Initially, some patients may notice a slight alteration in their speech, such as a lisp, as they adjust to the new thickness and shape of their teeth. This adjustment period is typically short-lived, lasting only a few days to a week. As you become accustomed to the feel of your veneers, any speech impediments caused by the veneers should disappear. If speech issues persist, consult your dentist as the veneers might require slight adjustments.
