Table of contents not showing correctly

Question

Anyone knows how to solve this? The problem is that the number is very close to the title when the number reaches 10. I will add an image to reference this. Thanks in advance!

These are all the packages (and the type of document) I used:

\documentclass[12pt]{article}
\usepackage{amsmath} 
\usepackage{graphicx} 
\usepackage[margin=1in]{geometry} 
\usepackage{cite} 
\usepackage{float}
\usepackage[final]{hyperref}
\usepackage{amsmath}
\usepackage{xcolor}
\usepackage[spanish]{babel}
\usepackage[bottom]{footmisc}
\usepackage{titlesec}
\usepackage{hyperref}
\usepackage{soul}
\usepackage{comment}
\usepackage{subfiles}

NOTE: This question is related but that solution doesn't work perfectly because it changes the spacing and removes the period after the number. I only want to change that space between number and title. Thanks!

EDIT: Added MWE:

\documentclass[12pt]{article}
\usepackage{amsmath} 
\usepackage{graphicx}
\usepackage[margin=1in]{geometry}
\usepackage{cite} 
\usepackage{float}
\usepackage[final]{hyperref}
\usepackage{lipsum}
\usepackage{amsmath}
\usepackage{xcolor}
\usepackage[spanish]{babel}
\setlength{\parindent}{0em}
\setlength{\parskip}{.5em}
\renewcommand{\baselinestretch}{1.35}
\usepackage[bottom]{footmisc}
\usepackage{titlesec}
\usepackage{hyperref}
\setcounter{secnumdepth}{4}
\setcounter{tocdepth}{4}

\begin{document}

\thispagestyle{empty}
\setlength\headheight{0pt} 
\begin{center}
        {\Large\bfseries Resume\par}
        \vspace{0.5cm}
\end{center}

\tableofcontents
\pagebreak

\section{A}
\section{B}
\section{C}
\section{D}
\section{E}
\section{F}
\section{G}
\section{H}
\section{I}
\section{J}
\section{K}
\section{L}
\section{M}

\end{document}

This will display:

Answer 1

The solution remains the same as in Roman numerals become “too wide” in table of contents, except for some shuffling of the package loading:

\documentclass{article}

\usepackage{tocloft}
\usepackage[spanish]{babel}
\usepackage{hyperref}

\setcounter{secnumdepth}{4}
\setcounter{tocdepth}{4}
\setlength{\cftsecnumwidth}{3em}

\begin{document}

\tableofcontents

\clearpage

\section{A}
\subsection{AA}
\section{B}
\section{C}
\section{D}
\section{E}
\section{F}
\section{G}
\section{H}
\section{I}
\section{J}
\section{K}
\section{L}
\section{M}

\end{document}

You can also adjust the spacing manually by patching \l@section:

\usepackage{etoolbox}
\makeatletter
\patchcmd{\l@section}% <cmd>
  {1.5em}% <search>
  {2em}% <replace>
  {}{}% <success><failure>
\makeatother

Answer 2

Use the tocloft package and \cftsecnumwidth to change the space for section numbers in the ToC.

EDIT

Changed the answer to meet the OP's desire (in a comment) to have extra space between the ToC entries.

\documentclass{article}
\usepackage{comment}

\begin{comment}
\usepackage[explicit]{titlesec}

\titleformat{name=\section}[block]
{\normalfont\normalsize\bfseries}{\thesection~~#1}{1em}{}[
\addcontentsline{toc}{section}{\thesection~#1}]
\end{comment}

\usepackage{tocloft}
%\setlength{\cftsecnumwidth}{3.5em}  % change this to suit more space for section numbers
\makeatletter
\renewcommand{\numberline}[1]{%    % don't put section numbers in a box
  {\@cftbsnum #1\@cftasnum\hfil}\@cftasnumb}
\makeatother
\renewcommand{\cftsecaftersnum}{\hspace{1em}} % change this to suit space after section number

\setlength{\cftparskip}{\baselineskip} % put more space between entries
