I had a root canal on the top in front with a temporary filling due to a bleaching process. I have not seen a dentist in about a year and there is an infection above the tooth and one of my eyes is swollen underneath.

I'd suggest you get in to see a dentist as soon as you can. You need an antibiotic to clear up the infection. A temporary filling is not meant to last a year. Temporary generally means a week or two.
