Bitter taste from top of crown

[Dion Furguson]

Crown broke.
Bitter taste began from inside top of crown.
Sweet bitter taste.
Went to 2 dentists.
They have no clue what it is.
Got new crown.
Still have bitter taste.
Dentist doesn't know why.
No pain.
Can't stop licking the area.
Driving me CRAZY!!!

Are you sure you don't have gastric reflux? Acid can travel all the way to your teeth and it has a strange metallic bitter taste.
