May I know who can I go to confirm that I'm having trigeminal neuralgia?

I'm 30 yr old female and I have this pain on my right side of my jaw/ gum area.
I went to the dentist countless times but he said nth is wrong with my gum or my root. He think my pain is very vague and don't blif that I'm suffering.
I went to GP, he prescribed some antibiotics which are not easing my pain at all.
I wish to go to a specialist to confirm if i am really having TN.

I do not want to keep taking antibiotic and suffering here. The pain started 2 yrs back and it comes and go.
It stopped for abt 4 mth this yr and it came back attacking me (unbearable pain anymore).

I have this sharp pain on my right face area whenever I talk, brush teeth, gargle, drink water and eat. I'm suffering and I need help from a true professional.
     

so difficult to get a doctor who truly listen to ur pain.
