Sometimes, tonsil stones can cause infection, and the infection can spread to the rest of your tonsil. Usually, symptoms of tonsil infection include ear pain, large tonsil stones, pain in your throat or tonsils, and difficulty breathing.
Ignoring tonsil stones and halitosis can have several potential complications. Untreated tonsil stones can lead to chronic bad breath, which can have a negative impact on social interactions and self-esteem. The persistent presence of tonsil stones can also contribute to recurrent infections in the throat and tonsils.

Tonsil stones (also called tonsilloliths) form when bacteria and mucus get trapped and calcify in your tonsils' nooks and crannies, leaving a hard piece of matter and a bad taste in your throat. See a picture of Tonsil Stones and learn more about the health topic.
If you’re wondering, “do braces cause bad breath,” we’re here to explain. Patients who wear fixed orthodontic appliances, such as braces, are at risk of developing bad breath due to the buildup of food particles on the teeth and poor dental hygiene. Therefore, it is crucial to maintain proper oral hygiene to prevent unpleasant mouth odors. Crooked teeth can cause bad breath as well—as it is more difficult to clean between the teeth. Alternatively, removable orthodontic appliances, such as aligners, may be a better option since they are easier to clean as they can be removed from the mouth.
