Our own Michael Plaut recently published a piece on temporomandibular disorders and sexual intimacy in the TMJA newsletter. Here's an excerpt:
A recent posting on the TMJA website included the following request: "I wonder if you could include something in a future newsletter about the romantic/sexual side effects of TMD which I feel aren't talked about much but are pretty relevant." (http://www.tmj.org/site/blogs/tmj-disorders/2013-08-14-1). She went on to describe some of her own experiences. The posting resulted in a number of responses expressing similar frustrations, relief that the issue was now out in the open, and that people had come up with some creative solutions.
TMJA President and Co-founder Terrie Cowley wrote an overview article about TMD in this newsletter in 1994, specifically referring to sexual effects. She wrote, "An inherent problem experienced by people with TMJ pain and dysfunction is the effect the illness has on the sex lives of the patient and partner. The once pleasurable sensations of being touched, hugged, kissed, having one's face stroked, and all the things that are an integral part of lovemaking and affection sharing, are now for many excruciatingly painful. Spouses frequently say they are hesitant to make sexual overtures for fear of physically hurting the sick partner or appearing insensitive to his or her pain."
