Toothache that spreads to my head?

i have an on and off pain in my gum like 2 cm. above one of my teeth on the right side of my mouth that i can feel almost move up and to the back of my head and then moves to my brain behind my eye and then ends up in my nose near the bridge and goes away. this last like 10 minutes and is a sharp pain but it doesn't hurt like unbearably but it seems a little weird and i don't know what it is? Anyone know what it could be?
