You can wrap each sentence in <span class="sentence"> ... </span>, then use CSS to apply a style to the sentence class. This may seem complex for such an issue, but it does obey the rule of separating content and style. Another advantage of this approach is that you can have a JS checkbox on the page so people who feel strongly about this can choose which style they prefer. :) Creating a sentence class as above does for sentences what <p> ... </p> does for paragraphs.
