DS is 9mo and doesn't have any teeth. At what point should I be concerned?

He will be 9mo this week. He seems 'normal' otherwise, just hasn't got any teeth yet, didn't know at what stage I should be concerned about this...?

my ds is just getting all four of his canines at once, he is 2 and 3 months...even then he wont have a full set yet, his first teeth were his two front ones that he got when he was 13 months. They can be 3 before they get a full set and the later they get them the better (my dentist said) Dont worry at all!
