One for dentists - Getting rid of tonsilloliths?

I have frequent bouts of tonsilloliths - that squishy, stinky bacteria that grows in the crypts of your gums. Though they are not painful or dangerous I am acutely aware of them and try to squeeze them out at every opportunity, but they keep re-appearing. They are a recent discovery and it bothers me knowing they are there. I brush twice a day and keep good oral hygiene - is there anything I can do to prevent these tonsil stones from returning?
