I have tonsillitis for the first time. with it, i just got a tonsil stone. does this mean that i will continuously get them, even once i'm better?

Not necessarily: Some infections may increase tonsil stones, but it is not inevitable. See this site for more information on this topic, including prevention. http://www.webmd.com/oral-health/guide/tonsil-stones-tonsilloliths-treatment-and-prevention.

No: You are not condemned to have chronic tonsillitis, but it may not be the last time you see a tonsil stone either.
