Dr. Greene's Answer
When most people hear the term “tongue-tied”, they picture someone nervous, stammering, and at a loss for words. Tongue-tie isn’t just a cartoon caricature or picturesque description of an embarrassing moment; it is a relatively common physical condition.
During fetal development, cords of tissue called frenula form in the front-center of the mouth, beginning as early as 4 weeks of gestation. The word “frenulum” comes from the Latin word for bridle. A bridle can be used to guide a horse. In roughly the same way, the frenula guide the development of the structures of the mouth. Early in development, the frenula are important, strong cords, which then recede over time. After birth, they are still useful in guiding the positions of the baby teeth as they come in.
The tiny cord between the center of the upper lip and the center of the upper gum is called the labial frenulum (or lip frenulum). If you slip your tongue up where your upper lip meets your upper gum, you can probably still feel a remnant of your labial frenulum.
Another cord between the base of the tongue and the floor of the mouth or the lower gum is called the lingual frenulum. If you lift your tongue up and look in a mirror, you probably can see the strand of tissue connecting the bottom of your tongue to the floor of your mouth — what is left of your lingual frenulum.
In some kids, the lingual frenulum is short and taut after birth, partially restricting movement of the tongue. This condition is called ankyloglossitis (don’t doctors have great names for things?) — more commonly known as tongue-tie.
In most of these children, the frenulum continues to recede during the entire first year. Their parents get to watch a part of development that usually happens in the hidden inner sanctum of the uterus.
Although tongue-tie is common, only in rare children is medical treatment necessary. If a tight frenulum is interfering with a baby’s feeding, then early treatment is indicated. To accomplish this, the tongue is “loosened” by means of very simple and effective surgery. If a baby is feeding well, however, it is usually better to wait at least a year before revisiting the question of surgery, since tongue-tie so often resolves on its own.
Treatment is again considered if the tongue-tie is affecting speech — especially making it more difficult to pronounce the “th” sound. Tongue-tie is most likely to persist and pose a problem if the insertion points of the frenulum are on the very tip of the tongue and also on the top ridge of the bottom gum. A strong family history is also suggestive of a need for surgery at some point.
It is normal for toddlers to speak in a charming, partially understandable way. We expect kids to have mostly intelligible speech by age three (i.e. others besides their parents understand more than half of their words easily). Your 2 1/2-year-old’s speech may be normal for his age, or may be hindered by his tongue-tie. I would recommend an evaluation by an experienced speech pathologist. This will give you useful information and may help force the hands of doctors and insurance companies. If the speech therapist feels that the tongue-tie is indeed hindering his language development, then I would certainly ask a pediatric otolaryngologist (ear, nose, and throat surgeon) to consider a simple surgical release for an otherwise healthy child.
If the therapist is unconcerned about his speech development, the simple release surgery could still be performed for cosmetic reasons. Often, Christine, “cosmetic” reasons are not superficial reasons. They can affect such core issues as self-esteem, physical comfort, and development of social interactions. Rarely will you encounter an easier way to free your son from bonds that are holding him back!
