The space between the numbering of the subsections and their titles in TOC

Question

I wonder why the space between the numbering and the titles for those sections starting from 10 is less than the space for those sections between 1 and 9. I want it to increase since the numbering seems too close to the titles. How should I achieve it ?. I searched and asked many times about this problem but I got no a useful solution. I just use the command \tableofcontents in my article documentclass. Here is a screenshot of what I meant.

I appreciate any help, and I hope my question not to be marked as duplicate because I did not get any benefit from any other like questions.

This is what I use:

\documentclass[12pt,a4paper]{article}
\usepackage[utf8]{inputenc}
\usepackage{geometry}
\geometry{footskip=15pt}
\usepackage{amsmath}

\usepackage{tocloft}

\begin{document}
\tableofcontents
\end{document}

It is not recommended to change only the space of the 10.x etc. numbers, because in this case the alignment of the text in the ToC would be broken. But you can change the reserved width for the number of all ToC entries of the sub-section level and other levels without any problem. — Schweinebacke, May 29 '17 at 05:56

Please describe what change you have made to get the effect. — Andrew Swann, May 29 '17 at 06:14
We need to allign right for section numbers then the problem can be solved, originally it is center allign, this question can be mark as duplicate and already solved here by Heiko Oberdiek https://tex.stackexchange.com/questions/67523/right-align-numbers-in-toc @AndrewSwann — Biki Teron, May 29 '17 at 06:19
The aspect "I want it [the space between the number and the title] to increase since the numbering seems too close to the titles." of the question is missing in this answer, isn't it? — Schweinebacke, May 29 '17 at 06:25
Spacing can be made by using ~~ in \subsection{~~The Cotangent Bundle} but if we don't do allignment then it will not looks good, so before doing we need to allign first then spacing can be made as mentioned. @Schweinebacke — Biki Teron, May 29 '17 at 06:33
I was really asking you to update your answer so that a reader can get an explanation of what you have changed and why it works. Now I am inclined to think you should just have provided a link to Heiko's answer in a comment. — Andrew Swann, May 29 '17 at 06:49
You should not add ~~ in the \subsection argument, because it will be placed also in the heading and (if used) in the running head. — Schweinebacke, May 29 '17 at 07:57
