Endodontics and devitalization are synonyms

Devitalization is painful
No.
According to a study published by the American Association of Endodontists, the fear comes more from what others tell us than from our own experience with the dentist. Decades ago, due to limited knowledge and technology, these treatments could indeed cause pain. Nowadays, it makes no sense to associate this type of treatment with pain. By combining the professional’s technical skill with modern equipment, endodontic treatment can be performed comfortably for the patient.
Devitalized teeth darken
No.
The darkening of teeth after devitalization is related to improper cleaning of the inside of the tooth. With the correct technique, the likelihood of tooth discoloration is almost nonexistent.
Devitalization requires several appointments
No.
This type of treatment can often be done in one or two appointments. After the treatment is completed, the tooth should be properly restored to prevent future complications.
Devitalization weakens teeth
No.
Some teeth need to be devitalized because they are already severely weakened. If the restorative treatment is not adequate, the tooth or the restoration may fracture.
It’s better to extract than to devitalize
No.
The best for your health is to preserve your natural teeth as much as possible, and sometimes devitalization is the last resort to keep them. When this is no longer possible, implants are the best substitute.

For all the reasons mentioned here, before making a decision about what to do when you need dental treatment, consult a specialist.
