If your site has many 404 errors, it’s possible that it will impact in search engine ranking too. If search engine spiders are constantly presented with non-existent pages, they’ll penalize your site for having invalid links. However few error pages may not have any drawbacks.
There are number of plugins that make handling WordPress 404 errors effortlessly but that also mean you need to install the plugin and adding an additional burden on your web host.

<?php header("HTTP/1.1 301 Moved Permanently"); header("Location: ".get_bloginfo('url')); exit(); ?>
Once done every 404 page will be redirected to the homepage.
