Root Canal Treatment (Endodontics)

What complications can occur after endodontic treatment?

Root canal treatment is a commonly performed dental procedure, but some complications may occur.

Root canal treatment is a commonly performed dental procedure, but even so, some complications may occur.

Possible complications after endodontic treatment include:

  • Pain and swelling: After endodontic treatment, the tooth or surrounding tissue may be sensitive and cause pain and swelling. These symptoms usually subside within a few days and can be treated with pain medication.
  • Infection complications: Despite thorough disinfection of the root canals, infection may occur. If you experience pus, pain or fever, it is important to contact us as soon as possible.
  • Broken instruments: Special instruments are used during canal cleaning, and one of them may break. This can complicate treatment and require additional procedures. Therefore, we use microscopic endodontics to prevent such complications.
  • Loss of tooth structure: After endodontic treatment, it is usually necessary to restore the tooth with a dental crown. If this crown is damaged or falls out, further problems may arise. Always contact us in good time.
  • Numbness or discolouration of the tooth: In some teeth, the root canals may be irregularly shaped or very narrow, which can make it difficult to clean and seal them completely, increasing the risk of treatment failure.
  • Cracked tooth after endodontic treatment: If the tooth is severely damaged by inflammation, it sometimes cracks after cleaning and filling the canals. In this case, it is important to proceed with the next step – tooth extraction.

It is therefore essential to follow our instructions carefully, attend regular check-ups and respond promptly to any unusual symptoms or complications.

If necessary, it is possible to proceed with so-called re-endodontic treatment (re-endodontics), where the entire root canal cleaning procedure is performed again and the inside of the tooth is revised.

Do not wait until the condition of your tooth worsens.
