 times and lights it directly. That shifts the result in a few concrete ways:
- Real visibility: the dentist finds extra canals, unusual anatomy, and fine cracks that would otherwise slip past.
- Precise cleaning: shaping the canals stays controlled, without weakening the tooth walls for no reason.
- Better sealing: the dentist checks each step under magnification, which cuts the empty gaps where bacteria can settle back in.
- More predictable results on hard cases: molars, retreatments, and calcified canals gain the most.
Bident is one of the Chisinau clinics that works endodontics under the microscope for every patient who needs it, not only in special cases. You can see the equipment and the protocol on our endodontic treatment under microscope page.
The Steps of a Root Canal Under a Microscope
Every case differs, but treatment at Bident usually follows these steps:
- Diagnosis and plan. The dentist runs an exam, sensitivity tests, and an X-ray or, when needed, a three-dimensional CBCT scan to see the real anatomy of the roots.
- Local anesthesia. The area goes fully numb before we start, so discomfort stays minimal.
- Isolation with a dam. A rubber sheet isolates the tooth from the rest of the mouth. The field stays clean and dry, a factor that matters for success.
- Access to the pulp chamber. Under the microscope, the dentist opens the tooth with precision and locates the entrance of each canal.
- Measuring the canals. An apex locator, backed by an X-ray, sets the exact length of each canal down to the root tip.
- Cleaning and disinfecting. Fine instruments and antiseptic solutions remove the infected pulp and the bacteria across the whole canal system.
- Tight filling. The dentist fills the canals, as a rule with gutta-percha and bioceramic cement, so no space stays for bacteria.
- Rebuild. The tooth gets a composite filling and, often, a crown that guards it against fractures.
Depending on complexity, treatment wraps up in one or two visits. Retreatments and hard cases sometimes ask for more visits.
When You Need a Root Canal
Only a dentist sets the diagnosis after an exam and an X-ray, but a few signs often point to the need for endodontics:
- spontaneous pain or pain on biting that lingers;
- prolonged sensitivity to heat or cold that stays even after the stimulus goes away;
- deep decay that has reached close to the pulp;
- a crack or an injury to the tooth;
- swelling, an abscess, or a fistula on the gum near the root;
- a tooth that darkens with no obvious reason.
Sometimes the infection advances without pain, and the dentist finds it on a routine X-ray. That is why a regular check matters. If you feel any of these signs, book an exam early, because a tooth treated in time has a better chance of getting saved.
Root Canal Retreatment: When a Treated Canal Fails
A root canal can fail, even after years. The usual causes are a canal left uncleaned at the first intervention, a seal that has broken down, new decay under the crown, or a crack in the root. The signs of failure look like the first ones: pain, swelling, or a dark area at the root tip visible on an X-ray.
This is where the microscope matters most. In retreatment, the dentist removes the old filling, hunts for the missed canals, and cleans the whole system again, all under magnification. Many cases judged lost get solved this way with no extraction. When the tooth can no longer be saved, the dentist talks through the alternatives openly, including extraction and replacement with an implant. We do not promise a result before we see the real situation; we tell you honestly what odds your tooth has.
Does Treatment Under a Microscope Hurt or Take Longer?
Treatment happens under local anesthesia, so the procedure itself stays comfortable in most cases. Many people tie root canal treatment to pain, but that pain usually comes from the infection before treatment, not from the procedure that stops it.
The microscope does not stretch the session in any real way. It adds a few minutes of positioning, but it saves time through precision and cuts the risk of redoing the treatment later. After the intervention, mild sensitivity when you bite for a few days is normal, and common painkillers manage it. If the pain grows or swelling shows up, call us.
What Comes After Treatment: Filling or Crown
A tooth with no pulp no longer gets hydration from inside and turns more fragile over time. A correct rebuild protects it. For front teeth, a well-made composite filling is often enough. For molars and premolars, which take heavy forces when you chew, the dentist frequently recommends a crown.
A crown covers the tooth fully and prevents the fractures that could otherwise lead to losing it. At Bident we use metal-free zirconia crowns for a natural look and good strength. The dentist tells you at the exam whether you need a crown and when, based on how much healthy tissue is left.
How to Recognize an Infection After Root Canal Treatment
Mild sensitivity in the first days is normal. A few signs, though, call for a quick visit:
- pain that grows after the first week instead of easing;
- swelling of the gum or the cheek;
- a fistula, meaning a small bump on the gum that lets pus out;
- a lasting bad taste or fever.
These signs do not always mean the treatment failed. Sometimes the infection needs more time to pull back, other times the tooth asks for retreatment. Do not wait and do not self-medicate for long; the dentist finds the cause through an X-ray and decides the next steps safely.
Frequently Asked Questions About Endodontic Treatment
Is treatment under a microscope mandatory? Not in every case, but it raises precision and the success rate, above all on molars and retreatments, where hidden canals are hard to find otherwise. The dentist explains at the exam whether your situation calls for it.
Does the tooth stay “dead” after treatment? Once the pulp is removed, the tooth becomes non-vital, meaning it no longer has a nerve or vessels. It stays functional and can last many years, above all with a protective crown.
How much does a root canal cost in Chisinau? The cost depends on the number of canals, the difficulty (curves, calcifications), and the need for retreatment, so it varies from case to case. At the exam you get a clear treatment plan, with steps and an estimate, before we start.
Can an old treatment that hurts be redone? Yes. Endodontic retreatment under a microscope is common. The dentist cleans the old filling, hunts for the missed canals, and seals correctly, often with no need for extraction.
