Periodontitis. Its extremely common. It leads to premature teeth loss. Look it up and go see someone to get treated.
As far as I can tell I have no symptoms of this. Not yet anyway. Sounds horrible.
The pain comes from the few areas where my gums have receded and have revealed small areas of the root of certain teeth. When something touches that area – toothbrush, ice cream, cold drinks it is painful, literally like touching the nerve.
I certainly don’t have gingivitis, bleeding or sensitive gums etc.
Regardless, a dental appointment has been made this morning and I’ll be investing in an electric toothbrush. Thanks for the info folks.
