Well my boyfriend has this white spot on one of his front teeth. I'm not sure how to explain it. All of his teeth are the same color, but there is one spot that is whiter than the rest. He thinks it is getting worse....what could be causing this?
This can be caused by very mild dental flourosis (I think) where the body has too much flouride. If he's not sure, get him to check it out with his dentist but white spots on the teeth is pretty common. I'm by no means a dentist, just knowledgable in the area :-)
