Beneath the surface.

Saving the tooth starts beneath the surface.

Natural teeth, preserved whenever possible.

Sometimes, the problem isn’t visible when you smile. A tooth can look almost completely normal while inflammation or infection is developing inside it. Inside every tooth is a living structure containing nerves and blood vessels. When this tissue becomes inflamed or infected, treatment may be necessary to prevent the problem from progressing.

01 — Our conviction

When a natural tooth can be preserved, we believe it deserves the opportunity.

You may notice:

Pain when bitingSensitivity to hot or coldA feeling of pressureDiscolourationOr sometimes, nothing at all
02 — The part of the tooth you cannot see

More than the mirror shows.

The visible part of a tooth is only one part of its structure. Beneath the enamel and dentine lies the pulp: the soft tissue containing nerves, blood vessels and connective tissue.

BeneathDentineThe layer between the enamel and the pulp.
InsidePulpNerves, blood vessels and connective tissue.
What can affect the pulp
Deep decayTraumaRepeated dental proceduresOther damage

If the inflammation or infection cannot resolve on its own, endodontic treatment may be recommended. The aim is to remove the affected tissue, carefully clean and disinfect the internal canal system, and seal the space to help prevent reinfection.

The work happens beneath the surface. The goal is visible every time you smile.

03 — When does a tooth need endodontic treatment?

Sometimes obvious. Sometimes not.

Endodontic problems can present themselves in different ways. You may experience:

01 / 06 · Persistent tooth pain

But symptoms are not always present. A tooth can have significant internal inflammation or infection without causing noticeable pain. That’s why diagnosis matters.

Seek urgent careFacial swelling, fever, difficulty swallowing or difficulty breathing requires urgent medical or dental attention.

Pain doesn’t always tell the whole story.

And no pain doesn’t always mean no problem.

Many people associate root canal treatment with severe toothache. But endodontic disease can develop gradually. In some situations, the nerve inside a tooth may lose vitality without producing significant symptoms. This is why a clinical examination and appropriate imaging can be important.

We don’t treat symptoms alone. We look for the reason behind them.

04 — The Smilea approach · Understanding

We examine the tooth and surrounding tissues, discuss your symptoms and, when appropriate, use dental imaging to assess the roots and surrounding bone. Is the pulp healthy, inflamed, infected or no longer vital? Can the tooth be predictably treated and preserved?

Diagnose
04 — The Smilea approach · Under local anesthesia

When root canal treatment is indicated, a small opening is made through the tooth to reach the internal canal system, preserving as much healthy tooth structure as possible.

Access
04 — The Smilea approach · The most precise stage

The infected or inflamed pulp tissue is removed. The root canals are carefully cleaned and disinfected to reduce bacteria and affected tissue within the complex internal anatomy of the tooth.

What cannot be seen still needs to be treated.

Clean
04 — The Smilea approach · Protection

Once adequately cleaned and shaped, the canals are filled and sealed with appropriate materials, to prevent bacteria from re-entering the canal system.

Seal
04 — The Smilea approach · Restoration

Root canal treatment is not the final chapter. The tooth may need a definitive restoration to protect what remains and restore function: a filling, onlay, crown or another solution.

Treat the inside. Protect the whole tooth.

Preserve
05 — Why preserve a natural tooth?

“What should replace the tooth?”

“Can we save it?”

Your natural tooth remains integrated with the surrounding tissues and continues to function as part of your existing bite. Extracting a tooth may create the need for replacement with an implant, bridge or removable prosthesis.

That does not mean every tooth should or can be saved. Some are too damaged, fractured or compromised to have a predictable prognosis.

Nothing is quite like your own tooth.

06 — Precision matters inside the tooth

In endodontics, millimetres matter.

  • Not straight tubesRoot canals can be narrow, curved and highly complex.
  • Multiple canalsSome teeth have several canals to locate and treat.
  • Hidden anatomySome anatomy is difficult to identify or access.

The goal is to locate, clean, shape and seal the relevant canal system as thoroughly as possible, with careful diagnosis, magnification and precise instrumentation where appropriate.

07 — Technology that helps us see more

When the problem is hidden, information matters.

Modern endodontics can use technology to improve diagnosis and treatment planning. Depending on your case, this may include:

A dental examination with a mirror and instrument
01Digital imaging

To evaluate the tooth and surrounding structures.

023D imaging

In selected cases, more information about complex anatomy, roots or surrounding bone.

03Magnification

With appropriate illumination, to help improve visibility during treatment.

04Modern instrumentation

Specialized instruments to assist in cleaning and shaping the canal system.

Technology does not replace the clinician. It gives a clearer view of what needs to be treated.

08 — Not the experience you fear

Comfort and control.

