How much time was there between first and second tooth cutting?

F

Hi ladies, my nine month old cut her first bottom tooth just over two weeks ago and everybody has told me that these teeth always come out in pairs and the second tooth should cut within a day or two of the first. Well... like I said, it’s been over two weeks and this second tooth isn’t showing even the slightest sign of cutting. My baby also isn’t showing any teething symptoms anymore :/
