Does latex do anything special with periods? If so, is there a way to differentiate end-of-sentence periods from periods indicating abbreviation?
Typography – Is a Period After an Abbreviation the Same as an End of Sentence Period?

You insert the period as part of the equation and therefore also in math mode, as opposed to putting it outside the equation.
\documentclass{article}
\begin{document}
If \[x\rightarrow y,\] then \[y\rightarrow z.\]
\end{document}
Naturally, this may lead to a slightly off-center spacing due to the punctuation (albeit marginally visible). However, to correct for this, you can use \phantom{<punct>} on the opposite side:
\documentclass{article}
\begin{document}
If \[\phantom{,}x\rightarrow y,\] then \[\phantom{.}y\rightarrow z.\]
\end{document}

There is the issue of end of sentence space vs. space between words. By default the first one is bigger.
In the first line the space after the 2nd period is typeset like an end of sentence space. In the second line the space after the 2nd period is typeset like a normal inter-word space:
You can setup with
\frenchspacingthat the end of sentence space is not different from the normal inter-word spacing.An
\@before a period sets up end of sentence spacing. This is needed, if the sentence ends with a one-capital-letter word.
