Ways to avoid the appearance of tonsil stones
1. Gargle with a mouthwash without alcohol.
Mouthwashes that contain alcohol can lead to dry mouth, which increases the risk of bacteria and stones accumulating in the tonsils. Opt for a brand that does not have alcohol and use it at least once a day. Alternatively, gargle with a salt and hot water rinse.
Gargling with salt water can also alleviate any discomfort caused by tonsillitis or infection of the tonsils, which can accompany the stones in the tonsils.
2. Remove the stones in the tonsils using a cotton swab.
If you notice stones in the tonsils in formation, remove them to avoid becoming sources of greater discomfort, bad breath or any infection. Moisten both ends of a cotton swab and gently massage your tonsils to release the stones. Gargle later to eliminate any remaining particles.
If you have a low pressure oral water irrigator, you can use it weekly to wash away any particles that get trapped in the folds of your tonsils.
3. Flosses at least once a day.
Flossing daily can prevent stones in the tonsils by eliminating the buildup of plaque and tartar. The stones in the tonsils are similar in composition and structure to the biofilms that form between the teeth. In addition, both can produce prolonged bad breath.  So, if you try to prevent stones in the tonsils to deal with bad breath, it is important that you eliminate that same biological matter in the place where it forms in your mouth.
4. Brush your teeth regularly.
Not maintaining good oral hygiene is a primary cause of tonsil stones. Brushing your teeth in the morning, before going to bed and after each meal is the basis of healthy oral hygiene habits and is the first step to prevent stones in the tonsils. This measure will help eliminate food particles and bacteria that can accumulate in the corners and cracks of the tonsils.
Remember to brush your tongue too, as it can harbor bacteria, mucus and food residues that may go unnoticed.
Extra Tips for You
When the stones appear, you can remove them by gently pressing them out with a toothpick coated with cotton, with the end of the toothbrush, or by washing them with a low pressure water irrigator. You can use that device, aiming the jet of water directly into the wells in order to thoroughly rinse the debris trapped there.
Good oral hygiene can completely prevent the appearance of tonsil stones. Brush your teeth after all meals, when you go to bed and when you wake up in the morning. When brushing your teeth, also gently brush your tongue and floss daily. Similarly, regularly use mouth rinses that do not contain alcohol. These techniques can reduce the amount of bacteria in the mouth, which can contribute to the development of tonsil stones.
