Hi Jess,
Be aware that any information from myself is purely based on many years of using Ionic silver.
It is usually about 10 PPM on a TDS meter. I have read that this is not a accurate reading either, but that's what I have.
Occasionally If I forget that I'm making CS it will get to 15 PPM if left for a longer time.
Anyway it works for whatever I have used it for, so I don't use anything else.
You can buy large particle silver [500, 1000PPM,etc.], and who knows if it would stain your teeth.
So the point is you didn't say what you're using.
Also about the only time I use it orally is to gargle with it if I feel a cold, or sore throat.
Tooth /gum pain
If this is persistant, it may be wise to see a holistic dentist to see what's going on.
You can just get an opinion, and suggested course of action.
Have amalgams, root canals?
No help, but maybe food for thought.
Good luck
IC
