Accessing a model in a much used helper

Hi all,
I have this helper function which gets texts from a database to show on the website.
But I wonder if this can be optimized in terms of efficiency.
The getSiteText() function can be called many times on a single page.
Do I really need to call the TextModel every single time, or are there better ways?

PHP Code:

function getSiteText(string $textName): string
{
    $textModel = new TextModel();

    return $textModel->getText($textName);
}
