Can a bad tooth without pain make a lymph node in the neck swell?

Bad tooth or teeth have the capacity in the right circumstances to result in death. THey should never be ignored.

This is a question best addressed by your dentist, or doctor.

Yes but u should see a dentist

Understand that our lymph nodes swelling are a warning sign to our immune system that there is an infection somewhere in the body. I keep on telling people Lymph nodes are our first defence. Lymph nodes are located throughout our body. There is one under each ear. That is why it is swollen !

Now get yourself to a dentist !
