extreme gum sensitivity

a few other's have mentioned this...and i am having this pretty bad as well...

the pain is only in my receding gum area that i have become hyper sensitive all over, as before, i only had the receding gums but no pain.

i am curious if it is a healing effect going on? i have been told by dentists/specialists that i need skin grafting in order to repair my gums but i always refuse. i am hoping to heal the so-called irreversible damage to my gums with oil swishing...

anyhow, the sensitivity didn't start until Iodine supplementation. any thoughts?
