Hello, Thanks for using healthcaremagic. I understand your concern and like to tell you that yes neuropahy in late stage or when hereditory can affect the teeth pain. It can be treated with same medication which are used for peripheral neuropathy. The commonly used medication for this are gabapentin, pregabalin among others. I can not understand what do you mean by suicide disease. If you mean to say that whether suicidal ideation occur in this, I have coontrary evidence. Suicidal ideation can occur in any disease when the pain is unbearable. If that is the case please see a psychiatrist along with your other treating doctors to rule out depression. Thanks and regards
