Yes, it is possible there is outgassing of some compound from that bite device.

Seems there are endless poisons out there now.

Can we drink ANYthing bought in a grocery store safely? All come in plastic bottles.

Also the device may trap bacteria or viruses and hold them to the tissues, which normally would move the bacteria off. Mucus membranes need to breathe a certain way in order to work. Foreign bodies seem to generate disease. (remember toxic shock and certain types of tampons?)

The Doctors show on ABC just had a discussion last week on private female questions, and the OB/Gyn's had that advice and told it right on TV! Women should NOT wear underwear to bed! Should allow air to circulate "down there" to prevent infections!

The mouth is no different. Certainly a man made device in the mouth for HOURS was not what nature intended!
