I bit into a semi-cold grape today and felt a ZING on one of my back teeth.
This is one that got a major filling in February.
And it has never felt quite right since.
It's still buzzing.
And I'm a little bit ticked.
UPDATE: the tooth was fine on wednesday, and it's fine today (thursday). I think I'm just ultra-sensitive after the root canal trauma of 2007. Any little thing sets me off and I go into panic mode.