The idea of a root canal can make many patients anxious. Treatment is performed under local anesthesia, with the aim of keeping the procedure comfortable. The process is explained and your comfort is monitored. Reducing anxiety starts with understanding.

10 — What happens during a root canal?

A closer look at the journey.

The number of appointments and the overall treatment time depend on the complexity of the case.

Phase I · Stages 1–2

Understand

  1. 01Consultation

    Your symptoms and dental history are discussed and the tooth is examined.

  2. 02Diagnosis

    Clinical tests and appropriate imaging help determine the source of the problem.

  3. We look for the reason behind the symptoms.
Phase II · Stages 3–5

Treat

  1. 03Anesthesia

    Local anesthesia numbs the tooth and surrounding area.

  2. 04Access

    A small opening provides access to the internal canal system.

  3. 05Cleaning & shaping

    The affected pulp is removed and the canals carefully cleaned and shaped.

Phase III · Stage 6

Seal

  1. 06Sealing

    The canals are filled and sealed to reduce the risk of bacterial re-entry.

  2. Protecting the inside of the tooth.
Phase IV · Stage 7

Restore

  1. 07Restoration

    The tooth is restored to protect its structure and return it to function.

  2. Protecting the whole tooth.
Phase V · Stage 8

Monitor

  1. 08Follow-up

    Your tooth is monitored according to your individual needs.

  2. Regular dental care remains important.
11 — What happens after treatment?

Finished inside. Still needs care.

It is normal for a treated tooth to feel sensitive or tender for a short period. Your dentist will give instructions for your case. More importantly, the tooth usually needs a definitive restoration.

12 — Can a previously treated tooth need treatment again?

Sometimes, yes.

A tooth that has already undergone root canal treatment can occasionally develop a new problem or fail to heal as expected. Possible reasons include:

01Complex anatomy not fully treated
02Persistent or new infection
03Leakage around the restoration
04New decay
05Fracture
06Problems with the previous treatment

Depending on the situation, endodontic retreatment may be considered. In selected cases, another procedure such as apical surgery may also be discussed. The right solution depends on the reason for the problem and the long-term prognosis of the tooth.

13 — When saving the tooth isn’t possible

Preservation has limits.

A severe vertical root fracture, extensive structural damage, insufficient remaining tooth structure or other factors may make the prognosis unfavorable. Then extraction may be recommended, and the conversation continues: a dental implant, bridge or other restoration can be considered.

Not to save a tooth at any cost.

To choose the treatment with the best long-term outlook for you.

14 — Questions

Asked often.

Anything else on your mind? Your dentist will answer it during your consultation.

Q.01Is a root canal painful?+

Root canal treatment is performed under local anesthesia, with the aim of keeping the procedure comfortable. The tooth may feel sensitive or tender afterwards, particularly in the first few days. If you experience significant or persistent pain, contact your dental team.

Q.02Why do I need a root canal if my tooth doesn’t hurt?+

A tooth can sometimes develop pulp inflammation, infection or loss of vitality without causing significant symptoms. Dental examination and appropriate imaging can reveal problems that are not obvious from symptoms alone.

Q.03How long does a root canal take?+

Treatment time varies with the tooth and the complexity of its canal anatomy. Some cases can be completed in a single appointment, while more complex cases may require multiple visits. Your dentist can be more precise after evaluating your tooth.

Q.04Can every infected tooth be saved?+

No. It depends on factors such as the amount of remaining tooth structure, cracks or fractures, the condition of the surrounding tissues and the complexity of the infection. A proper diagnosis is necessary to assess the prognosis.

Q.05Do I need a crown after a root canal?+

Not necessarily in every case. The appropriate restoration depends on the tooth, how much structure remains and the forces it is exposed to. Some teeth may require a crown or onlay, while others may be restored differently. Your dentist will recommend the right option for your tooth.

Q.06How long does a root-treated tooth last?+

A successfully treated and properly restored tooth can function for many years. Its long-term prognosis depends on the quality of the endodontic treatment, the final restoration, oral hygiene, gum health, bite forces and whether new decay or fractures develop. Regular dental care remains important.

Q.07Can a root canal fail?+

Endodontic treatment has a high success rate, but no treatment is guaranteed to succeed in every case. Persistent infection, complex anatomy, leakage, fracture or other factors can affect the outcome. If a treated tooth develops problems, retreatment or another option may sometimes be possible.

Q.08Can an endodontic infection spread?+

An untreated dental infection can extend into surrounding tissues and, in some cases, cause swelling or more serious complications. Facial swelling, fever, difficulty swallowing or difficulty breathing requires urgent medical or dental attention.

Q.09How much does endodontic treatment cost in Brussels?+

The cost depends on the tooth being treated, the complexity of its root canal anatomy, whether previous treatment is present and the restoration required afterward. A personalized estimate can be provided after your tooth has been examined and the treatment plan established.
