What does “Pulp necrosis” mean?
Pulp necrosis is the death of the pulp tissue inside a tooth, which contains blood vessels and nerves. Deep decay or trauma may be involved, and absence of pain does not mean the pulp is healthy.
Can the pain disappear?
When nerve responses in the pulp are lost, pain previously triggered by cold may decrease. Inflammation around the root may later cause pain on chewing or swelling.
How is it diagnosed?
Responses to thermal and electrical stimuli, percussion, imaging, and history are considered together. A single absent response does not establish necrosis; other findings are compared.
How is the tooth treated?
If the tooth can be preserved, treatment to manage infection inside the root canals is considered. Other options may be needed if the remaining tooth, roots, or surrounding tissues are in poor condition.
Frequently Asked Questions
If the nerve has died, will the tooth fall out immediately?
The pulp and the tissues supporting the tooth are different. With appropriate treatment and restoration, a tooth can function even after its pulp has been removed.
Can I cancel my appointment now that the pain has gone?
Reduced pain alone does not establish healing. Previous pain and current examination findings are assessed to determine whether infection is present and treatment is needed.
