What do you do when your gums feel swollen and are bothering you?

I was advising people to take between 1 and 5 grams of vitamin c a day, but taking just one gram a day myself. Today I increased my intake to 2 grams. I will have to see if 2 grams a day helps. If not I might increase it to 3 grams soon. I doubt that I will go over 5 grams a day, except during short periods of acute illness. Two grams a day instead of just one might make enough of a difference though. I have been taking 30,000 units of vitamin A a day the past two days, but plan to scale this back down to 10,000 a day after a week or so(before this I wasn't taking any fully formed vitamin A, just beta carotene.
Today I took 80 mg of zinc. I will cut this down to 50 mg or less a day within a week. Websites have recommended extra vitamin c, zinc, and CoQ10 for gum problems. I haven't taken any CoQ10 lately. Has anyone here gotten relief from gum pain or irritation from CoQ10? I guess I should get some and try it if it might help.
