Hello,
I understand you have had pins and needles sensations around the lower left or right wisdom teeth area since an operation more than one year ago.
I feel sorry to hear that you have symptom of damaged nerves but it happens sometimes.
There are a few treatment options for numbness after wisdom tooth treatment including nerve regeneration surgery or nerve stimulation by laser or medications, or both combined together.
If you have already got numbness for more than 1 year then it is advised to see an oral surgeon to get an accurate examination.
Warm regards,
Ryan (Dr)
