Should I be concerned DS hasn’t lost any teeth yet?

[OhOk]

This seems like such a stupid problem to be worried about but DS will be 7 in April and hasn’t had so much as a wobbly tooth. Kids as young as reception seem to be losing theirs but he is year 2 and... nothing?!

Is this normal? Thanks for any replies

My ds was 7 in February and only started losing teeth from around May or June he has lost 4 so far.
DD was nearly 8 before she lost any and at 12 still has 2 or 3 to lose.
Our dentist wasn’t concerned, said it was a good thing, as the the older they get the adult teeth the better and they are better able to brush them correctly.
