Adjusting to new dentures—whether full or partial—can sometimes affect your speech temporarily. This adjustment period typically lasts a few days but may extend to a few weeks in some cases. The tongue, like other muscles in the body, has “memory” and may need time to adapt to its new environment. As you speak or read aloud, your tongue will gradually become accustomed to the changes in thickness, the acrylic material, the frame (in the case of partial dentures), and the placement and size of the teeth. With practice, your speech should return to normal. If speech difficulties persist beyond a few weeks, be sure to contact your denturist for assistance.
