Does having a post mean I need surgery?
No. The risks of removing it and the surgical alternative should be compared.
Before choosing treatment, start with what worries you
Cheonan root-end surgery (apicoectomy)Could surgery save the tooth—and why not treat it from the top again?
Being offered surgery for a root-treated tooth can sound more alarming than repeating treatment through the crown. You may worry about losing the tooth after enduring another procedure. Root-end surgery is one possible approach to a specific problem; it should be compared with nonsurgical retreatment and the condition of the whole tooth.
You can take time to understand your options before deciding.
01 / The questions behind the treatment name01 02 03
You deserve to understand what this means for your life.
Can the tooth still need extraction later?
Yes. Surgery cannot guarantee preservation in every case.
Will the crown also need attention?
Possibly, especially if leakage or structural damage is part of the problem.
02 / Benefits and burdens
Benefits and burdens
What may improve
Selected root-end problems can be approached while attempting to retain the tooth.
What to weigh up
Surgery, recovery and nearby-structure risks must be balanced against other options.
The question that helps you choose
Choose according to the source of disease, access and overall restorability.
03 / Make sense of your own situation01 02 03
What changes the choice of treatment?
Understand the reason for approaching the root tip
The assessment considers persistent disease, previous treatment and whether the canals can reasonably be accessed from above. A post or crown does not automatically make surgery the right choice. Ask what the surgical approach is intended to address and what information supports that decision.
Compare access risks and the ability to keep the tooth
Nonsurgical retreatment may involve removing a post or restoration, while surgery involves access through the tissues near the root end. Nearby anatomical structures, root shape, remaining support and restorability affect the balance. A crack or another unexpected finding may change what can be preserved.
Protect the result beyond the root end
A problem in the upper seal or crown may still need treatment. Fixing the root tip does not remove every source of reinfection. Discuss wound care, recovery and the timing of review imaging. Symptom relief and longer-term healing are different observations, so follow-up remains part of the plan.
Benefits and burdens
Potential benefits
A surgical approach may be considered when further access from above is difficult or unsuitable.
Examination of the root-end area can provide information relevant to the preservation decision.
Benefits and burdens
Limitations and risks
Persistent disease, structural findings or inadequate healing can limit success.
Pain, swelling and wound-care restrictions may affect the recovery period.
Treating a problem at the root tip
Root-end surgery may be considered when a problem at the root tip cannot be adequately managed through conventional canal access. Access, root-end treatment, sealing and follow-up have distinct roles.
- 01
Access the root end
After anaesthesia, the gum is opened to reach the affected root tip and nearby tissue, with access adapted to surrounding anatomy.
- 02
Treat the lesion and tip
Inflamed tissue is removed and the required root-end portion is resected to treat the lesion at the root tip.
- 03
Seal from the root end
A root-end cavity is prepared and filled to seal the canal from its apical end.
- 04
Close and review healing
The gum is repositioned and sutured. Wound recovery and symptoms are checked, while bone healing is assessed over time.

04 / Treatment and everyday life
Plan for the time between appointments, too.
Provide medication and medical history; do not stop prescribed medicines on your own.
Follow the wound-care instructions and return for planned healing reviews.
Costs, time and follow-up
Ask for a plan you can understand and manage.
What does the estimate include?
Ask which examinations, temporary stages, final treatment, retainers or maintenance, and repairs are included. The scope depends on your findings and chosen plan. A headline price cannot describe every person’s total cost. Ask how a change in the plan would be explained and agreed before it goes ahead.
Clinic fee information →How will visits fit into my life?
Bring previous records if you have them, your medication list and the practical limits on travel or time off work. Ask what each visit is for, what may change the timetable, and who to contact if something feels wrong. You do not need to promise to start treatment at the first conversation.
Location and visiting information →05 / Questions worth asking again
Uncertainty is a good reason to ask another question.
Is surgery always more definitive than retreatment?
No. The cause and access determine which option may be appropriate; a more invasive approach is not automatically better.
What if a fracture is found?
A fracture may alter whether the tooth can be retained. Discuss possible changes before consenting.
How will healing be checked?
Symptoms, examination and follow-up imaging may be used at an appropriate interval.
What happens if the tooth cannot be kept?
Discuss extraction and replacement alternatives in advance, including temporary arrangements.
Take these questions to your consultation
After your questions, meet the people you may speak with
Choose a conversation that addresses your concerns.
Read about the clinicians and their areas of practice. In your consultation, ask how the proposed plan answers your own priorities and what remains uncertain. This guide does not establish your diagnosis or promise an individual result.
