Our tonsils are little gland like structures that are present at the rear portion of the throat. The tonsils help catch bacteria and viruses that are present in the mouth and hence prevent them from causing an infection. The mixture of mucous and bacteria that are trapped inside may sometimes concentrate, harden and calcify to form a tonsil stone.
A person who has this may experience certain symptoms such as bad breath, a sore throat, and visible lumpy white material present at the back of the throat. Bad breath can sometimes be caused due to the presence of certain chemical compounds such as sulfur compounds. If sulfur compounds are detected in a person's breath there may be a high chance that the individual has developed tonsil stones. In fact, about 70% of people with sulfur compounds present in their breath have it. Sulfur compounds are one of the key symptoms.
An individual may also experience symptoms such as a sore feeling in their throat that may be caused due tonsilloliths. However a sore throat does not necessarily indicate tonsilloliths as it could even result due to a tonsillitis infection.
Other symptoms such as lumpy stuff which is white in color may be seen as well. Tonsilloliths are usually not visible and are covered within the tonsils. To see them when they are hidden within the tonsils one would need to have a special scan done such as a ct scan or an MRI scan to see where the tonsils are and how big they are.
One may also experience symptoms such as an inflammation of their tonsils. Although they are present in the throat, one may even experience pain in the ears due to the interconnected nerval pathways.
