The stone cold fact is that tonsil stones (aka tonsilloliths) have absolutely no connection to cancer, so you can (literally) swallow your fear. In fact, they are nothing more than calcified deposits of food debris caught in the crevices your tonsils, where bacteria, dead cells and mucous, can become trapped. They can also occur due to a build-up of minerals such as phosphorus and magnesium. And while they can begin to reek, resulting in bad breath, they are basically harmless, despite the fact that they commonly appear alongside bouts of tonsillitis (inflammation of the tonsils).
At the same time, tonsil stones can make it hard to swallow as well as cause ear pain due to shared nerve pathways, although the stones themselves are nowhere near the ears. In addition, swelling of the tonsils may also arise depending on their size. Still, most adults and children aren’t even aware that they have them until they show up in a CT scan or x-ray.
For the most part, tonsil stones are regularly dislodged during coughing and eating. However, there are times when they need to be manually removed. This can be done fairly easily using a salt-water gargle every day until they are discharged. In fact, gargling with salt water is also a good way to prevent them from forming in the first place since it serves to remove bacteria and disinfect the mouth before they form.
Similarly, using a tongue scraper to remove the active bacteria and brushing your teeth and tongue at least 2-times a day to get rid of any food debris that gets trapped in your mouth can help prevent tonsil stones. So can drinking plenty of water to prevent your mouth from getting too dry. Note, however, that drinking sweet drinks such as a soda can actually contribute to the development of the stones. You should also avoid a lot of dairy products, which reportedly encourage the build-up of calcium and mucus, which are known to cause tonsilloliths. Likewise, attempt to cut back on alcohol consumption and quit smoking.
In the meantime, you can try to remove your tonsil stones yourself by pressing on your tonsils and try to break up the stones or push them free with your tongue. You can also try using your finger or a wet cotton swab to dislodge them. This, however, is not as easy as it sounds and you will probably need the help of either a dentist or doctor, who may actually recommend using combination tonsil cryptanalysis, radio frequency signals to break them up. This is done under local anesthesia and is far less invasive than having to undergo a tonsillectomy (in extreme cases).
