wish you could oil pull to get rid of cavitations but I don't believe you can. I have been oil pulling to keep from getting cavities though. That has been working quite well in removing tartar and plaque build-up on my teeth. Cavitations are located in the jaw bone, below the surface of the gum line in the pockets where teeth used to live before they were extracted. The only way I'm aware of to get rid of them is with surgery.
