Accidentally swallowing a tooth can be a surprising and concerning event. However, in most instances, this occurrence is not a serious medical emergency. The human body is capable of handling foreign objects in the digestive system, and a swallowed tooth typically passes through without causing health complications.
The Tooth’s Path Through the Body
When a tooth is swallowed, its journey begins in the esophagus, the tube connecting the throat to the stomach. The tooth then enters the stomach, continuing its transit through the digestive tract. Teeth, composed primarily of calcium, are not digestible by stomach acids, but their smooth, small size allows them to navigate the system.
From the stomach, the tooth moves into the small intestine and then the large intestine, following the natural flow of digestion. Most swallowed teeth pass through the digestive tract like regular food. This process typically takes 24 to 48 hours for the tooth to be expelled from the body through feces. Inducing vomiting or using laxatives is not advised, as the body’s natural processes are sufficient for passage.
When to Seek Medical Attention
While swallowing a tooth is often harmless, specific symptoms warrant immediate medical attention. These signs suggest a potential complication. If persistent pain, difficulty swallowing, or neck or chest discomfort arises, it could indicate the tooth is lodged in the upper digestive tract.
Other concerning symptoms include recurring vomiting, abdominal pain, fever, or blood in vomit or stool. A swallowed tooth, especially if it has sharp edges, could cause irritation or a tear in the digestive lining. In rare instances, a tooth might enter the airway, leading to breathing difficulties, which is a medical emergency.
Baby Teeth Versus Adult Teeth
The type of tooth swallowed can influence the likelihood of complications. Baby teeth, also known as deciduous teeth, are smaller and smoother than adult teeth. A key difference is that baby teeth undergo a natural process called root resorption, where their roots dissolve as permanent teeth develop and emerge. This makes them less likely to cause issues if swallowed.
In contrast, adult teeth are larger and have fully formed roots. While they usually pass without incident, a larger adult tooth might pose a slightly higher risk of discomfort or impaction compared to a baby tooth. Regardless of the tooth type, if any concerning symptoms develop after swallowing, seeking professional medical advice is recommended.
