The lingual frenum connects the tongue to the floor of the mouth. Sometimes, the lingual frenum can run all the way to the tip of the tongue, causing a person to be tongue-tied. This is shown in the photo below:
A restrictive lingual frenum is a common occurrence in young children. Normally, children are able to accommodate well to a prominent lingual frenum and can surprisingly eat and speak normally. If the attachment is extends all the way to the tip of the tongue, then a frenectomy may be the only choice to give the child normal tongue function by increasing its range of motion.
A lingual frenectomy is a simple procedure and involves numbing the tongue with an anesthetic. A small releasing incision with a laser is then made that frees the tongue from the floor of the mouth.
