1. How does a root canal work? ⇧

A root canal, commonly known as endodontic treatment, involves the removal of damaged or infected dental pulp. This soft tissue inside the tooth contains nerves and blood vessels and, when compromised, can cause significant discomfort and even lead to infections.

Before proceeding with this conservative treatment, our dentists conduct a thorough examination to determine its feasibility. The diagnosis may include X-rays to assess the tooth’s health and surrounding structures, internal condition, and the presence of deep cavities or fractures that may complicate or prevent root canal treatment. Not all teeth are suitable for root canal therapy—for instance, teeth with extensive damage or very advanced decay may not be treatable using this technique. Additionally, teeth that have undergone root canal therapy tend to be more fragile and prone to fractures. The decision to proceed must be made with care, taking into account the available therapeutic alternatives.

Key steps

At our clinic, we ensure a meticulous and minimally invasive procedure, performing root canal therapy by isolating the tooth with a rubber dam and proceeding with:

  1. anesthesia,
  2. tooth access,
  3. removal of the pulp,
  4. disinfection and filling of the root canal,
  5. sealing with biocompatible materials.

What happens after a root canal? You might experience slight sensitivity, which typically fades in the days following the treatment. Depending on the location and condition of the tooth, the dentist will decide whether a simple restoration is sufficient or if a protective crown is needed to strengthen it over time.

How long does a root canal take?

Let’s address the duration of the procedure, which is often a concern for our patients. A session can last from 30 to 90 minutes, depending on the specific condition of the patient, oral cavity, and tooth involved. How many sessions does it take? That depends on the complexity of the case, but generally, 1 to 3 sessions are needed.

2. How painful is a root canal? ⇧

Thanks to modern anesthesia techniques, discomfort is significantly reduced, and our patients report the procedure as very tolerable. If performed under local anesthesia, you won’t feel pain, though you may experience slight discomfort while chewing in the days that follow.

3. When is root canal treatment necessary? ⇧

Root canal treatment becomes essential when the pulp is infected or necrotic due to deep cavities, trauma, or dental fractures. Without timely intervention, serious complications such as dental abscesses or infection spreading to surrounding bone structures can occur. Typical symptoms that indicate the need for a root canal include:

  • sharp and persistent pain,
  • extreme sensitivity to hot or cold,
  • localized swelling or discoloration of the tooth,

presence of a gum fistula.

4. Root canal tooth: oral hygiene ⇧

Daily care of a root canal tooth is crucial to ensure its longevity and prevent further complications. Proper oral hygiene helps protect the remaining tooth structure and surrounding gums. Here are some tips for brushing your teeth safely with a root canal tooth:

  • use a soft-bristled toothbrush to avoid damaging the treated area, especially if a temporary crown is in place. Gentle, circular motions help clean effectively without excessive pressure;
  • choose a fluoride toothpaste to strengthen the enamel and protect the treated tooth from further decay. Fluoride helps fight bacteria and forms a protective barrier;
  • brush for at least two minutes, covering all surfaces—outer, inner, and chewing. Focus on the gumline and interdental spaces where food particles and plaque build up;
  • don’t neglect flossing, gently sliding the floss between teeth to remove plaque and debris your toothbrush may miss;

finish your routine with an antibacterial mouthwash to further reduce bacteria and add extra protection against infections.

5. When should a root canal tooth be extracted? ⇧

A treated tooth loses sensitivity but retains its function and appearance. In some cases, a crown may be necessary for added strength.

Extraction is only required in cases of severe fracture or a recurring infection that cannot be treated.

6. Safe root canal treatments ⇧
