Being treated by chiropractor for tmj by pushing on pressure points in/outside my mouth+activator, is this safe during pregnancy (6-8 weeks pregnant)?

No: The anatomy of the temporomandibular joints is not such that any "manipulation" will help. It could actually hurt. You need to unload your joints with a full coverage splint with even contact of all of the teeth to prevent teeth from moving while the spint is worn. Pregnancy is irrelevant. I suggest you see an orthodontist certified by the american board of orthodontists (abo).

Can't tell, but prob: I'm not familiar with "activator", and i'm very familiar with various TMJ treatments, so i can't tell what you mean by that. However, applying pressure to your face or mouth should not affect your pregnancy. At least, not to my knowledge. If the "activator" is a drug, then that's a different story. Find out from your chiropractor exactly what "activator" is, and tell your doctor that you're pregna.

Not really: There is no danger to your baby with this treatment, but have seen far better success with TMJ treatment from a specialized dentist who deals with TMJ issues. Get an appointment and consider a dental splint.

Probably safe, but: Probably safe, but more likely successful treatment with a TMJ 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.

Not recommended: There is insufficient scientific evidence of safety and/or efficacy of the various chiropractic treatment methods recommended for treating TMJ. See an Orofacial Pain specialist for the evidence based medicine, conservative treatment. Best of luck!
