According to WebMD, tonsil stones that cause no symptoms typically go away on their own. Tonsil stones that are a nuisance can be removed at home with picks or swabs. A regular salt-water gargle can also be helpful in easing the discomfort caused when tonsil stones are present.
In some cases, antibiotics are used with some effect in removing tonsil stones, but they do no treat the cause, according to WebMD. Large and hardened tonsil stones, which are rare, can be removed through surgery or in a doctor's office using a local numbing agent. Because tonsil stones are most common in people who suffer from chronic tonsillitis, a tonsillectomy, or the removal of the tonsils, may be necessary to prevent tonsil stones from occurring. Once the tonsils are removed, there is no risk for tonsil stones forming. This surgery is performed using general anesthesia and requires that a patient rest for several days after the procedure.
There is no preventative action that can be taken to stop tonsil stones from forming, according to WebMD. Caused by bacteria, dead cells and mucus being trapped in the tonsils, the stones become concentrated and then hardened. Tonsil stones can cause bad breath, a sore throat and white debris in the back of the throat.
