Navigation cuts off words

Hello,

I have a Problem with the Navigation of my Homepage when displayed in Tablet or Mobile Format. Like you can see in the picture it cuts of the "N" of Schulkooperationen. Of course it would be an easy fix to simply make the words smaller. However I'm hoping there is another possibility by using costum CSS to remain the readability.

Thanks a lot!
