Underline overfull \hbox

I am getting the following Overfull \hbox (0.10945pt too wide) in paragraph at lines 12--13. How could I prevent this?

I am using \, inside \dotuline because I want to use a little bit longer dotted underline.

\documentclass[12pt]{report}\usepackage[english]{babel}\usepackage[utf8]{inputenc}\usepackage[T1]{fontenc}\usepackage[left=2.5cm, right=2.5cm, top=2.5cm, bottom=2.5cm, noheadfoot]{geometry}\usepackage[dot]{dashundergaps}\setlength\parindent{0pt}\begin{document}Lorem \dotuline{\,\,LoremLoremLoremLoremLoremLoremLoremLorem LoremLoremLoremLoremLorem\,\,} Lorem Lorem Lorem Lorem Lorem Lorem Lorem Lorem Lorem Lorem Lorem Lorem Lorem Lorem Lorem Lorem\end{document}

UPDATE

\documentclass[12pt]{report}\usepackage[english]{babel}\usepackage[utf8]{inputenc}\usepackage[T1]{fontenc}\usepackage[left=2.5cm, right=2.5cm, top=2.5cm, bottom=2.5cm, noheadfoot]{geometry}\hyphenation{Lor-em}\usepackage[dot]{dashundergaps}\setlength\parindent{0pt}\begin{document}Lorem \dotuline{\,\,Lor\-emLor\-emLor\-emLor\-emLor\-emLor\-emLor\-em} Lor\-em Lor\-emLor\-emLor\-emLor\-emLor\-emLor\-em Lor\-em Lor\-em Lor\-em Lor\-em Lor\-em Lor\-em Lor\-em Lor\-em Lor\-em Lor\-em Lor\-em Lor\-em\end{document}

In this case I am getting the following Overfull \hbox (20.50162pt too wide) in paragraph at lines 13--14
