Is Swallowing a Tooth Dangerous?

Swallowing a tooth or a tooth fragment is not unusual. It can happen when your child's tooth is loose, during a sporting event or in an injury. Baby teeth, also called deciduous or primary teeth, are smooth and small enough for your child to swallow without realizing it. In a few cases, a swallowed tooth can be a legitimate concern for small children. When should you seek medical help?

Generally, a tooth is digestible. The National Health Service (NHS) reports that, “nearly all swallowed objects will pass through the digestive system without causing any harm, including those with sharp edges.” If an object can pass from the narrowest part of the digestive tract, from where the esophagus joins the stomach, it will most likely pass with no problem, notes the European Society of Gastrointestinal Endoscopy. However, it's always best to monitor your child for signs of problems and to seek your doctor's advice.

About 93 percent of swallowed foreign objects do enter your GI tract, reports the National Journal of Maxillofacial Surgery. But roughly 8 percent find their way into the tracheobronchial tree, or the airways that extend into your lungs. A foreign object within this tree is considered a medical emergency, reports the Royal Children's Hospital Melbourne. No matter the pathway after ingestion, it's critical to seek medical attention if your child has any of the following symptoms:

• Trouble swallowing
• Neck or chest pain
• Recurring vomiting
• Blood present in vomit or stool
• Abdominal pain
• Fever or drooling

Additionally, foreign objects like a tooth may not show up right away on an X-ray, and your doctor may need to perform an endoscopy. If your doctor advises retrieval, today's advancements in endoscopic procedures and in anesthesia make the process a little less uncomfortable.
