Restrictive lingual frenulum, also known as ankylglossia or tongue-tie, is a condition where the tongue is tethered to the floor of the mouth and can limit the mobility of the tongue. Tongue-ties can be found in the front (anterior) or back (posterior) of the tongue.
Tongue-ties are graded based on the level of tongue restriction. It's important to note that diagnosis goes beyond a simple visual examination, as function is a key factor. Tongue-ties can have a genetic component and often go undiagnosed due to a lack of awareness among healthcare practitioners. Unfortunately, not all clinicians may not be familiar with the latest evidence-based protocols in the managemet of this condition.
