This is a high-risk but manageable case
.
Permanent nerve damage is rare (usually <1–2%), but temporary numbness/tingling can occur more commonly in such close-contact cases.
If the tooth is causing pain, infection, decay, or damage to adjacent tooth, removal is necessary & if its completely asymptomatic (no pain or infection or swelling) then wait and watch, no need for extraction
Next Steps
1. Consult an experienced Oral & Maxillofacial Surgeon (OMFS) only
2. Discuss option of coronectomy (removing crown, leaving roots)
3. Remove only if there is clear indication of pain, caries, swelling or damage to 2nd last tooth - 2nd molar).
Health Tips
1. Temporary numbness can take weeks to months to recover if it occurs.
2. Avoid unnecessary removal if completely symptom free.
