Thank you for the query.
Shingles on the gums can lead to formation of blisters with severe pain
, but according to the history given you are suffering from trigeminal neuralgia
. Anti convulsants have many side effects which you have been experiencing already . I would advise you to see your dentist
for the pain so that a clinical examination will reveal the exact cause for the pain . Yes, sometimes you are prone to have shingles of the gums which is a viral infection caused by herpes zoster
because of poor oral hygiene
as you become sensitive to touch or brush your teeth.
Hope this information helps you.
