Metlic feel to inside of one tooth.

[everway9]

Hi everyone.

Sometimes when I place my tongue on one of my teeth I get a metalic sensation. Exactly the same as if I put a coin in my mouth. It's a rare occurrence, maybe once a week or so.

It's happened throughout my life randomly on different teeth and I've always wondered what causes this sensation. I don't have a metalic taste in my mouth just the sensation of metal when my tongue comes into contact with a tooth.

Can anyone explain why this happens?

Many thanks in advance.

Other than tooth sensitivity, galvanism can cause a metallic or salty taste in the mouth, increase salivary secretion, and burning or tingling sensation of the tongue.
