Why does my 2 yo have silver lines on her tooth?

Question

My toddler has these silvery metallic lines on the top half of one of her front lower teeth. They will not brush off. She does not drink any juice, her teeth are brushed at least twice a day, eats no sweets beyond fruit and does not go to bed with bottle/sippy cup etc. The lines are thin, silver and kind of shiny though not noticeable from a distance. Any ideas?

Answer 1

did you figure out what the lines were...my son has some on his teeth

 

Answer 2

 I know this is an old post... But, what if these lines were on a healthy adult on the lower teeth. sorry , in the lower teeth, couldn't be scratched off. If it lasted two weeks... And a Month later spontaneous vertigo persisted for a week that couldn't be explained by neurologists... 

 Just would love a starting point to try to figure out if it'll have any lasting effects.

 Thank You
