Lymph nodes – please help

Patient: Are these lymph nodes normal?Hard but mobile lymph node just above clavicle, more toward my traps/neck though. Is this normal?Would rotten teeth on the same side cause this? I have several rotten teeth on the same side and a few other tiny lymph nodes enlarged on the neck.I also have previously had an ultrasound on my groin and a CBC as I had hard but mobile lymph nodes there aswell. The doc said everything came back clear.

Symptoms: No signs/symptoms of anything, just lymph nodes popping up.
