Tongue Thrusting

Tongue thrusting (otherwise known as immature swallow or reverse swallowing) is an orofacial muscular imbalance that causes the tongue to protrude through the anterior incisors when a person swallows, speaks, and sometimes  even when the tongue is at rest. If left unaddressed, it can cause serious orthodontic problems.


Tongue thrusting is very common in babies until they are about 6 months old or so. By this time, most babies have grown out of it, and this fact is considered an indicator that they’re ready to start eating baby food.

If, however, the child continues to tongue thrust beyond the age of 4, it may cause serious orthodontic problems. This is one of the reasons that it's important that children are evaluated by an orthodontist at an early age.

A typical person swallows on average 1,200 - 2,000 times per day, and each swallow places about 4 pounds of pressure on the inside of the mouth. Combined with tongue thrusting, this pressure can force the teeth out of alignment.

Those who tongue thrust can develop a variety of orthodontic problems. In fact, if tongue thrusting isn't addressed, it might even cause dental and orthodontic issues to relapse after treatment.

Tongue Thrust Treatment

Fortunately, tongue thrust is a highly treatable condition. A dental appliance or night guard can be used to create a physical barrier that makes tongue thrusting more difficult or uncomfortable for the patient, thus training him out of the habit.

Alternatively the patient can undergo orofacial myofunctional therapy. This therapy is designed to re-train the muscles associated with swallowing by changing the swallowing pattern.

If you or your child are suffering from tongue thrusting, or if you have orthodontic problems as a result of it, contact our team at Langley Orthodontics today for an orthodontic evaluation.
