Sometimes, a person may look at the tonsils and find that they have a white or yellow formation on the tonsil. It may be just sitting on the tonsil or it may appear to be inside the tonsil. These are commonly known as tonsil stones or tonsilloliths.
Information. Most people do not realize that they have tonsil stones unless they look in the mirror and see them. Some of them aren’t even easy to see and look like tiny grains of rice inside the tonsils. However, some people get them and they are the size of a large grape. Generally, tonsil stones do not cause any immediate health problems. Sometimes, they can grow to such a large size, then cause the tonsils to swell. Another issue is bad breath as tonsil stones have a very unpleasant odor.
