I was told I had gum disease and would loose my teeth by an incredibly awful dentist. This resulted in panic and my having pain in all my teeth like burning in the gums and worse in two teeth, after countless visits and eventually a referral to specialist there was nothing wrong with me, I had got the gum thing under control and the rest was 'in my head' so to speak, once I was told this it lessoned. Now still comes on when I am stressed but I know its nothing to worry about so I can make it go much easier.
Not saying this is happening to you by any means, just letting you know what happened to me.
just saw your last sentance, I was fine till this too - I was 45 at the time and I now believe just starting peri.
