The two problems do NOT sound to be related.
I would think that you most likely have a separate (sorry) issue goin on on the opposing side where you are having this new pain.
What would I do?
If possible, I'd get to a Dentist today!
If you can or can't, I'd make an ice pack using a ziploc bag with ice and water, wrapped in a small cloth and apply it to the pain area. The cloth buffers the extreme col. Also, take up to 800 mg. Ibuprofen (if you are over 18) every 8 hours for pain.
Again, call around, you hopefully can get into a Dentist, as you possibly may have an abscess beginning(?).
I hope you can get in today. Take pain medication, as needed. Ice packs help with pain too.
Let me know if I can assist further?
*please do rate my answer. I hope you get feeling better!
