Can teething cause my child to get a runny nose, diarrhea or an ear infection?
Teething is often associated with these problems but as far as we know there is no direct correlation. Theoretically teething may lower your child’s resistance leaving them with more susceptibility to viral respiratory illnesses (“colds”) and viral gastroenteritis (Diarrhea). Also, when children have teething, they have swelling of their gums and this may lead to swelling and obstruction of their eustacian tube (the drainage canal fur the middle ear) and this could lead to an ear infection. If a child has a fever of 101 degrees or higher, there is always something else going on (i.e. infection) because teething does not cause temperatures to this level. So the answer to your question is that teething is associated with some of these problems but as far as we know does not directly cause then.
