I believe I have a canker sore on my gum. If so can they cause swollen lymph nodes underneath the mandible?

In brief: Canker sore

Yes they can cause temporary swelling of lymph nodes.
If nodes are tender and do not resolve then you should be checked by your doctor.

In brief: Canker sore

Any form of inflammation can produce enlarged and tender regional lymph nodes.
This does not guarantee that is what is happening to you, but it makes sense. You should of course be vigilant for other things like an infected tooth or gums. Good luck.
