Google automatically does a re-crawl of the website. In order to speed up the process of re-crawling your website, you can take the following steps:
1. Clear all website and server-level cache -> Here is a guide on how to clear WordPress cache: https://blogvault.net/how-to-clear-wordpress-cache/
2. Submit a crawl request to Google -> Follow this guide to request a recrawl. We recommend using the Sitemap method to re-crawl the entire website & not just one page -> https://support.google.com/webmasters/answer/6065812?hl=en
Once Google's bots have completed the recrawl, the search results will be updated to reflect the latest version of your website.
