For the last couple years I have been using an inexpensive athletic mouth guard ($1.99) to place some French Green Clay over my primary cavitation site. I then wear the mouth guard overnight. I have found that doing this definitely reduces the discomfort I am experiencing from the cavitations but it doesn't seem to make any real progress in actually eliminating the cavitation infection.
When I stop doing this the pain from the cav site increases again...and then once again subsides when I start doing this again; so I have reached a high level of certainty in knowing that the clay does have an effect on the cavitation.
