Excruciating pain in my teeth on the top right of my mouth and bottom right only. it happens randomly most at night. is it sinus or ? 5+ teeth hurt.

Most likely not: It is very difficult to diagnose without a clinical exam. If your mouth is cavity free than a differential diagnosis would be tmd - temporal mandibular disorder or erupting wisdom teeth. You need to see a dentist for proper diagnosis and treatment.

Tooth pain: It sounds like it could be related to your sinuses- one way to test is to take an antihistamine (over the counter ) like benadyl and if it feels better - check with your physician for your sinuses. If not check with your dentist- you may be grinding your teeth and that can cause multple teeth to hurt.

Wisdom teeth?: That sounds like you are having infected or inflamed upper or lower right side or both. A visit to the dentist would reveal the reason and treat or suggest treatment..

Sinus, TMD, bruxing: You may have impacted wisdom teeth causing the pain. Sinus pain can hurt the teeth. Tmd can hurt like this. An exam with a differential diagnosis is needed from a dentist

Excruciating pain ?: Many possibilities. A severe infection can radiate ; refer pain making it seem like it was coming from more that one tooth. Same with the nerve of a tooth going non-vital. Sinusitis, tmjoint pain, pain from bruxism are other possibilities but less likely to cause "excruciating" pain. You may also have more than one dental problem. Want to know what the problem is and how to correct? See dentist!

Multiple possibilty: I'd start with your dentist. If negative, see a TMJ-orofacial pain specialist. Any dentist can be a TMJ expert with the proper training and experience. Most commonly, oral surgeons, prosthodontists, and orofacial pain specialists. Ask your MD, your dentist and your dental society for referrals.
