Thank you so much for your advice. I had some food
lodged in between my tooth and
a crown. This happened on Friday, October 28th. This has happened before and, normally, any food would've ejected itself overnight but, this time, it took 2 days too many so I was getting concerned because the pain was getting intense.
I found this site this morning and started the warm salt water treatments to try to reduce the swelling and rubbed a couple of ice cubes over the area.
