A retained root fragment after extraction does not always cause a future problem, especially if it is small, deeply embedded, and there is no infection or symptoms. However, an upper premolar root should not simply be assumed to be harmless because the fragment can occasionally cause infection, pain, or delayed healing.
Next Steps
* Have a dentist/oral surgeon take an IOPA X-ray to determine the size and exact position of the retained root.
* If it is small, deeply placed, and asymptomatic, the dentist may decide to leave it and monitor it.
* If it is mobile, infected, close to the sinus, or causing symptoms, surgical removal may be considered.
* Seek review sooner if there is increasing pain, swelling, pus, bad taste, fever, or delayed healing.
Health Tips
Don’t try to remove or disturb the root yourself. Keep the extraction site clean, follow the post-extraction instructions given by your dentist, and attend a follow-up examination/X-ray to confirm that healing is progressing normally.
