When we discuss dental stability as a dentist Ivanhoe, many people immediately think of brushing, flossing, and regular check-ups. However, there’s a subtle yet significant factor that often goes unnoticed: tongue thrust habits. At Ivanhoe Smiles, we’ve observed countless cases where this seemingly innocuous behaviour has led to substantial changes in dental alignment over time. Tongue thrust, also known as orofacial muscular imbalance, occurs when the tongue presses against or between the teeth during swallowing, speaking, or even at rest.
The human tongue is a remarkably powerful muscle, and when it consistently applies pressure in the wrong direction, it can gradually shift teeth out of their ideal positions. This process doesn’t happen overnight, but rather develops slowly over months and years. What makes tongue thrust particularly challenging is that many people remain completely unaware they’re doing it. The habit often begins in childhood and, if left unaddressed, can persist well into adulthood, creating ongoing challenges for dental stability.
Several factors contribute to the development of tongue thrust patterns. During infancy, all babies naturally use a forward tongue motion whilst feeding. For most children, this pattern transitions to a mature swallowing pattern by around age six. However, some individuals retain this infantile swallowing pattern, which becomes the foundation for tongue thrust habits. Extended use of dummies, prolonged bottle feeding, and thumb sucking can all reinforce this pattern beyond the typical developmental window.
Additionally, anatomical factors such as enlarged tonsils, chronic nasal congestion, or tongue-tie can contribute to improper tongue positioning. When breathing passages are restricted, the tongue naturally moves forward to help maintain an open airway. Over time, this compensatory position becomes habitual, even after the initial obstruction is resolved. As a dentist Ivanhoe residents trust, we frequently encounter patients whose tongue thrust habits have developed as a response to these underlying conditions.
Recognising tongue thrust early can prevent years of dental complications. Some telltale signs include:
The persistent pressure exerted by tongue thrust can undermine even the most successful orthodontic treatment. We’ve seen patients who’ve completed years of braces treatment, only to experience relapse because their tongue thrust habit remained unaddressed. The tongue can exert several hundred grams of force with each swallow, and considering we swallow between 1,200 and 2,000 times daily, the cumulative pressure becomes substantial. This constant force gradually pushes teeth forward, creating spacing issues and compromising the bite relationship between upper and lower teeth.
Beyond aesthetic concerns, tongue thrust can affect jaw development in growing children. The abnormal pressure patterns can influence how the upper and lower jaws grow relative to each other, potentially leading to skeletal imbalances that become increasingly difficult to correct with age. This is precisely why early intervention proves so valuable in managing these habits before they create lasting structural changes.
Addressing tongue thrust requires a multifaceted approach. Myofunctional therapy, which involves exercises to retrain the tongue and facial muscles, forms the cornerstone of treatment. These exercises help establish proper tongue posture and swallowing patterns. When we work with patients at our dentist Ivanhoe, we often collaborate with speech pathologists and myofunctional therapists to ensure comprehensive care.
For some patients, orthodontic appliances can assist in breaking the habit whilst simultaneously correcting dental misalignment. These devices create a physical barrier that reminds the tongue to maintain proper positioning. However, appliances alone rarely solve the problem permanently without accompanying behavioural modification and muscle retraining.
Understanding the relationship between tongue habits and dental stability empowers patients to take proactive steps towards maintaining their oral health. At our practice, we emphasise the importance of comprehensive assessments that look beyond surface-level concerns. By identifying and addressing tongue thrust habits early, we can help preserve dental stability for years to come, ensuring that orthodontic investments remain protected and natural tooth positions stay secure throughout life.
