I floss every day and brush at least twice a day, I'm serious about dental hygiene because I know I have weak teeth. But last night while flossing I had an intense pain in my gum that shot up to my tear duct - made my eye water. There was no blood, redness or swelling. This morning I was brushing and the same pain was there. Still no noticeable redness or swelling. Then mid-day I went to floss and the same pain was there, very intense but only when the floss or toothbrush hits. I can still eat on that side. Now it being 24 hours, if I press really hard with my tongue right between the two teeth there's pain but still no redness or swelling. What's going on?
