Tongue-ties refer to cases where the frenulum connecting the tongue to the base of the mouth is too short or tight, causing interference with speech or feeding. Synonyms for tongue-ties include ankyloglossia, tongue-tether, and short frenulum. Other terms that are often used to refer to this condition include tongue restriction, tongue restriction syndrome, and tongue-tie disorder. While these terms may be used interchangeably, they all describe the same underlying issue: a restricted range of motion in the tongue due to the abnormal positioning or structure of its connecting tissues. Tongue-ties can cause significant challenges for individuals, but early intervention can often help address the problem.
