Hi M.~
I wouldn't worry too much. My son was textbook. All the right teeth at all the right times.
Now my daughter? Completely a different story ... got her bottom tooth and then the 2 canines and that was it for the longest time. We called her the littlest vampire. I did call my dentist cause like you I was worried that there were no other teeth coming and he said that those eruption schedules that moms see are just schedules and not a "definite". I am happy to report that she has front teeth now and more bottom as well.
Good luck!
