Do I have TMJ?

In general, your body does not like change. Although our bodies, especially our temporalmandibular joints, are quite adaptable, dyfunction and symptoms in these joints is common. The cause of symptoms, however, is extremely multifactorial. Tooth movement can exacerbate an underlying problem and bring about your TMJ symptoms. With all of your patients, regardless of treatment, we warn them that if they start developing TMJ symptoms, that treatment may need to be put on hold, and that they have to go through a separate phase of treatment, usually involving a splint, until their symptoms have alleviated. Then, they MAY by a candidate to finish treatment.

TMJ Dysfunction can result from  tooth movements if the TMJ's are not in a healthy functioning position to begin with.  This is what you are describing .  Otherwise the slight movement into tray 6 would not be enough to cause the problem.  Your dentist/orthodontist may not have picked this up in the evaluation.  Disucss your situation with them to come up with a solution.  Invisalign, or braces for that matter should not be used to treat TMJ Dysfunction if the dysfunction is present when starting treatment.
