worried about teeth

[DoubleK]

My DD slipped over on the tiles the other day, she went face first, and ended up chipping a tiny piece off her front tooth its noticeable, but only very small.

i noticed yesterday that her other front tooth looks darker than the rest... she wont let me have a good look, i can only notice it from about a metre and a half away.. if i go any closer, i cant really notice it.

could dd have damaged her tooth by knocking it against the tiles? its not out of place or anything, but im worried about it.

i doubt she would let a dentist have a look.. what should i do??
